Part Datasheet Review and Verification

flux

Reviewed the PESD5V0L4UG,115 part against the official Nexperia datasheet. The Datasheet URL was already set, so I did not change it.
Key specs
  • MPN: PESD5V0L4UG,115
  • Manufacturer: Nexperia
  • Function: low-capacitance unidirectional quadruple ESD protection diode array
  • Package: SOT353 / SC-88A, 5 leads
  • Lines protected: 4
  • VRWM: 5.0 V max
  • Capacitance: 16 pF typ, 19 pF max per diode
  • Leakage: 5 nA typ, 25 nA max at 5 V
  • Breakdown: 6.46–7.14 V
  • ESD rating: IEC 61000-4-2 level 4, up to 20 kV
  • Peak pulse power: 30 W
  • Marking: L2*
Symbol / pinout check
  • Pin 1: cathode diode 1 — matches
  • Pin 2: common anode — matches
  • Pin 3: cathode diode 2 — matches
  • Pin 4: cathode diode 3 — matches
  • Pin 5: cathode diode 4 — matches
Footprint check
  • Footprint has 5 pads, matching the SOT353/SC-88A package.
  • I could confirm pad count and pad naming, but the available layout inspection did not expose enough pad geometry to fully verify land pattern dimensions against the datasheet’s recommended SOT353 reflow footprint.
Mismatches / cleanup items
  • The part-level Package property is not set; it should be SOT353 / SC-88A.
  • Terminal Pin Type values are all Unspecified; these should ideally be set to passive/ESD diode terminal-style pins.
  • Pin descriptions are represented in designator names, but not as explicit Pin Description properties. This is not electrically wrong, but weaker metadata than the datasheet supports.

Set the terminal pin types appropriately for this ESD diode array.

flux

I’ll update the five terminal pin types to passive-style pins appropriate for an ESD diode array, then verify the schematic metadata.

flux

Updated all five terminals to Pin Type = Passive and verified the schematic metadata.
No open issues from this change. Suggested next step: add explicit Pin Description properties for each terminal so the metadata mirrors the datasheet pin table.

13V Clamp 2.5A (8/20µs) Ipp Tvs Diode Surface Mount 5-TSSOP
The PESD5V0L4UG,115 is a low-capacitance, unidirectional quad-channel Electrostatic Discharge (ESD) protection diode array from Nexperia. It is designed to protect up to four high-speed signal or data lines from ESD events and other transient voltage spikes while maintaining excellent signal integrity due to its low junction capacitance. Packaged in a compact SOT-353 (SC-88A/5-TSSOP) surface-mount package, it is well suited for space-constrained electronic designs, including communication equipment, portable devices, computers, and consumer electronics.
Key Features Quad-channel unidirectional ESD protection for up to 4 signal lines 5 V reverse standoff voltage (VRWM) suitable for 5 V interfaces Low junction capacitance (~16 pF typ.) to minimize signal distortion Low clamping voltage (13 V max.) for effective transient suppression Peak pulse power of 30 W IEC 61000-4-2 Level 4 ESD protection (up to ±20 kV) Ultra-low leakage current (typically 5 nA) Compact SOT-353 (SC-88A) surface-mount package Qualified to AEC-Q100 for automotive applications Ideal for protecting USB, communication interfaces, SIM card lines, audio/video ports, and other sensitive I/O circuits.
