Product details
Overview
P6KE170HE3/54 from Vishay General Semiconductor is a unidirectional 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 170 V breakdown voltage (VBR min/max = 162–179 V), 145 V standoff voltage (VWM), 234 V 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 ECU power inputs and industrial sensor interface protection.
For engineers reviewing the P6KE170HE3/54 datasheet, P6KE170HE3/54 pinout, P6KE170HE3/54 application, or P6KE170HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C maximum junction temperature, low 0.108 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability standards.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), then rapidly avalanches below 10 ns to clamp transient energy when voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for single-polarity DC systems, P6KE170HE3/54 is rated for 100 A non-repetitive forward surge current (IFSM) and exhibits 3.5 V max forward voltage at 50 A. Thermal resistance is 20 °C/W junction-to-lead and 75 °C/W junction-to-ambient, enabling reliable operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V at 1 mA test current - defines precise avalanche initiation window for predictable clamping onset |
| VWM | 145 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 234 V at 2.6 A (10/1000 µs) - maximum clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 600 W - peak transient power handling capability under standardized surge waveform |
| IFSM | 100 A - withstands 8.3 ms half-sine surge without failure, critical for load-dump protection |
| TJ max | 175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| Temp. Coeff. (VBR) | +0.108 %/°C - quantifies VBR drift over temperature, essential for precision rail protection design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A-E3/52 | Same VBR range (162–179 V), but SMC (DO-214AB) package; 600 W rating, 234 V VC, higher IPPM (2.6 A vs. 2.6 A - identical), but lower thermal resistance (RθJA = 40 °C/W vs. 75 °C/W). | Surface-mount alternative requiring PCB redesign; better suited for automated assembly and higher power density layouts. | Select SMBJ170A-E3/52 when space-constrained SMT layout and improved thermal performance are prioritized over through-hole serviceability. |
| 1.5KE170A | Same DO-204AC package and VBR spec, but 1.5 kW peak power (10/1000 µs); VC = 274 V at 5.5 A; not AEC-Q101 qualified; commercial grade only. | Larger surge margin for non-automotive industrial applications where higher clamping voltage is acceptable. | Choose 1.5KE170A only for cost-sensitive, non-automotive designs needing >600 W headroom and no AEC-Q101 requirement. |
Compared with SMBJ170A-E3/52, P6KE170HE3/54 offers proven through-hole robustness and AEC-Q101 validation for harsh environments; versus 1.5KE170A, it trades peak power for tighter clamping and automotive qualification - making it optimal for safety-critical 12/24 V embedded systems.

FAQ
What is the clamping voltage of P6KE170HE3/54 and how is it measured?
The clamping voltage (VC) of P6KE170HE3/54 is 234 V, measured at a peak pulse current (IPPM) of 2.6 A using the standardized 10/1000 µs double-exponential waveform. This value represents the maximum voltage that appears across the device terminals during a surge event, directly limiting stress on downstream components. The specification is guaranteed per Vishay document 88369 and applies at TA = 25 °C.
Is P6KE170HE3/54 suitable for automotive applications?
Yes, P6KE170HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body control modules, and ADAS power domains. Its 175 °C maximum junction temperature, glass-passivated junction, and robust surge ratings meet requirements for under-hood and chassis-mounted electronics per ISO 16750-2 and ISO 7637-2.
What does the 'HE3' suffix indicate in P6KE170HE3/54?
The 'HE3' suffix in P6KE170HE3/54 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade variant from the commercial 'E3' version (e.g., P6KE170A-E3/54), confirming enhanced reliability testing and material compliance for mission-critical applications.
How does P6KE170HE3/54 differ from bi-directional P6KE170CA variants?
P6KE170HE3/54 is unidirectional, with a cathode band marking and forward conduction capability; P6KE170CA is bi-directional, symmetric in both polarities and unmarked. The unidirectional version provides lower forward voltage (3.5 V at 50 A) and is used on DC rails where polarity is fixed, whereas the CA variant suits AC-coupled or floating signal lines.
What is the thermal resistance of P6KE170HE3/54 and why does it matter?
P6KE170HE3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. These values determine how effectively heat generated during surge events dissipates - critical for sustained reliability in high-temperature environments like automotive under-hood locations or enclosed industrial controllers.
