Product details
Overview
P6KE170-E3/54 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 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 power supply inputs, industrial motor drive control circuits, and telecom line interface protection.
For engineers reviewing the P6KE170-E3/54 datasheet, P6KE170-E3/54 pinout, P6KE170-E3/54 application, or P6KE170-E3/54 equivalent, this device delivers verified AEC-Q101-qualified surge immunity, DO-15 package compatibility with standard through-hole PCB layouts, and precise clamping performance critical for protecting MOSFET gate drivers, microcontroller I/O, and sensor front-ends against inductive switching transients and ESD events.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: when reverse-biased voltage exceeds VBR, it avalanches into low-impedance conduction to divert transient energy away from downstream components. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM = 145 V).
Thermal design is enabled by RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient), supporting reliable operation up to TJ = 175 °C. The 100 A IFSM rating (8.3 ms half-sine) confirms robustness against repetitive surge events in industrial power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V - defines guaranteed avalanche initiation range under 1 mA test current; ensures consistent turn-on across temperature and unit variation |
| VWM | 145 V - maximum continuous reverse operating voltage; sets safe DC bias margin before leakage rises above 1 µA |
| VC @ IPPM | 234 V at 2.6 A - clamping voltage during 10/1000 µs transient; determines worst-case overvoltage seen by protected IC |
| PPPM | 600 W - peak pulse power handling per single 10/1000 µs event; supports protection against IEC 61000-4-5 Level 4 surges |
| IFSM | 100 A - non-repetitive forward surge current rating (8.3 ms); validates survivability during accidental polarity reversal or high-energy faults |
| TJ max | 175 °C - maximum junction temperature; enables use in under-hood automotive and high-ambient industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with 0.300" lead spacing; compatible with wave soldering (275 °C, 10 s) |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with matte tin-plated leads; cathode indicated by color band on body end. Leads meet J-STD-002 and JESD 22-B102 solderability standards; E3 suffix complies with JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration; carries full surge current during clamping |
| Cathode | Avalanche conduction terminal | Marked end of device; connected to protected line (e.g., +12 V rail); initiates clamping when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %), low leakage (<1 µA), and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 µs) | Validated capability to absorb IEC 61000-4-5 Combination Wave surges up to 4 kV (open-circuit) without degradation |
| AEC-Q101 qualified (E3 suffix variant) | Meets automotive-grade stress testing including HTOL, TC, UHAST, and ESD-HBM ≥ 8 kV - suitable for engine control and ADAS power domains |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage overshoot during fast transients, reducing risk of latch-up or oxide breakdown in protected CMOS devices |
| RoHS-compliant, halogen-free molding compound | UL 94 V-0 rated epoxy meets environmental compliance for consumer, industrial, and automotive end equipment |
Applications
| Automotive Power Input Protection | Industrial Motor Drive Control |
|---|---|

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 | Same VBR (162–179 V), but SMC (DO-214AB) surface-mount package; 600 W rating; slightly higher VC (243 V) | Requires PCB redesign for SMT placement; better thermal dissipation in high-density layouts; not axial-leaded | Select SMBJ170A when board space is constrained and reflow assembly is used; avoid if through-hole manufacturing is fixed. |
| 1.5KE170A | Same DO-15 package and VBR, but 1500 W peak power (10/1000 µs); larger die; higher IPPM (8.2 A); same VC (234 V) | Overqualified for 600 W needs; higher cost and larger junction capacitance may affect high-speed signal lines | Choose 1.5KE170A only when legacy designs require backward-compatible footprint with enhanced surge margin beyond IEC 61000-4-5 Level 4. |
Compared with SMBJ170A and 1.5KE170A, P6KE170-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, and precise 600 W surge handling - making it the preferred choice for cost-sensitive, high-volume automotive and industrial through-hole applications where exact power rating alignment matters.

FAQ
What is the breakdown voltage tolerance for P6KE170-E3/54?
The P6KE170-E3/54 has a specified breakdown voltage range of 162 V to 179 V at 1 mA test current (VBR min/max), corresponding to ±5 % tolerance around the nominal 170 V rating. This tight tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with downstream overvoltage lockout thresholds in power management ICs.
Is P6KE170-E3/54 suitable for automotive applications?
Yes, the P6KE170-E3/54 is AEC-Q101 qualified (per Vishay documentation), confirming its suitability for automotive powertrain and body electronics. Its 175 °C maximum junction temperature, robust surge ratings, and RoHS/halogen-free construction meet requirements for under-hood and cabin-mounted ECUs - provided layout adheres to thermal derating curves in the datasheet.
What is the clamping voltage of P6KE170-E3/54 at its rated peak pulse current?
The P6KE170-E3/54 clamps to a maximum of 234 V at its rated peak pulse current of 2.6 A (10/1000 µs waveform). This value is measured under standardized conditions and represents the worst-case overvoltage imposed on protected circuitry during a full-rated surge event - essential for verifying margin against downstream component absolute maximum ratings.
How does the P6KE170-E3/54 differ from bi-directional variants like P6KE170CA?
The P6KE170-E3/54 is unidirectional, with a cathode band marking and forward voltage drop (~5.0 V at 50 A), intended for DC rail protection where polarity is fixed. In contrast, P6KE170CA is bi-directional, lacks polarity marking, and suppresses transients in both directions - making it suitable for AC lines or differential signal pairs, but with different VBR and VC specifications.
What package and lead finish does P6KE170-E3/54 use?
P6KE170-E3/54 uses the DO-204AC (DO-15) axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. The E3 suffix indicates RoHS compliance and JESD 201 Class 1A whisker resistance, enabling reliable wave soldering at 275 °C for 10 seconds without lead degradation.
