Product details
Overview
P4KE7.5HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for primary overvoltage protection of sensitive electronics. It features a 7.13 V minimum and 7.88 V maximum breakdown voltage at 10 mA test current, 6.40 V stand-off voltage, 11.3 V maximum clamping voltage at 35.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE7.5HE3/54 datasheet, P4KE7.5HE3/54 pinout, P4KE7.5HE3/54 application, or P4KE7.5HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, clamping performance under surge conditions, and direct alternatives for circuit protection redesign or BOM optimization.
Technical Context
The P4KE7.5HE3/54 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its specified breakdown range (7.13–7.88 V). Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching transients before downstream IC damage occurs.
Rated for 400 W peak pulse power (10/1000 μs), it sustains 35.4 A peak pulse current while clamping to ≤11.3 V - ensuring protected circuits remain below safe operating thresholds. Thermal resistance is 66 °C/W (junction-to-lead), supporting reliable operation up to 175 °C junction temperature with appropriate PCB copper area.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V microcontroller power inputs in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VCC and GND to clamp positive transients above 6.4 V. Use Value: Limits voltage excursion to ≤11.3 V during 35.4 A surge, preventing MCU latch-up or permanent damage per ISO 7637-2 compliance. |
Use Scenario: Safeguarding analog output lines (e.g., 4–20 mA transmitter) from field-induced surges in factory automation systems. IC Role / Device Role / Timing Role: TVS connected across signal and return path to absorb common-mode transients before reaching ADC input. Use Value: Clamps induced spikes within nanoseconds, preserving signal fidelity and avoiding ADC saturation or op-amp damage. |
| Consumer Device USB Port Protection | Telecom Line Card Surge Suppression |
Use Scenario: Adding secondary overvoltage defense on VBUS line of USB 2.0 ports in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Standoff-rated TVS placed upstream of USB switch IC to block >6.4 V faults before they propagate. Use Value: Withstands 400 W surges while maintaining <500 μA leakage at 5 V, ensuring no impact on USB enumeration or power budget. |
Use Scenario: Front-end protection of Ethernet PHY interface on telecom base station line cards subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS used in conjunction with gas discharge tube (GDT) for staged protection of RJ45 magnetics. Use Value: Fast clamping (≤1 ns) complements slower GDT, limiting let-through voltage to PHY ICs during combined threat scenarios. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V nominal VBR; 600 W PPPM; higher thermal mass but larger footprint | Better suited for higher-energy surges where PCB space allows SMB footprint | Select SMBJ7.0A when board layout permits larger package and system requires >400 W surge margin |
| 1.5KE7.5A | Same DO-41 package; identical VBR range; 1500 W PPPM; higher clamping voltage (12.0 V) | Used where higher surge energy must be absorbed, accepting elevated clamping level | Choose 1.5KE7.5A only if system design tolerates ≥12.0 V clamping and requires 1500 W rating |
Compared with SMBJ7.0A and 1.5KE7.5A, the P4KE7.5HE3/54 offers optimal balance of compact DO-41 size, AEC-Q101 qualification, and 400 W capability - making it preferred for space-constrained automotive and industrial PCBs where 11.3 V clamping is acceptable.

FAQ
What is the breakdown voltage tolerance of the P4KE7.5HE3/54?
The P4KE7.5HE3/54 has a guaranteed breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, representing ±5% tolerance around the nominal 7.5 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable circuit protection design without derating overhead.
Is the P4KE7.5HE3/54 suitable for bidirectional transient suppression?
No, the P4KE7.5HE3/54 is a unidirectional TVS diode, identified by its cathode band marking and specified VBR only in reverse bias. For bidirectional protection, Vishay offers the P4KE7.5CA variant; using P4KE7.5HE3/54 in AC-coupled or symmetrical surge paths would result in forward conduction and failure.
Does the HE3 suffix on P4KE7.5HE3/54 indicate AEC-Q101 qualification?
Yes, the HE3 suffix explicitly denotes RoHS-compliant construction with AEC-Q101 qualification per Vishay's ordering nomenclature. This certification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge - confirming suitability for automotive under-hood and chassis applications.
What is the maximum clamping voltage of the P4KE7.5HE3/54 under surge conditions?
The P4KE7.5HE3/54 clamps to a maximum of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 μs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can the P4KE7.5HE3/54 replace the P4KE7.5A-E3/54 in existing designs?
Yes, the P4KE7.5HE3/54 is a direct replacement for P4KE7.5A-E3/54 in terms of electrical specs and DO-41 package, with the added benefit of AEC-Q101 qualification. Both share identical VBR, VWM, and VC values; the HE3 version simply extends reliability validation for automotive use without layout or schematic changes.
