Product details
Overview
P4KE100CA-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 or power lines. It features a 100 V breakdown voltage (VBR min/max = 95.0–105 V), 85.5 V stand-off voltage (VWM), and clamps to ≤137 V at 2.9 A peak pulse current (IPPM) under 10/1000 μs waveform - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE100CA-E3/54 datasheet, P4KE100CA-E3/54 pinout, P4KE100CA-E3/54 application, or P4KE100CA-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, bidirectional clamping behavior, AEC-Q101 qualification status, and direct alternatives for ESD/transient protection design-in.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its 400 W peak pulse power rating (10/1000 μs) and low incremental surge resistance enable robust transient energy absorption without latch-up or thermal runaway.
It exhibits a temperature coefficient of breakdown voltage of +0.106 %/°C and maintains stable performance across –55 °C to +175 °C junction temperature range. The device is rated for 1.5 W steady-state power dissipation on infinite heatsink and supports 1000 μA maximum reverse leakage at VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 95.0 V / 105 V at 1.0 mA test current - defines reliable conduction onset window for bidirectional clamping |
| VWM | 85.5 V - maximum continuous working voltage before significant leakage; sets safe operating margin below VBR |
| VC @ IPPM | ≤137 V at 2.9 A (10/1000 μs) - peak clamped voltage seen by protected circuit during surge event |
| PPPM | 400 W - peak transient power it can absorb without failure; critical for lightning/inductive-switching immunity |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +175 °C - enables operation in under-hood automotive and industrial environments without derating |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: DO-41 (DO-204AL), axial-leaded, molded epoxy body with matte tin-plated leads; RoHS-compliant (E3 suffix), UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; symmetrical with cathode in bidirectional mode | No polarity marking on P4KE100CA-E3/54 - terminals are functionally identical for transient clamping in either direction |
| Cathode (unmarked end) | Current exit point in forward bias; symmetrical with anode in bidirectional mode | Identical terminal behavior to anode; bidirectional operation eliminates need for orientation-dependent PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable avalanche characteristics and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out with low-inductance traces |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, ADAS sensor interfaces, and body electronics |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage exposure to downstream ICs - critical for protecting 100 V-rated MOSFETs or CAN transceivers |
| DO-41 package with JESD 22-B106 solderability | Compatible with standard wave and reflow processes; 275 °C/10 s max solder dip tolerance simplifies manufacturing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | DO-214AA package; 100 W lower peak pulse power (300 W); 10% tighter VBR tolerance (90–110 V) | Better suited for space-constrained PCBs but requires higher layout precision to manage thermal dissipation | Select SMBJ100CA when board area is limited and surge energy is ≤300 W; verify thermal relief pad design for 1.5 W steady-state. |
| 1.5KE100CA | Same DO-41 package; 1500 W peak pulse power; higher IPPM (12.3 A); 10% higher VC (150 V) | Targets higher-energy threats like direct lightning injection; less precise clamping for sensitive 100 V rail protection | Choose 1.5KE100CA only when system-level testing confirms >400 W threat levels; avoid where strict <137 V clamping is required. |
Compared with P4KE100CA-E3/54, SMBJ100CA trades pulse power for compactness, while 1.5KE100CA increases surge capacity at the cost of clamping precision - making P4KE100CA-E3/54 the optimal balance for AEC-Q101-compliant 100 V line protection with tight VC control.

FAQ
What is the clamping voltage of P4KE100CA-E3/54 at its rated peak pulse current?
The P4KE100CA-E3/54 clamps to a maximum of 137 V when subjected to its specified peak pulse current of 2.9 A under the standard 10/1000 μs waveform. This value is measured across the device terminals during transient conduction and represents the upper voltage limit imposed on the protected circuit during surge events. The clamping voltage directly determines the stress level on downstream components such as microcontrollers or interface ICs.
Is P4KE100CA-E3/54 suitable for automotive applications?
Yes, P4KE100CA-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its –55 °C to +175 °C operating junction temperature range, glass-passivated junction, and validated surge endurance meet stringent automotive reliability requirements. The E3 suffix also ensures RoHS compliance and JESD 201 class 1A whisker resistance.
How does the bidirectional configuration of P4KE100CA-E3/54 affect PCB layout?
The bidirectional nature of P4KE100CA-E3/54 eliminates polarity sensitivity - both terminals are functionally identical, so no cathode band marking is present and orientation during placement has no electrical impact. This simplifies PCB assembly, reduces risk of misorientation defects, and allows symmetric routing on differential lines or unidirectional rails where reverse-voltage transients may occur.
What is the maximum steady-state power dissipation for P4KE100CA-E3/54?
P4KE100CA-E3/54 has a maximum steady-state power dissipation (PD) of 1.5 W when mounted on an infinite heatsink at lead temperature (TL) of 75 °C. This rating assumes ideal thermal conditions; actual usable power must be derated per Figure 5 in the datasheet based on ambient temperature and PCB copper area. It is not intended for continuous power regulation but for handling infrequent surge energy.
Does P4KE100CA-E3/54 have a specified junction capacitance?
No, the official Vishay datasheet for P4KE100CA-E3/54 does not specify junction capacitance (CJ). While typical CJ for DO-41 TVS diodes in this voltage range falls between 50–150 pF at zero bias, this value is not guaranteed or characterized for P4KE100CA-E3/54. For high-speed signal line protection where capacitance matters (e.g., USB, Ethernet), a capacitance-specified alternative such as SMAJ100CA should be evaluated.
