Product details
Overview
P4KE30CHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features a 30 V breakdown voltage (VBR min/max = 28.5–31.5 V at 1.0 mA), 25.6 V stand-off voltage (VWM), 41.4 V maximum clamping voltage (VC) at 9.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE30CHE3/54 datasheet, P4KE30CHE3/54 pinout, P4KE30CHE3/54 application, or P4KE30CHE3/54 equivalent, this AEC-Q101 qualified, RoHS-compliant TVS diode supports automotive-grade surge protection design with verified bidirectional clamping behavior, low leakage (<1.0 μA at VWM), and stable thermal performance up to 175 °C junction temperature.
Technical Context
This device operates as a voltage-clamping protector in bidirectional configurations-no polarity marking required-and responds within picoseconds to transient overvoltages induced by inductive switching or ESD events. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping across repetitive 0.01% duty cycle pulses.
The P4KE30CHE3/54 delivers 41.4 V clamping at 9.7 A (10/1000 μs), with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient), supporting reliable operation under sustained surge stress when mounted on PCB traces with adequate copper area.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30CA | Surface-mount SMB package; same VBR range (28.5–31.5 V); 600 W PPPM; lower RθJA (50 °C/W) | Requires PCB re-layout; better suited for high-density automotive modules with automated assembly | Select SMBJ30CA when board space is constrained and SMT process is available. |
| 1.5KE30CA | Higher PPPM (1500 W); same DO-41 package; wider VBR tolerance (±10%); higher VC (48.4 V) | Used where higher energy transients occur (e.g., heavy industrial motor drives) | Choose 1.5KE30CA only if system-level testing confirms need for >400 W surge margin. |
Compared with SMBJ30CA and 1.5KE30CA, the P4KE30CHE3/54 offers optimal balance of AEC-Q101 qualification, proven DO-41 reliability, and precise 5% VBR tolerance-making it preferred for cost-sensitive, through-hole automotive and industrial designs requiring traceable qualification and legacy compatibility.

FAQ
What is the breakdown voltage range of the P4KE30CHE3/54?
The P4KE30CHE3/54 has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1.0 mA test current, measured in both directions due to its bidirectional construction. This tight ±5% tolerance ensures predictable clamping onset and supports precise circuit protection margins in automotive and industrial applications where voltage rails must remain within strict limits.
Is the P4KE30CHE3/54 suitable for automotive applications?
Yes, the P4KE30CHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its DO-41 package, 175 °C maximum junction temperature, and validation across temperature cycling, humidity, and surge stress make it appropriate for engine control units, body electronics, and ADAS sensor interfaces where reliability under thermal and electrical stress is mandatory.
How does the P4KE30CHE3/54 differ from unidirectional P4KE30A variants?
The P4KE30CHE3/54 is bidirectional with no polarity marking and symmetric clamping in both directions, whereas P4KE30A is unidirectional with a cathode band and conducts only in reverse bias. The P4KE30CHE3/54 replaces two unidirectional devices in AC-coupled or floating-line applications, simplifying layout and reducing BOM count in differential signal protection schemes.
What is the maximum clamping voltage of the P4KE30CHE3/54 during a 400 W transient?
At its rated 400 W peak pulse power (10/1000 μs waveform), the P4KE30CHE3/54 clamps to a maximum of 41.4 V when subjected to 9.7 A peak pulse current. This value is specified in the Vishay datasheet (Document Number 88365, page 2) and represents the worst-case voltage imposed on protected circuitry during standardized surge events.
Does the P4KE30CHE3/54 require heatsinking for standard operation?
No external heatsink is required for transient suppression duty cycles (e.g., 0.01% duty cycle per datasheet), but thermal design must account for RθJL = 66 °C/W and RθJA = 100 °C/W. For repeated surges or elevated ambient temperatures, increasing copper pad area on both leads significantly improves heat dissipation and maintains safe junction temperature below 175 °C.
