Product details
Overview
P4KE82HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 V clamping voltage (VC) at 3.5 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines of automotive sensor units.
For engineers reviewing the P4KE82HE3/54 datasheet, P4KE82HE3/54 pinout, P4KE82HE3/54 application, or P4KE82HE3/54 equivalent, key selection criteria include AEC-Q101 qualification, DO-41 mechanical compatibility, unidirectional polarity with cathode band marking, and thermal resistance (RθJL = 66 °C/W) for board-level thermal design.
Technical Context
This device operates as a voltage-clamping protector: under normal conditions it presents high impedance (≤1.0 μA reverse leakage at 70.1 V), then rapidly switches to low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤113 V. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Rated for 175 °C maximum junction temperature and qualified per AEC-Q101, the P4KE82HE3/54 supports automotive-grade reliability. Its 1.5 W steady-state power dissipation (at TL = 75 °C) and 40 A 8.3 ms forward surge capability enable robust protection in inductive load switching environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 77.9 V / 86.1 V - defines minimum and maximum voltage at which device enters avalanche conduction during transient events |
| VWM | 70.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 113 V at 3.5 A - clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 400 W - peak transient power handling capacity under standardized 10/1000 μs waveform |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB copper pour sizing and thermal relief design |

Applications
| Automotive Sensor Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between sensor output and microcontroller ADC input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ80A | DO-214AA package (SMB), 80 V VWM, 125 V VC @ 3.2 A, same 400 W rating | Surface-mount footprint; higher mounting density but requires reflow profile validation | Select SMBJ80A when board space is constrained and SMT assembly is preferred over through-hole DO-41. |
| 1.5KE82A | Same DO-41 package, 82 V nominal VBR, but 1.5 kW peak power (10/1000 μs), higher VC = 137 V | Higher energy handling for infrequent but severe transients; less precise clamping | Choose 1.5KE82A only if system-level testing confirms 137 V clamping is acceptable for downstream ICs. |
Compared with SMBJ80A and 1.5KE82A, the P4KE82HE3/54 offers AEC-Q101 qualification and tighter VC (113 V), making it optimal for automotive-specified designs where reliability and clamping precision are prioritized over peak energy capacity or footprint size.

FAQ
What is the breakdown voltage range of the P4KE82HE3/54?
The P4KE82HE3/54 has a guaranteed breakdown voltage (VBR) range of 77.9 V to 86.1 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range reflects manufacturing tolerance and ensures consistent clamping behavior across production lots while allowing design margin for worst-case transient scenarios.
Is the P4KE82HE3/54 suitable for automotive applications?
Yes, the P4KE82HE3/54 is AEC-Q101 qualified and manufactured with HE3 suffix indicating compliance with JESD 201 Class 2 whisker testing. Its 175 °C maximum junction temperature, glass-passivated junction, and DO-41 mechanical robustness make it suitable for under-hood and body-control module applications where reliability under thermal and vibration stress is required.
How does the clamping voltage of P4KE82HE3/54 compare to its breakdown voltage?
The P4KE82HE3/54 clamps at 113 V when subjected to its rated 3.5 A peak pulse current (10/1000 μs), which is approximately 31 % above its minimum breakdown voltage of 77.9 V. This VC/VBR ratio reflects low dynamic impedance and effective transient suppression - critical for protecting downstream 75 V-rated components.
What is the meaning of the "HE3/54" suffix in P4KE82HE3/54?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101 qualified construction with JESD 201 Class 2 whisker resistance; "/54" specifies the preferred package code for 13-inch paper tape and reel packaging containing 5500 units - standard for automated through-hole insertion equipment used in high-volume manufacturing.
Can P4KE82HE3/54 be used in bidirectional configurations?
No, the P4KE82HE3/54 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay specifies CA-suffix variants (e.g., P4KE82CA). Using P4KE82HE3/54 in reverse-biased AC applications would result in forward conduction and potential failure; always verify polarity during layout and assembly.
