Coverage
Coverage is stated one domain at a time and is never rolled up. A domain marked open is a question that has not been answered; it is not a finding that the part is unsuitable. A record with no open domains has not thereby been declared safe.
electrical-limits
Coverage ID: cov-pesd24vs1ub-electrical-limits · Status: COVERED
Reason: Standoff (24 V), breakdown (26.5-27.5 V at 5 mA), clamp (36 V at 1 A; 70 V at 3 A, 8/20 us), peak pulse power (160 W), ESD withstand (23 kV IEC contact), leakage (50 nA max), and capacitance (50 pF max) are primary-source confirmed from the 2026-08-06 Nexperia product data sheet.
Facts in this domain:
distributor-identity
Coverage ID: cov-pesd24vs1ub-distributor-identity · Status: COVERED
Reason: Exact orderable C85382 is bound to Nexperia PESD24VS1UB,115 by the dated LCSC product page identity extract.
Facts in this domain:
cc-line-fitting-decision
Coverage ID: cov-pesd24vs1ub-cc-line-fitting-decision · Status: OPEN
Reason: D6/D7 are DNP layout-phase provisions; whether to fit CC-line ESD protection (and whether the 24 V standoff / 36 V at 1 A clamp profile is the right choice against the CC pins it would protect) is deferred to the decision and bench waves; fact-pesd24vs1ub-dnp-provision records the open state.
Facts in this domain:
Blocked by: these facts must be resolved before the domain can close. Each is listed in full under Facts.
Facts
Each fact keeps its value, its unit, the conditions it holds under, where it came from and how far it has been confirmed as separate fields, because they are separate claims. A value without its conditions is not the same fact, and a verdict is about the evidence for the value, not about the part.
GUARANTEED_ELECTRICAL
A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.
Fact: fact-pesd24vs1ub-leakage
Value: 50 · Unit: nA
Conditions: maximum reverse leakage IRM at VRWM 24 V, Tamb=25 C (1 nA typical)
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 6 Characteristics, IRM row (printed page 4)
Fact: fact-pesd24vs1ub-capacitance
Value: 50 · Unit: pF
Conditions: maximum diode capacitance Cd at f=1 MHz, VR=0 V, Tamb=25 C (23 pF typical); low enough for the CC-line signaling application
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
TRANSIENT
Behaviour during a short event — startup, a switching edge, a fault or a surge.
Fact: fact-pesd24vs1ub-pppm
Value: 160 · Unit: W
Conditions: rated peak pulse power at tp=8/20 us, non-repetitive
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 5 Limiting values, PPPM row (printed page 3)
Fact: fact-pesd24vs1ub-esd
Value: 23 · Unit: kV
Conditions: maximum ESD withstand per IEC 61000-4-2 contact discharge (ten non-repetitive pulses); HBM MIL-STD-883 rating is 10 kV
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 5 Limiting values, ESD maximum ratings rows (printed page 3)
PROTECTION_STANDOFF
The voltage a protection device is expected to sit at without conducting.
Fact: fact-pesd24vs1ub-standoff
Value: 24 · Unit: V
Conditions: maximum reverse standoff voltage VRWM at Tamb=25 C
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
PROTECTION_BREAKDOWN
The voltage at which a protection device begins to conduct.
Fact: fact-pesd24vs1ub-breakdown
Value: 26.5 to 27.5 · Unit: V
Conditions: breakdown voltage VBR minimum/maximum (typical 27 V) at IR 5 mA, Tamb=25 C
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 6 Characteristics, VBR row (printed page 4)
PROTECTION_CLAMP
The voltage a protection device clamps to while conducting its rated surge current.
Fact: fact-pesd24vs1ub-clamp-1a
Value: 36 · Unit: V
Conditions: maximum clamping voltage VCL at IPPM 1 A, non-repetitive 8/20 us pulse, Tamb=25 C
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 6 Characteristics, VCL row at IPPM = 1 A (printed page 4)
Fact: fact-pesd24vs1ub-clamp-3a
Value: 70 · Unit: V
Conditions: maximum clamping voltage VCL at IPPM 3 A, non-repetitive 8/20 us pulse, Tamb=25 C
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-pesd24vs1ub-nexperia-primary: Table 6 Characteristics, VCL row at IPPM = 3 A (printed page 4)
PROJECT_STATE
A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.
Fact: fact-pesd24vs1ub-manufacturer
Value: Nexperia · Unit: NONE
Conditions: exact orderable identity; official product data sheet authored and served by Nexperia
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Fact: fact-pesd24vs1ub-identity
Value: lcsc=C85382; manufacturer=Nexperia; mpn=PESD24VS1UB; variant=ordering code PESD24VS1UB,115 (tape/reel), SOD-523; LCSC listing stock 100540 units at 2026-08-14 retrieval · Unit: NONE
Conditions: stable distributor identity binding of the exact orderable; same-name cross-vendor substitution prohibited; supplies no electrical or thermal authority. LCSC lists the orderable with the ,115 tape/reel packing suffix; the inventory MPN follows the datasheet part name PESD24VS1UB.
Verdict: CONFIRMED - distributor identity only · Provenance: DISTRIBUTOR-IDENTITY
Evidence: src-pesd24vs1ub-lcsc-identity: product page title row and stock row, retrieved 2026-08-14
Fact: fact-pesd24vs1ub-dnp-provision
Value: board-a D6/D7 are DNP layout-phase provisions on the CC1/CC2 lines; both placements carry dnp=true in the reviewed central inventory and no fitting decision has been made · Unit: NONE
Conditions: current project state per the reviewed central inventory (line-c85382, placements board-a D6/D7, dnp true); whether to fit CC-line ESD protection is a layout/bring-up decision deferred to the decision and bench waves; the datasheet is cited for part identity and ratings only
Verdict: NEEDS BENCH · Provenance: PROJECT-CHOICE
Evidence: src-pesd24vs1ub-nexperia-primary — Calculated project state: reviewed central inventory line-c85382 placement rows versus the Nexperia Table 2 pinning/Table 6 ratings
Pin maps

Interactions
Behaviour that is not a property of this part alone. Each interaction names the records it spans, the conditions it holds under, and how far it has been confirmed. An interaction that spans several parts appears on every one of their pages, under the same identifier, because it is equally a fact about each.
int-pesd24vs1ub-cc-provision
Records involved:
rec-pesd24vs1ub-c85382(this record)Conditions: board-a D6/D7 CC-line ESD provision: the parts are registered and footprint-provisioned but DNP; the fitting decision, and the protection-effectiveness judgment of the 24 V standoff / 36 V at 1 A clamp against the CC pins, belong to the decision and bench waves
Verdict: NEEDS BENCH
Facts this rests on:
Cross-component rules
Rules that span several parts at once and are published in full on the integration page. Each rule's verdict below is that rule's own — it is a statement about the cross-component question, not about this part — and the exact wording of what the rule refuses to conclude is published with the rule itself.
No cross-component rule names this record.
