Product details
Overview
P4KE62CHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection with 62 V breakdown voltage (VBR min 58.9 V, max 65.1 V), 400 W peak pulse power (10/1000 μs), and clamping voltage of 85.0 V at 4.7 A IPPM. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power supplies.
For engineers reviewing the P4KE62CHE3/54 datasheet, P4KE62CHE3/54 pinout, P4KE62CHE3/54 application, or P4KE62CHE3/54 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, DO-41 mechanical data, thermal resistance (RθJL = 66 °C/W), and real-world clamping behavior under transient stress.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 58.9–65.1 V breakdown range at 1 mA test current. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing inductive switching spikes and lightning-induced transients on DC rails.
Rated for 400 W peak pulse power (10/1000 μs waveform, 0.01% duty cycle), it sustains 40 A non-repetitive forward surge (8.3 ms half-sine) and maintains stable operation from –55 °C to +175 °C junction temperature, with 1.5 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at 1 mA - defines precise overvoltage trip threshold for reliable protection activation |

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 VBR; 600 W PPPM; RθJL = 35 °C/W | Higher power density but larger footprint; requires PCB area redesign | Select SMBJ60A only if system demands >400 W surge handling and board space permits SMC/SMB package |
| 1.5KE62A | Same DO-41 package; identical VBR range; 1500 W PPPM; higher IPPM (24.2 A) | Over-spec'd for most 400 W use cases; higher cost and capacitance (≈100 pF vs. ~50 pF) | Choose 1.5KE62A only when legacy designs require backward compatibility with 1.5 kW surge standards |
Compared with SMBJ60A and 1.5KE62A, P4KE62CHE3/54 offers optimal balance of AEC-Q101 qualification, DO-41 footprint compatibility, 400 W capability, and low thermal resistance-making it ideal for space-constrained automotive and industrial modules where qualification and reliability outweigh raw power headroom.

FAQ
What is the breakdown voltage tolerance for P4KE62CHE3/54?
The P4KE62CHE3/54 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1 mA test current, representing ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 65 V-rated power FETs without premature conduction.
Is P4KE62CHE3/54 suitable for automotive applications?
Yes, P4KE62CHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-glass-passivated junction, DO-41 package with matte tin leads, and operation up to +175 °C junction temperature-meets requirements for engine bay, body control, and infotainment power rail protection per ISO 16750-2 and ISO 7637-2 standards.
What is the clamping voltage of P4KE62CHE3/54 under surge conditions?
The P4KE62CHE3/54 clamps to a maximum of 85.0 V at its rated peak pulse current of 4.7 A (10/1000 μs waveform). This VC value is measured under standardized transient conditions and defines the upper voltage limit imposed on protected circuits during surge events, directly determining safe operating margins for downstream components.
Does P4KE62CHE3/54 have bidirectional capability?
No, P4KE62CHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and presence of cathode band marking. Bidirectional variants (e.g., P4KE62CA) exist in the same family but are distinct part numbers; P4KE62CHE3/54 conducts only in reverse avalanche mode and must be oriented with cathode toward the protected line.
What packaging format is used for P4KE62CHE3/54?
P4KE62CHE3/54 is supplied in 13-inch diameter paper tape and reel packaging, with base quantity 5500 units per reel (package code "54"). The "HE3" suffix confirms RoHS compliance and AEC-Q101 qualification, while the DO-41 body meets UL 94 V-0 flammability requirements for safety-critical installations.
