Product details
Overview
P6KE56HE3/73 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 53.2 V minimum breakdown voltage (VBR), 47.8 V maximum stand-off voltage (VWM), 77.0 V clamping voltage (VC) at 7.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial I/O modules, and telecom power supplies.
For engineers reviewing the P6KE56HE3/73 datasheet, P6KE56HE3/73 pinout, P6KE56HE3/73 application, or P6KE56HE3/73 equivalent, this AEC-Q101 qualified TVS offers verified surge immunity for 12 V/24 V systems, validated clamping performance under repetitive transients, RoHS-compliant matte tin-plated leads, and thermal resistance (RθJL) of 20 °C/W for reliable PCB-level thermal management.
Technical Context
The P6KE56HE3/73 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-polar clamping action only in reverse-biased mode (uni-directional polarity). Its 10/1000 µs waveform response enables suppression of ESD, lightning-induced surges, and inductive switching spikes up to 7.8 A peak pulse current while maintaining low incremental surge resistance and fast sub-nanosecond turn-on.
Designed for operation across –55 °C to +175 °C junction temperature range, it leverages DO-204AC mechanical construction with UL 94 V-0 epoxy molding and JESD 22-B106 solderability (275 °C, 10 s). The HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - critical for automotive under-hood and chassis-mounted applications.
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 avalanche onset threshold for predictable triggering |
| VWM | 47.8 V maximum - ensures no conduction during normal 12 V/24 V rail operation with 10 % margin |
| VC @ IPPM | 77.0 V at 7.8 A - limits protected circuit voltage to safe level during worst-case transient |
| PPPM | 600 W - sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without degradation |
| IFSM | 100 A peak forward surge - handles accidental reverse-connection or fault currents |
| TJ max. | +175 °C - supports under-hood automotive environments and high-ambient industrial use |
| RθJL | 20 °C/W - enables direct PCB copper pour heat sinking without external heatsink |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case with UL 94 V-0 rating. Cathode indicated by color band on body; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during fault conditions when cathode is at higher potential |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates avalanche breakdown when voltage exceeds VBR, shunting surge to ground |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A | DO-214AA package, 58 V VBR min, 64.4 V VC @ 9.3 A, same 600 W rating | Surface-mount footprint; lower RθJA (50 °C/W vs. 75 °C/W) but requires reflow-compatible layout | Select SMBJ58A for space-constrained SMT designs where board real estate is limited and thermal vias are feasible. |
| 1.5KE56A | Same DO-204AC package, identical VBR/VC specs, but commercial-grade (non-AEC-Q101), no HE3 whisker rating | Lacks automotive qualification and JESD 201 Class 2 compliance; suitable for consumer/industrial only | Choose 1.5KE56A for cost-sensitive non-automotive applications where AEC-Q101 is not mandated. |
Compared with SMBJ58A and 1.5KE56A, the P6KE56HE3/73 uniquely combines AEC-Q101 qualification, axial-leaded DO-204AC compatibility, and JESD 201 Class 2 whisker resistance - making it the only option qualified for under-hood automotive deployment without layout redesign.

FAQ
What is the breakdown voltage tolerance for P6KE56HE3/73?
The P6KE56HE3/73 has a specified breakdown voltage range of 53.2 V to 58.8 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 56 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in 12 V and 24 V systems where precise overvoltage thresholds are critical.
Is P6KE56HE3/73 suitable for automotive under-hood applications?
Yes, the P6KE56HE3/73 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature, making it suitable for under-hood automotive applications such as engine control modules and transmission control units. Its HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance and RoHS requirements - key criteria for automotive-grade components.
How does the clamping voltage of P6KE56HE3/73 compare to its breakdown voltage?
The P6KE56HE3/73 clamps at 77.0 V when subjected to its rated 7.8 A peak pulse current (10/1000 µs), yielding a clamping ratio (VC/VBR(min)) of approximately 1.45. This ratio reflects the device's low dynamic impedance during surge events and ensures protected circuits remain within safe operating voltage limits relative to their absolute maximum ratings.
What is the maximum reverse leakage current for P6KE56HE3/73 at rated stand-off voltage?
At its maximum stand-off voltage of 47.8 V, the P6KE56HE3/73 exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C ambient temperature. This ultra-low leakage preserves system efficiency in always-on automotive modules and prevents unintended power drain in battery-backed industrial sensors.
Can P6KE56HE3/73 be used in bi-directional protection configurations?
No, the P6KE56HE3/73 is a uni-directional TVS diode, identified by its "A" suffix and cathode band marking. For bi-directional protection, Vishay specifies the "CA" suffix variant (e.g., P6KE56CA). Using P6KE56HE3/73 in AC or bidirectional signal paths would result in forward conduction during negative half-cycles, potentially damaging the device or circuit.
