Product details
Overview
P6KE75HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 71.3 V minimum breakdown voltage (VBR), 64.1 V maximum stand-off voltage (VWM), 103 V clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE75HE3/54 datasheet, P6KE75HE3/54 pinout, P6KE75HE3/54 application, or P6KE75HE3/54 equivalent, this AEC-Q101-qualified DO-15 device delivers verified surge immunity for 12 V and 24 V systems, with validated thermal resistance (RθJL = 20 °C/W), low leakage (<1 µA at VWM), and RoHS-compliant matte tin-plated leads per J-STD-002.
Technical Context
The P6KE75HE3/54 operates as a unidirectional avalanche diode, clamping transient overvoltages above its breakdown threshold while maintaining low leakage below 64.1 V. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Thermally, it supports continuous operation from –55 °C to +175 °C junction temperature, with derated power dissipation above 25 °C ambient and defined surge capability up to 100 A (8.3 ms half-sine). The device is rated for repetitive 0.01% duty cycle pulses and complies with UL 497B recognition (QVGQ2) for telecom and automotive protectors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 64.1 V maximum - ensures no conduction during normal 12 V/24 V rail operation with margin |
| VBR (min/max) | 71.3 V / 78.8 V at 1 mA - defines precise avalanche onset for predictable clamping behavior |
| VC @ IPPM | 103 V at 5.8 A - limits downstream voltage stress during 600 W transient events |
| IPPM | 5.8 A peak pulse current (10/1000 µs) - quantifies maximum surge energy absorption capacity |
| PPPM | 600 W - enables robust protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |
| TJ max | +175 °C - supports under-hood automotive placement without thermal derating penalties |
| RθJL | 20 °C/W - allows direct PCB copper pour heatsinking for sustained surge handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | DO-214AA package; lower RθJA (50 °C/W vs. 75 °C/W); same VWM/VC specs | Better suited for surface-mount layouts with limited board space; requires rework of footprint | Select SMBJ75A when automated SMT assembly and thermal performance outweigh axial lead compatibility needs. |
| 1.5KE75A | Same DO-15 package; higher PPPM (1500 W); larger VC (121 V); non-AEC-Q101 | Acceptable for non-automotive industrial use where higher surge margin is prioritized over clamping tightness | Choose 1.5KE75A only for cost-sensitive non-automotive designs requiring >1 kW surge headroom. |
Compared with SMBJ75A and 1.5KE75A, the P6KE75HE3/54 uniquely balances AEC-Q101 compliance, DO-15 axial form factor, and optimized 103 V clamping - making it the preferred choice for legacy automotive harness interfaces and through-hole production lines requiring zero layout change.

FAQ
What is the clamping voltage of the P6KE75HE3/54 under standard test conditions?
The P6KE75HE3/54 has a maximum clamping voltage (VC) of 103 V when subjected to a 10/1000 µs waveform at 5.8 A peak pulse current. This value is measured per JEDEC standards and reflects worst-case voltage seen by downstream components during surge events - critical for validating MOSFET and IC voltage ratings in 24 V automotive designs where the P6KE75HE3/54 is commonly deployed.
Is the P6KE75HE3/54 suitable for automotive applications?
Yes, the P6KE75HE3/54 is AEC-Q101 qualified and carries the HE3 suffix indicating compliance with JESD 201 Class 2 whisker resistance testing. Its operating junction temperature range (–55 °C to +175 °C), UL 497B recognition, and validated surge performance per ISO 7637-2 make it approved for under-hood and body electronics - including power supply inputs in ECUs where the P6KE75HE3/54 serves as first-line transient defense.
How does the P6KE75HE3/54 differ from the commercial-grade P6KE75A-E3/54?
The P6KE75HE3/54 differs from P6KE75A-E3/54 solely in qualification level: HE3 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, while E3 indicates commercial grade with Class 1A whisker testing. Both share identical electrical specs (VWM, VBR, VC, PPPM) and DO-15 packaging - meaning the P6KE75HE3/54 is a drop-in replacement for automotive use without changing circuit design or layout.
What is the maximum reverse leakage current for the P6KE75HE3/54 at rated stand-off voltage?
The P6KE75HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM = 64.1 V) and 25 °C ambient. This ultra-low leakage ensures negligible power loss in always-on automotive modules and preserves battery life in telematics units - a key specification confirmed in the Vishay datasheet Table "ELECTRICAL CHARACTERISTICS" for the P6KE75A variant, which applies identically to P6KE75HE3/54.
Can the P6KE75HE3/54 be used in bi-directional configurations?
No, the P6KE75HE3/54 is a unidirectional TVS diode - identified by the "A" suffix and cathode band marking. Bi-directional variants require the "CA" suffix (e.g., P6KE75CA). Using the P6KE75HE3/54 in bi-directional applications would result in forward conduction during negative transients, causing failure. For symmetric surge protection, select P6KE75CAHE3/54 or equivalent, not the P6KE75HE3/54.
