Product details
Overview
P6KE15HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 15 V breakdown voltage (VBR = 14.3–15.8 V at 1.0 mA), 21.2 V maximum clamping voltage (VC) at 28.3 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the P6KE15HE3/73 datasheet, P6KE15HE3/73 pinout, P6KE15HE3/73 application, or P6KE15HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, 12.8 V stand-off voltage (VWM), <1.0 µA reverse leakage at VWM, and thermal resistance of 20 °C/W (junction-to-lead) - all critical for reliability-critical 12 V automotive subsystems and industrial I/O protection.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<1.0 µA leakage at 12.8 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, clamping the line to ≤21.2 V at 28.3 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns).
Designed for single-pulse and low-duty-cycle surge events, it supports repetitive surges up to 0.01 % duty cycle and withstands 100 A non-repetitive forward surge (8.3 ms half-sine). The device's thermal design relies on lead-to-board heat transfer, with RθJL = 20 °C/W enabling effective power dissipation without heatsinking in PCB-mounted applications.
Key Specifications

|---|---|
| VBR (min/max) | 14.3 V / 15.8 V at 1.0 mA - defines precise triggering threshold for overvoltage detection |
| VWM | 12.8 V - maximum continuous working voltage before leakage rises above 1.0 µA |
| VC @ IPPM | 21.2 V at 28.3 A (10/1000 µs) - clamping level protecting downstream 15 V-rated components |
| PPPM | 600 W - surge energy handling capacity compatible with ISO 7637-2 Pulse 1/2a/5a test profiles |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V battery-fed ECUs exposed to ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump). IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between power rail and chassis ground, triggered within <1 ns to clamp transients below 22 V. Use Value: Prevents latch-up or gate oxide rupture in MCU power supplies and CAN transceivers operating at 12 V nominal. |
Use Scenario: 4–20 mA current loop sensors in factory automation subject to field wiring ESD and motor drive coupling. IC Role / Device Role / Timing Role: Uni-directional TVS mounted across sensor output terminals to divert ±8 kV contact ESD (IEC 61000-4-2) and 400 V ring wave surges. Use Value: Maintains signal integrity by limiting voltage excursion to <22 V, preserving analog front-end accuracy and preventing ADC saturation. |
| DC Motor Driver Gate Protection | Power Supply Input Stage Clamping |
|
Use Scenario: N-channel MOSFET half-bridge drivers in BLDC controllers subjected to back-EMF spikes during commutation. IC Role / Device Role / Timing Role: Placed anode-to-source, cathode-to-drain to clamp inductive kickback and prevent VDS overstress beyond rated breakdown. Use Value: Enables use of lower RDS(on) MOSFETs by absorbing 600 W transient energy without external snubbers. |
Use Scenario: Input stage of 12 V wall adapter or PoE-powered device encountering lightning-induced surges on AC/DC input lines. IC Role / Device Role / Timing Role: First-line defense upstream of rectifier and bulk capacitor, clamping differential-mode transients before they reach primary-side controller. Use Value: Reduces required Y-capacitor size and eliminates need for MOV-based secondary-stage clamping in cost-sensitive consumer power supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5BT | Same VBR range (14.3–15.8 V), but SMA package (surface-mount); lower PPPM = 400 W | Preferred for space-constrained PCBs; unsuitable for high-energy load-dump events requiring 600 W | Select when board area is limited and surge energy is ≤400 W (e.g., USB-C PD port protection) |
| 1.5KE15A | Same DO-15 package and 600 W rating, but commercial-grade (non-AEC-Q101); higher leakage (5.0 µA vs. 1.0 µA) | Acceptable for industrial controls without automotive qualification requirements | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
Compared with SMAJ15A-E3/5BT and 1.5KE15A, P6KE15HE3/73 uniquely combines AEC-Q101 qualification, 600 W capability in DO-15, and sub-µA leakage - making it the only option qualified for under-hood automotive power rail protection without layout or thermal redesign.

FAQ
What is the clamping voltage of P6KE15HE3/73 and how does it protect downstream components?
The P6KE15HE3/73 clamps to a maximum of 21.2 V at 28.3 A (10/1000 µs waveform). This limits transient overvoltage seen by connected ICs or MOSFETs to a safe margin below their absolute maximum ratings - for example, preserving 24 V-tolerant microcontrollers or 30 V-rated gate drivers during load-dump events. Its low clamping ratio (VC/VBR ≈ 1.39) ensures minimal voltage overshoot during fast-rising transients.
Is P6KE15HE3/73 suitable for automotive applications, and what qualifications does it hold?
Yes, P6KE15HE3/73 is AEC-Q101 qualified - verified for automotive use via high-temperature reverse bias (HTRB), temperature cycling, and ESD testing per JESD22-A114 (≥8 kV HBM). The HE3 suffix confirms RoHS compliance and JESD201 Class 2 whisker resistance, making P6KE15HE3/73 appropriate for engine control modules, body electronics, and ADAS power domains.
How does the DO-204AC (DO-15) package of P6KE15HE3/73 impact thermal performance?
The DO-204AC package delivers RθJL = 20 °C/W (junction-to-lead), enabling efficient heat transfer to PCB copper lands. With a 5.0 W steady-state power dissipation rating at TL = 75 °C, P6KE15HE3/73 sustains repeated surge events without thermal runaway when mounted on ≥100 mm² 2-oz copper pads - eliminating need for heatsinks in most 12 V automotive and industrial applications.
What is the difference between P6KE15HE3/73 and P6KE15A-E3/73?
P6KE15HE3/73 is AEC-Q101 qualified and meets JESD201 Class 2 whisker resistance, while P6KE15A-E3/73 is commercial-grade (Class 1A whisker test). Both share identical electrical specs (VBR, VC, PPPM), but P6KE15HE3/73 undergoes extended reliability stress screening - making it mandatory for automotive Tier-1 suppliers and preferred for industrial equipment requiring long-term field reliability.
Can P6KE15HE3/73 be used in bi-directional protection circuits?
No - P6KE15HE3/73 is strictly uni-directional, with cathode marked by a band. For bi-directional protection (e.g., AC lines or differential data buses), the CA-suffixed variant P6KE15CA must be used. Using P6KE15HE3/73 in reverse-biased configurations risks permanent breakdown due to lack of symmetrical avalanche structure.
