Product details
Overview
P4KE400CA-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 400 W peak pulse power (10/1000 μs), 342 V standoff voltage (VWM), 380–420 V breakdown voltage (VBR), and clamps to ≤548 V at 0.73 A peak pulse current. Used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE400CA-E3/54 datasheet, P4KE400CA-E3/54 pinout, P4KE400CA-E3/54 application, or P4KE400CA-E3/54 equivalent, this page delivers verified electrical specs, DO-41 terminal mapping, bidirectional clamping behavior, AEC-Q101 qualification status, and real-world design context for transient protection in harsh environments.
Technical Context
The P4KE400CA-E3/54 operates as a symmetrical avalanche diode with identical forward and reverse breakdown characteristics due to its bidirectional CA construction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
It complies with AEC-Q101 for automotive use and is rated for -55 °C to +175 °C junction temperature. The device sustains 400 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, with thermal resistance RθJL = 66 °C/W and RθJA = 100 °C/W (lead length = 10 mm).

Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed between signal line and ground, absorbing transients before they reach sensitive IC inputs. Use Value: Maintains signal integrity by limiting voltage to ≤548 V during 400 W surges, preventing latch-up or gate oxide damage in downstream ASICs. |
Use Scenario: Safeguarding PLC digital input modules against inductive kickback from solenoids and relay coils. IC Role / Device Role / Timing Role: Standoff-mode TVS connected across input terminals, conducting only during overvoltage events. Use Value: Enables reliable operation in factory environments where 100 V/μs transients occur; 342 V VWM avoids false triggering during normal 24 V DC operation. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Surge protection on Ethernet PHY side of PoE-powered devices exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary front-end clamp on data pair, coordinated with common-mode chokes and secondary TVS. Use Value: Withstands repetitive 10/1000 μs surges up to 400 W, meeting GR-1089-CORE Level 3 telecom surge requirements. |
Use Scenario: Secondary-side transient suppression on AC-DC adapter output rails feeding USB-C PD controllers. IC Role / Device Role / Timing Role: Low-leakage (1.0 μA) bidirectional clamp ensuring no standby current drain while guarding against output overvoltage faults. Use Value: Prevents damage to downstream USB PD ICs during output short-circuit recovery or regulator failure, with clamping below 548 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ400CA | DO-214AA package; 600 W PPPM; lower clamping voltage (VC = 533 V @ 0.75 A); higher capacitance (~100 pF) | Better suited for space-constrained PCBs requiring higher power rating; less ideal for high-frequency signal lines due to higher CJ | Select SMBJ400CA when board layout allows SMC footprint and higher surge margin is required beyond 400 W |
| 1.5KE400CA | DO-201AD package; 1500 W PPPM; same VWM/VBR range; larger thermal mass but longer lead inductance | Preferred for high-energy industrial motor drives; not recommended for fast-edge digital signals due to slower effective response | Choose 1.5KE400CA only when system-level surge tests exceed IEC 61000-4-5 Level 4 and thermal dissipation dominates layout constraints |
Compared with SMBJ400CA and 1.5KE400CA, the P4KE400CA-E3/54 offers optimal balance of compact DO-41 form factor, AEC-Q101 qualification, and precise 342 V standoff-making it the preferred choice for automotive and industrial designs where reliability, size, and standardized qualification are jointly prioritized.

FAQ
What is the standoff voltage (VWM) of the P4KE400CA-E3/54?
The P4KE400CA-E3/54 has a maximum standoff voltage (VWM) of 342 V, meaning it remains non-conductive up to this DC or RMS voltage level under normal operating conditions. This value ensures compatibility with 277 V AC mains-derived DC rails and 300 V nominal industrial bus systems while avoiding false triggering during routine operation.
Is the P4KE400CA-E3/54 qualified for automotive applications?
Yes, the P4KE400CA-E3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and ESD per JESD22-A114. This qualification confirms its suitability for under-hood and cabin-mounted automotive electronics such as body control modules and sensor signal conditioning circuits.
What does the "CA" suffix indicate in P4KE400CA-E3/54?
The "CA" suffix denotes that the P4KE400CA-E3/54 is a bidirectional Transient Voltage Suppressor, with symmetrical breakdown characteristics in both forward and reverse directions. Unlike unidirectional variants (e.g., P4KE400A), it requires no polarity orientation during placement and clamps transients regardless of voltage polarity.
What is the clamping voltage (VC) of the P4KE400CA-E3/54 at rated peak pulse current?
The P4KE400CA-E3/54 clamps to a maximum of 548 V when subjected to its rated peak pulse current of 0.73 A under the standard 10/1000 μs waveform. This VC value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream ICs remain within absolute maximum ratings.
Does the P4KE400CA-E3/54 have RoHS compliance and lead-free plating?
Yes, the P4KE400CA-E3/54 carries the "E3" suffix, indicating full RoHS compliance and matte tin-plated leads that meet J-STD-002 solderability standards and JESD 201 Class 1A whisker resistance requirements-ensuring reliable interconnect performance in thermally cycled and high-reliability applications.
