Product details
Overview
P4KE82CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal and power lines. It features 77.9 V to 86.1 V breakdown voltage (VBR), 70.1 V standoff voltage (VWM), 113 A peak pulse current (IPPM), 400 W peak pulse power (10/1000 μs), and operates from –55 °C to +175 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE82CA-E3/54 datasheet, P4KE82CA-E3/54 pinout, P4KE82CA-E3/54 application, or P4KE82CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification, low leakage (<1.0 μA at 70.1 V), and thermal resistance (RθJL = 66 °C/W) for reliable transient energy dissipation in space-constrained PCB layouts.
Technical Context
This device implements a glass-passivated PN junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its bidirectional symmetry enables identical clamping behavior in both polarities without polarity marking, supporting AC-coupled lines and differential interfaces.
The 400 W peak pulse rating is defined per 10/1000 μs waveform with 0.01% duty cycle, and derating begins above 25 °C ambient per Fig. 2. Junction-to-lead thermal resistance of 66 °C/W allows direct soldering to copper pour for enhanced surge handling without heatsinking.
Key Specifications

FAQ
What is the breakdown voltage range of the P4KE82CA-E3/54?
The P4KE82CA-E3/54 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 production tolerance and ensures consistent clamping performance across units. The P4KE82CA-E3/54 maintains this specification under standard test conditions (TA = 25 °C) and is validated across its full operating temperature range.
Is the P4KE82CA-E3/54 suitable for automotive applications?
Yes, the P4KE82CA-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive modules. Its glass-passivated junction, low leakage (<1.0 μA at 70.1 V), and robust surge handling (400 W, 10/1000 μs) align with requirements for engine control units, ADAS sensors, and body electronics. The P4KE82CA-E3/54 meets these criteria without requiring derating in typical automotive thermal environments.
How does the bidirectional design of the P4KE82CA-E3/54 affect its use in circuit protection?
The bidirectional design of the P4KE82CA-E3/54 means it provides symmetrical clamping in both polarities, eliminating the need for polarity identification during placement and enabling use on AC signals, differential buses (e.g., RS-485), and ungrounded interfaces. Unlike unidirectional TVS diodes, the P4KE82CA-E3/54 has no cathode band marking and functions identically regardless of voltage polarity - simplifying layout and reducing BOM complexity in dual-rail or floating systems.
What is the maximum clamping voltage of the P4KE82CA-E3/54 during a surge event?
The P4KE82CA-E3/54 clamps to a maximum of 113 V when subjected to its rated 113 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This clamping voltage is measured at the device terminals and represents the upper limit of voltage imposed on protected circuitry during worst-case surge conditions. The P4KE82CA-E3/54 achieves this performance with minimal overshoot due to its low incremental surge resistance and sub-nanosecond response time.
Does the P4KE82CA-E3/54 require heatsinking for standard surge events?
No, the P4KE82CA-E3/54 does not require external heatsinking for single or repetitive 400 W surges (10/1000 μs, 0.01% duty cycle) due to its low junction-to-lead thermal resistance of 66 °C/W and optimized DO-41 package design. Heat is efficiently conducted through its leads into PCB copper pours. The P4KE82CA-E3/54 maintains safe junction temperatures under typical board layouts with ≥1 cm² of 2 oz copper connected to each lead - verified per Vishay's thermal derating curves (Fig. 2 and Fig. 5).
