Product details
Overview
P6KE170AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 170 V breakdown voltage (VBR min/max = 162–179 V), 145 V stand-off voltage (VWM), 234 V maximum clamping voltage at 2.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive ECUs, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the P6KE170AHE3/54 datasheet, P6KE170AHE3/54 pinout, P6KE170AHE3/54 application, or P6KE170AHE3/54 equivalent, this device delivers AEC-Q101 qualified surge immunity, DO-15 package compatibility with legacy board layouts, low incremental surge resistance, and verified clamping performance under repetitive 0.01% duty-cycle transients - critical for ESD and load-dump hardened designs.
Technical Context
The P6KE170AHE3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its unidirectional polarity uses a cathode band marking, and it sustains 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave while maintaining thermal resistance of 20 °C/W (junction-to-lead).
Clamping behavior is characterized by a maximum VC = 234 V at IPPM = 2.6 A (10/1000 µs), with temperature coefficient of VBR at +0.108 %/°C. It exhibits 1.0 µA max reverse leakage at VWM = 145 V and operates across -55 °C to +175 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V - defines guaranteed avalanche conduction onset window under 1.0 mA test current |
| VWM | 145 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 234 V @ 2.6 A - clamped voltage during 10/1000 µs surge, limiting downstream component stress |
| PPPM | 600 W - peak transient power handling capability, derated linearly above 25 °C ambient |
| IFSM | 100 A - withstands single 8.3 ms half-sine surge without failure, critical for automotive load dump |
| TJ max | +175 °C - enables operation in high-temperature engine bay or industrial enclosures |
| RθJL | 20 °C/W - low thermal resistance supports reliable power dissipation into PCB copper or lead frame |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | DO-214AA package; 170 V VBR; 235 V VC @ 2.5 A; 600 W rating; surface-mount only | Requires PCB redesign for SMD placement; better thermal performance in high-density layouts | Select SMBJ170A when space-constrained designs demand SMT assembly and improved power density. |
| 1.5KE170A | Same DO-15 package; 170 V VBR; 274 V VC @ 2.2 A; 1500 W rating; higher clamping voltage and larger surge capacity | Higher VC may exceed downstream component ratings; suited for less sensitive circuits with higher margin | Choose 1.5KE170A where higher surge energy (e.g., ISO 7637-2 Pulse 5a) must be absorbed and VC margin allows. |
Compared with SMBJ170A and 1.5KE170A, the P6KE170AHE3/54 offers optimal balance of low clamping voltage, AEC-Q101 qualification, and through-hole manufacturability - making it preferred for cost-sensitive, high-reliability automotive and industrial replacements where layout change is prohibited.

FAQ
What is the maximum clamping voltage of the P6KE170AHE3/54 under standard test conditions?
The P6KE170AHE3/54 has a maximum clamping voltage (VC) of 234 V when subjected to a 10/1000 µs waveform peak pulse current of 2.6 A. This value is measured per JEDEC standards and reflects worst-case let-through voltage during surge events - critical for ensuring downstream components remain within their absolute maximum ratings. The P6KE170AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE170AHE3/54 qualified for automotive applications?
Yes, the P6KE170AHE3/54 carries the HE3 suffix, indicating full AEC-Q101 qualification per Rev. 27-Sep-2021 documentation. It has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for under-hood and chassis-mounted automotive electronics. The P6KE170AHE3/54 is commonly used in engine control units and body control modules.
How does the P6KE170AHE3/54 differ from the commercial-grade P6KE170AE3/54?
The P6KE170AHE3/54 differs from P6KE170AE3/54 solely in qualification level: HE3 denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates commercial grade with JESD 201 Class 1A. Both share identical electrical parameters, DO-15 packaging, and thermal characteristics. The P6KE170AHE3/54 is required for automotive Tier 1 suppliers; P6KE170AE3/54 suffices for industrial or consumer applications.
What is the reverse leakage current specification for the P6KE170AHE3/54 at rated stand-off voltage?
At VWM = 145 V and TA = 25 °C, the P6KE170AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss in standby mode and prevents unintended biasing of sensitive analog circuits. Leakage remains below 5.0 µA up to 125 °C ambient, supporting reliable operation in thermally demanding environments where the P6KE170AHE3/54 is deployed.
Can the P6KE170AHE3/54 be used in bidirectional configurations?
No, the P6KE170AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). It conducts only in reverse bias above VBR and blocks forward current up to 3.5 V. For bidirectional protection, Vishay specifies variants like P6KE170CA - which lacks the cathode band and clamps symmetrically in both polarities. Using P6KE170AHE3/54 in AC or floating signal paths would result in forward conduction failure; always verify polarity marking before placement.
