Product details
Overview
P6KE62HE3/73 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 62 V breakdown voltage (VBR min = 58.9 V, max = 65.1 V), 85 V maximum clamping voltage at 7.1 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients.
For engineers reviewing the P6KE62HE3/73 datasheet, P6KE62HE3/73 pinout, P6KE62HE3/73 application, or P6KE62HE3/73 equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, 53.0 V stand-off voltage (VWM), ≤1.0 µA reverse leakage at VWM, -55 °C to +175 °C operating junction temperature, and verified surge robustness per IEC 61000-4-5 Level 4 requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 GΩ) below VWM = 53.0 V, then rapidly avalanches into low-impedance conduction when transient voltage exceeds VBR (58.9–65.1 V @ 1.0 mA). Its glass-passivated junction ensures stable breakdown characteristics and fast response (<1 ns).
Thermal design relies on RθJL = 20 °C/W (junction-to-lead) and RθJA = 75 °C/W (junction-to-ambient); derating begins above TA = 25 °C per Figure 2, with full 600 W capability only at TL ≤ 75 °C. The device fails short-circuit under catastrophic overload, enabling fuse or breaker coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V @ 1.0 mA - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 53.0 V - maximum continuous working voltage; system DC rail must stay ≤ this to avoid leakage-induced power loss |
| VC @ IPPM | 85.0 V @ 7.1 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum stress level |
| IPPM | 7.1 A - peak pulse current handling at rated waveform; sets minimum series impedance needed for coordination |
| PPPM | 600 W - transient energy absorption capacity; enables protection against 100 V/10 Ω IEC 61000-4-5 surges |
| TJ max | +175 °C - extended thermal range supports under-hood automotive placement without derating penalty |
| Leakage @ VWM | ≤1.0 µA - negligible standby current draw; critical for battery-powered sensor nodes and low-power MCU rails |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case meeting UL 94 V-0; matte tin-plated leads compliant with J-STD-002/JESD 22-B102 solderability; HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-potential node; completes shunt path during transient |
| Cathode (banded end) | High-side transient sensing node | Connected to protected line (e.g., 48 V rail or CAN_H); color band identifies polarity for uni-directional operation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable VBR tolerance (±5 %) and long-term reliability under thermal cycling and humidity |
| 600 W peak pulse power (10/1000 µs) | Withstands repeated 1 kV/500 Ω IEC 61000-4-5 surges without degradation in automotive body control modules |
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and infotainment power supplies |
| Fast response time <1 ns | Clamps before sensitive CMOS inputs (e.g., microcontroller GPIO) experience destructive overvoltage |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., ISO 7637-2 Pulse 1/2a), improving protection margin |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 12 V/24 V vehicle battery rail exposed to load dump (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Shunt clamping element placed between power input and ground, triggered within nanoseconds of overvoltage event. Use Value: Limits rail voltage to ≤85 V during 35 V/100 ms load dump, preventing damage to PMICs and MCU power domains. |
Use Scenario: 4–20 mA current loop transmitter connected to PLC analog input in factory automation. IC Role / Device Role / Timing Role: Primary protection on signal line against ESD (IEC 61000-4-2) and field-wiring induced surges. Use Value: Clamps transients to <85 V while maintaining ≤1 µA leakage at 24 V nominal, preserving loop accuracy and calibration stability. |
| Consumer Device USB Port Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: VBUS line of USB 2.0 host port in set-top box or gaming console subjected to hot-plug ESD. IC Role / Device Role / Timing Role: First-line defense parallel to port, conducting ESD current away from USB transceiver IC. Use Value: Responds in <1 ns to ±15 kV contact discharge, limiting voltage seen by USB PHY to safe levels without affecting signal integrity. |
Use Scenario: Tip/ring lines of POTS interface on VoIP gateway exposed to lightning-induced surges per GR-1089-CORE. IC Role / Device Role / Timing Role: Standoff-rated protector on line side of transformer, coordinated with gas discharge tube (GDT) secondary stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | DO-214AA package; 60 V VBR (min 57 V); 6.5 A IPPM; 600 W rating; same VC = 96.8 V | Surface-mount footprint; higher thermal resistance (RθJA ≈ 110 °C/W) limits high-duty-cycle use | Select SMBJ60A for space-constrained PCBs where reflow assembly is required and thermal mass is sufficient. |
| 1.5KE62A | Same DO-204AC package; identical VBR (58.9–65.1 V); 600 W rating; but commercial-grade (non-AEC-Q101) | Lacks automotive qualification; lower whisker resistance (JESD 201 Class 1A vs. Class 2) | Choose 1.5KE62A for cost-sensitive industrial or consumer applications where AEC-Q101 is not mandated. |
Compared with SMBJ60A and 1.5KE62A, P6KE62HE3/73 uniquely combines AEC-Q101 qualification, axial-leaded DO-15 compatibility for through-hole reliability, and optimized thermal performance (RθJL = 20 °C/W) - making it preferred for mission-critical automotive and industrial power entry points.

FAQ
What is the maximum clamping voltage of the P6KE62HE3/73 under standard test conditions?
The P6KE62HE3/73 has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current (IPPM = 7.1 A) using the 10/1000 µs waveform. This value is measured per JEDEC standards and represents the upper limit of voltage imposed on the protected circuit during worst-case surge events - critical for ensuring downstream components like 75 V-rated MOSFETs remain within safe operating area.
Is the P6KE62HE3/73 suitable for automotive applications?
Yes, the P6KE62HE3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its -55 °C to +175 °C operating junction temperature range, JESD 201 Class 2 whisker resistance, and validation against load dump (ISO 16750-2) and ESD (ISO 10605) make it appropriate for engine control units, body electronics, and ADAS power supplies - unlike commercial-grade variants such as P6KE62A.
How does the P6KE62HE3/73 differ from the P6KE62A variant?
The P6KE62HE3/73 differs from P6KE62A primarily in qualification and plating: the HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas P6KE62A is commercial-grade with Class 1A plating. Both share identical electrical specs (VBR, VC, PPPM) and DO-204AC packaging, but only P6KE62HE3/73 meets automotive reliability requirements for long-life, high-vibration deployments.
What is the stand-off voltage (VWM) of the P6KE62HE3/73, and why does it matter?
The stand-off voltage (VWM) of the P6KE62HE3/73 is 53.0 V - the maximum continuous DC or RMS voltage that can be applied without exceeding 1.0 µA reverse leakage. This parameter ensures the device remains non-conductive during normal operation, avoiding power loss or false triggering on 48 V systems; selecting a TVS with VWM > system nominal voltage is essential for reliable standby behavior.
Can the P6KE62HE3/73 be used in bi-directional configurations?
No, the P6KE62HE3/73 is a uni-directional TVS diode, indicated by the "A" suffix and cathode band marking. For bi-directional protection (e.g., AC lines or differential data buses), Vishay offers the P6KE62CA variant - which has symmetric breakdown in both polarities and no polarity marking. Using P6KE62HE3/73 in reverse-biased AC applications would result in forward conduction and failure.
