Product details
Overview
P6KE170CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 170 V breakdown voltage (VBR min/max = 162 V / 179 V), 145 V standoff voltage (VWM), 234 V maximum clamping voltage at 2.6 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive sensor protection and industrial I/O interfaces.
For engineers reviewing the P6KE170CAHE3/54 datasheet, P6KE170CAHE3/54 pinout, P6KE170CAHE3/54 application, or P6KE170CAHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-15 mechanical data, clamping behavior under surge conditions, and direct alternatives for overvoltage protection design-in.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical breakdown and clamping characteristics across forward and reverse directions. Its glass-passivated junction enables fast response (<1 ns), low incremental surge resistance, and stable performance up to 175 °C junction temperature.
Rated for 600 W peak pulse power (10/1000 µs), it sustains repetitive surges at 0.01 % duty cycle and meets UL 497B recognition (QVGQ2). The device is AEC-Q101 qualified (HE3 suffix), RoHS compliant, and rated for 100 A non-repetitive forward surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V at 1.0 mA test current - defines reliable conduction onset under transient stress |
| VWM | 145 V - maximum continuous working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 234 V at 2.6 A - clamped voltage during full-rated 600 W surge, limiting downstream IC stress |
| PPPM | 600 W - peak transient energy absorption capability with standard 10/1000 µs waveform |
| TJ max | +175 °C - enables operation in under-hood automotive or high-ambient industrial environments |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.25" lead spacing, UL 94 V-0 molding |
| Qualification | AEC-Q101 qualified (HE3 suffix) - validated for automotive electronics reliability per stress test requirements |

| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes overvoltage exposure to protected ICs compared to higher-ratio suppressors |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170CA | DO-214AA package; lower 600 W rating but tighter VC (274 V @ 2.2 A); surface-mount | Preferred for space-constrained PCBs where reflow assembly is required | Select SMBJ170CA when board area is limited and SMT placement is mandatory. |
| 1.5KE170CA | Higher 1500 W rating; same DO-15 package; VC = 274 V @ 5.5 A; larger thermal mass | Better suited for high-energy industrial surges where 600 W is marginal | Choose 1.5KE170CA when system-level surge tests exceed IEC 61000-4-5 Level 4. |
Compared with P6KE170CAHE3/54, SMBJ170CA offers SMT compatibility at reduced surge margin, while 1.5KE170CA provides higher energy handling in the same through-hole footprint - enabling trade-offs between board density, cost, and surge robustness.

FAQ
What is the clamping voltage of P6KE170CAHE3/54 at its rated peak pulse current?
The P6KE170CAHE3/54 has a maximum clamping voltage (VC) of 234 V at its rated peak pulse current (IPPM) of 2.6 A, measured using the standard 10/1000 µs waveform. This value ensures protected circuits experience no more than 234 V during full-rated transient events, directly supporting design margin calculations for downstream ICs.
Is P6KE170CAHE3/54 suitable for automotive applications?
Yes, P6KE170CAHE3/54 is AEC-Q101 qualified (denoted by the HE3 suffix), meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per automotive reliability standards. Its DO-15 package and 175 °C max junction temperature make it appropriate for engine control units, body electronics, and sensor modules.
How does the CA suffix affect the functionality of P6KE170CAHE3/54?
The CA suffix in P6KE170CAHE3/54 indicates a bidirectional configuration: the device clamps voltage transients equally in both polarities, with identical VBR, VWM, and VC specifications for forward and reverse directions. This eliminates polarity concerns in AC-coupled or differential signal lines, unlike unidirectional (A-suffix) variants.
What is the standoff voltage (VWM) of P6KE170CAHE3/54, and why does it matter?
The standoff voltage (VWM) of P6KE170CAHE3/54 is 145 V - the maximum continuous DC or RMS voltage the device can withstand without exceeding 1.0 μA leakage current. This parameter ensures reliable operation under normal line conditions while allowing sufficient margin below VBR (162–179 V) to avoid false triggering during nominal operation.
Does P6KE170CAHE3/54 have UL recognition, and for which standard?
Yes, P6KE170CAHE3/54 carries Underwriters Laboratories recognition under UL 497B (file E136766) for protectors used in telecommunications and signal line applications. This certification validates its safety performance in surge protection circuits, including dielectric strength, flammability (UL 94 V-0), and long-term reliability under repeated transient stress.
