Product details
Overview
P4KE75HE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor (TVS) diode in DO-41 package, designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features 71.3 V minimum breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 103 V maximum clamping voltage (VC) at 3.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the P4KE75HE3/54 datasheet, P4KE75HE3/54 pinout, P4KE75HE3/54 application, or P4KE75HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical dimensions, thermal resistance data, and direct alternative part comparisons for ESD/surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device across DC power inputs or low-speed signal paths, triggering when reverse voltage exceeds its 71.3–78.8 V breakdown range. Its glass-passivated junction ensures stable leakage (<1.0 μA at 64.1 V) and fast response (<1 ns), while the 66 °C/W junction-to-lead thermal resistance supports reliable surge dissipation without heatsinking under intermittent duty cycles.
Rated for 400 W peak pulse power (10/1000 μs), it handles up to 3.9 A IPPM and maintains clamping below 103 V - critical for protecting 75 V-rated MOSFETs and automotive ECUs against ISO 7637-2 Pulse 1/2a transients. The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | DO-214AA package; 75 V VWM; 400 W PPPM; 100 V VC @ 4.0 A | Surface-mount footprint; higher thermal resistance (RθJA = 35 °C/W vs. 100 °C/W for DO-41) | Preferred for space-constrained PCBs where reflow compatibility is required |
| 1.5KE75A | DO-201AD package; same VBR/VWM/VC; 1500 W PPPM; 100 V VC @ 15 A | Higher surge capacity but larger body; not AEC-Q101 qualified | Used where single-event 1500 W surges dominate over automotive reliability requirements |
Compared with SMBJ75A and 1.5KE75A, the P4KE75HE3/54 offers AEC-Q101 qualification and axial-lead DO-41 mounting ideal for through-hole prototyping and high-vibration automotive harness interfaces, while delivering identical 75 V-class clamping performance in a cost-optimized legacy package.

FAQ
What is the breakdown voltage range for P4KE75HE3/54?
The P4KE75HE3/54 has a guaranteed breakdown voltage (VBR) range of 71.3 V to 78.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent clamping behavior across production lots and supports design margining for 64.1 V standoff operation. The P4KE75HE3/54 maintains this specification under AEC-Q101 stress conditions.
Is P4KE75HE3/54 suitable for automotive applications?
Yes, the P4KE75HE3/54 carries the HE3 suffix, confirming full AEC-Q101 qualification - including temperature cycling, humidity bias, and mechanical shock testing. It is approved for use in engine control units, body electronics, and ADAS power supplies where 175 °C junction temperature and long-term reliability are required. The P4KE75HE3/54 meets these criteria without derating.
What is the maximum clamping voltage of P4KE75HE3/54 during a surge event?
The P4KE75HE3/54 clamps to a maximum of 103 V when subjected to its rated 3.9 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured per JEDEC JESD22-A114 and guarantees protection for downstream components rated up to 80 V, such as certain automotive PMICs and gate drivers. The P4KE75HE3/54 achieves this with a clamping ratio of ~1.37.
Does P4KE75HE3/54 have a bidirectional variant?
No, P4KE75HE3/54 is strictly unidirectional. Bidirectional variants in the same family use the "CA" suffix (e.g., P4KE75CA). The P4KE75HE3/54 features a cathode band marking and is intended for DC rail protection where polarity is fixed. Its electrical characteristics - including VBR, VWM, and VC - apply only in reverse-bias mode.
What packaging format is supplied for P4KE75HE3/54?
The P4KE75HE3/54 is supplied in 13-inch paper tape and reel packaging with a base quantity of 5500 units per reel (package code 54). Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. The P4KE75HE3/54's DO-41 body conforms to JEDEC DO-204AL outline dimensions and UL 94 V-0 flammability rating.
