Product details
Overview
P6KE56HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of DC power rails and signal lines. It features a 56 V breakdown voltage (VBR min/max: 53.2–58.8 V), 47.8 V stand-off voltage (VWM), 77.0 V maximum clamping voltage at 7.8 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 P6KE56HE3/54 datasheet, P6KE56HE3/54 pinout, P6KE56HE3/54 application, or P6KE56HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.103 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 47.8 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the line to ≤77.0 V at 7.8 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
The P6KE56HE3/54 is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), dissipates 5.0 W on infinite heatsink at 75 °C lead temperature, and exhibits 20 °C/W typical junction-to-lead thermal resistance - enabling robust thermal performance in compact PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V at 1.0 mA test current - defines precise triggering threshold for overvoltage events |
| VWM | 47.8 V - maximum continuous working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 77.0 V at 7.8 A peak pulse current - limits protected circuit voltage during 600 W transient |
| PPPM | 600 W with 10/1000 µs waveform - sustains high-energy surges common in automotive load dump |
| TJ max | 175 °C - supports operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with automated through-hole assembly |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | Surface-mount SMB package; 58 V VBR; 600 W rating; 100 A IFSM; same VC = 93.6 V at 6.4 A | Requires SMT reflow process; smaller footprint but lower thermal mass than DO-15 | Select for space-constrained PCBs where automated assembly and higher board density are prioritized |
| 1.5KE56A | Same DO-204AC package; 56 V VBR; 1500 W PPPM; VC = 93.6 V at 16.1 A; no AEC-Q101 qualification | Higher surge capacity but lacks automotive qualification and has higher clamping voltage | Select for non-automotive industrial applications requiring greater single-pulse energy absorption |
Compared with SMBJ58A and 1.5KE56A, the P6KE56HE3/54 uniquely combines AEC-Q101 qualification, axial through-hole assembly compatibility, and optimized clamping performance (77.0 V) for cost-sensitive automotive and industrial designs where reliability and legacy manufacturing processes matter.

FAQ
What is the clamping voltage of P6KE56HE3/54 and how is it measured?
The P6KE56HE3/54 has a maximum clamping voltage (VC) of 77.0 V at 7.8 A peak pulse current, tested with a 10/1000 µs waveform per Fig. 1 in Vishay document 88369. This value represents the upper voltage limit imposed on the protected line during a standardized surge event and is critical for ensuring downstream ICs remain within absolute maximum ratings. The P6KE56HE3/54 achieves this clamping performance while maintaining low incremental surge resistance.
Is P6KE56HE3/54 suitable for automotive applications?
Yes, the P6KE56HE3/54 is AEC-Q101 qualified (as indicated by the HE3 suffix), meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD required for automotive electronics. Its 175 °C maximum junction temperature, robust glass-passivated junction, and DO-204AC mechanical construction make it appropriate for engine control units, body control modules, and infotainment power supplies where reliability under thermal and electrical stress is mandatory. The P6KE56HE3/54 meets these requirements without derating.
How does the HE3 suffix differ from E3 in P6KE56HE3/54?
The HE3 suffix on P6KE56HE3/54 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS compliance and JESD 201 Class 1A whisker resistance only. Both meet UL 94 V-0 flammability and matte tin plating per J-STD-002, but HE3 adds automotive-grade reliability validation - including extended temperature cycling and high-temperature operating life testing - making P6KE56HE3/54 suitable for safety-critical vehicle subsystems where the base P6KE56E3/54 would not be approved.
What is the thermal resistance of P6KE56HE3/54 and why does it matter?
The P6KE56HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard test conditions. This parameter determines how effectively heat generated during surge conduction transfers from the silicon die to the PCB copper via the leads. A lower RθJL enables higher repetitive surge capability and improves long-term reliability in thermally constrained environments - especially important in automotive under-hood applications where ambient temperatures exceed 105 °C and the P6KE56HE3/54 must sustain repeated transients without thermal runaway.
Can P6KE56HE3/54 be used for bi-directional protection?
No, P6KE56HE3/54 is a uni-directional TVS diode, as confirmed by its part number suffix "A" (not "CA") and specification table entries showing VBR and VWM only for reverse bias. Bi-directional variants like P6KE56CA exist but have different breakdown symmetry and no cathode marking. Using P6KE56HE3/54 in bi-directional configurations risks forward conduction during negative transients, potentially damaging the device or failing to protect. For AC or dual-polarity lines, select a CA-suffixed variant or pair of uni-directional devices - never substitute P6KE56HE3/54 for bi-directional duty.
