Product details
Overview
P4KE27CA-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 27 V breakdown voltage (VBR min/max = 25.7–28.4 V at 1.0 mA), 23.1 V standoff voltage (VWM), 37.5 V clamping voltage (VC) at 10.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and automotive ECUs against inductive switching surges.
For engineers reviewing the P4KE27CA-E3/54 datasheet, P4KE27CA-E3/54 pinout, P4KE27CA-E3/54 application, or P4KE27CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 leaded package compatibility with through-hole PCB layouts, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and low leakage (<1.0 μA at VWM) for low-power sensor line protection.
Technical Context
The P4KE27CA-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its 10/1000 μs surge response enables suppression of fast transients from relay coil de-energization or load dump events without forward conduction during normal operation.
It exhibits a temperature coefficient of +0.096 %/°C for VBR, ensuring predictable voltage drift over -55 °C to +175 °C operating range. With RθJA = 100 °C/W and RθJL = 66 °C/W, thermal performance supports reliable operation under repetitive surge conditions when mounted on standard copper land patterns.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | DO-214AA package, 24 V VWM, 38.9 V VC @ 10.3 A, 600 W PPPM | Surface-mount alternative with higher power rating but larger footprint and different thermal profile | Select when board space allows SMT placement and higher surge margin is required |
| 1.5KE27CA | DO-201AE package, same VBR/VWM/VC, 1500 W PPPM, higher IPPM (43.5 A) | Through-hole alternative with greater surge capacity but longer lead inductance affecting high-frequency clamping | Select when legacy DO-201AE socket compatibility or >400 W surge immunity is mandatory |
Compared with SMBJ24CA and 1.5KE27CA, the P4KE27CA-E3/54 offers optimal balance of DO-41 through-hole manufacturability, AEC-Q101 qualification, and 400 W surge handling - making it preferred for cost-sensitive automotive and industrial designs where leaded assembly and proven field reliability are prioritized.

FAQ
What is the clamping voltage of the P4KE27CA-E3/54 under a 10/1000 μs surge?
The P4KE27CA-E3/54 clamps to a maximum of 37.5 V when subjected to its rated 10.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures downstream ICs remain within safe voltage limits during transient events.
Is the P4KE27CA-E3/54 suitable for automotive applications?
Yes, the P4KE27CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its -55 °C to +175 °C operating junction temperature range, DO-41 mechanical robustness, and compliance with ISO 7637-2 surge test profiles make it appropriate for engine control units, body electronics, and infotainment power rail protection.
Does the P4KE27CA-E3/54 have polarity markings on the package?
No, the P4KE27CA-E3/54 is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction means either lead may connect to either side of the protected circuit - simplifying layout and eliminating orientation errors during manual or automated assembly.
What is the maximum leakage current of the P4KE27CA-E3/54 at its standoff voltage?
At its maximum working voltage of 23.1 V (VWM), the P4KE27CA-E3/54 exhibits a maximum reverse leakage current of 1.0 μA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor circuits and avoids loading effects in precision analog paths.
Can the P4KE27CA-E3/54 be used in place of unidirectional TVS diodes like P4KE27A-E3/54?
No - the P4KE27CA-E3/54 is strictly bidirectional and cannot replace unidirectional types such as P4KE27A-E3/54 in DC-biased circuits where forward conduction must be blocked in one direction. Substitution requires verifying circuit topology, bias conditions, and clamping symmetry requirements before implementation.
