Product details
Overview
P4KE62CHE3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA test current, 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE62CHE3/73 datasheet, P4KE62CHE3/73 pinout, P4KE62CHE3/73 application, or P4KE62CHE3/73 equivalent, key selection criteria include verified clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, DO-41 mechanical compatibility, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design.
Technical Context
This device operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its specified VBR range (58.9–65.1 V). Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance, critical for repeatable transient suppression across temperature.
It delivers 400 W peak pulse power handling per 10/1000 μs waveform with 0.01 % duty cycle, and exhibits 1.5 W steady-state power dissipation on infinite heatsink at TL = 75 °C. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC/AC working margin. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 85.0 V at IPPM = 4.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W - Sustained transient energy absorption capability per standardized waveform; validates compliance with IEC 61000-4-5 Level 3/4. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Low off-state current minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | 175 °C - Maximum junction temperature rating supports operation in under-hood automotive and industrial environments. |
| RθJL | 66 °C/W - Thermal resistance from junction to lead enables accurate PCB copper pour sizing for thermal management. |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with glass-passivated chip junction; matte tin-plated leads; RoHS-compliant and AEC-Q101 qualified (HE3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); conducts during forward surge or bias conditions. |
| Cathode (marked with band) | Reverse breakdown terminal | 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 and long-term reliability under thermal cycling and humidity exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | DO-214AA package; 60 V VWM; 66.7–73.7 V VBR; 96.8 V VC at 4.1 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB layout revision | Select SMBJ60A only if higher surge margin (>400 W) is required and DO-214AA space is available. |
| 1.5KE62A | DO-201AD package; identical VWM/VBR/VC specs; same 400 W rating; non-AEC-Q101 rated | Lacks automotive qualification; suitable for commercial/industrial use only | Choose 1.5KE62A where AEC-Q101 is not mandated and legacy DO-201AD footprint must be retained. |
Compared with SMBJ60A and 1.5KE62A, P4KE62CHE3/73 uniquely combines AEC-Q101 qualification, DO-41 compactness, and verified 400 W clamping performance - making it optimal for space-constrained automotive modules requiring zero-retest validation.

FAQ
What is the clamping voltage of P4KE62CHE3/73 under a 10/1000 μs surge?
The P4KE62CHE3/73 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM), measured using the standard 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88365, Rev. 16-Sep-2021) and defines the upper voltage limit imposed on protected circuitry during surge events. Designers use this parameter to verify that downstream ICs remain within their absolute maximum ratings.
Is P4KE62CHE3/73 qualified for automotive applications?
Yes, P4KE62CHE3/73 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and explicit note in the Vishay datasheet (Section "MECHANICAL DATA"). This qualification covers stress tests including temperature cycling, humidity bias HAST, and mechanical shock - validating its use in engine control, body electronics, and ADAS sensor modules where reliability under vibration and thermal extremes is mandatory.
What does the "HE3" suffix indicate in P4KE62CHE3/73?
The "HE3" suffix in P4KE62CHE3/73 denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this variant from commercial-grade "E3" versions (e.g., P4KE62AE3/73), confirming enhanced process controls for automotive deployment. The "73" indicates packaging in 13″ paper tape and reel, quantity 5500 units per reel.
How does P4KE62CHE3/73 differ from P4KE62A?
P4KE62CHE3/73 is the AEC-Q101 qualified, RoHS-compliant version of the base P4KE62A, with identical electrical specs (VWM = 53.0 V, VBR = 58.9–65.1 V, VC = 85.0 V) but stricter process controls, whisker-tested leads (JESD 201 Class 2), and traceable lot documentation. The "H" prefix explicitly signals automotive qualification - critical for Tier 1 supplier audits and PPAP submissions.
What is the thermal resistance of P4KE62CHE3/73, and why does it matter?
P4KE62CHE3/73 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, per Vishay's thermal characteristics table. This value enables accurate calculation of junction temperature rise under pulsed or continuous power dissipation, guiding PCB copper pour design and ensuring operation remains within the 175 °C maximum junction limit - especially vital in sealed automotive enclosures with limited airflow.
