Product details
Overview
P4KE22CA-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 22 V breakdown voltage (VBR min/max = 20.9–23.1 V), 18.8 V standoff voltage (VWM), 30.6 V maximum clamping voltage at 13.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE22CA-E3/54 datasheet, P4KE22CA-E3/54 pinout, P4KE22CA-E3/54 application, or P4KE22CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification for automotive use, DO-41 mechanical compatibility, low leakage (<1.0 μA at VWM), and thermal resistance of 100 °C/W (junction-to-ambient).
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging a glass-passivated PN junction to respond within picoseconds to ESD and surge events. Its bidirectional symmetry ensures identical electrical characteristics in forward and reverse conduction, with no polarity marking required on the DO-41 body.
It delivers 400 W peak pulse power handling under standardized 10/1000 μs waveform conditions at 0.01 % duty cycle, with clamping performance validated at 13.1 A IPPM. Thermal derating follows a defined curve down to zero power at 175 °C junction temperature, supported by RθJA = 100 °C/W and RθJL = 66 °C/W.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in vehicle body control modules from load dump and jump-start transients. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across input rail upstream of DC/DC converter. Use Value: Limits rail voltage to ≤30.6 V during 100 V/50 ms load dump, preventing damage to 36 V-rated regulators and MCU power supplies. |
Use Scenario: Safeguarding analog outputs of pressure or temperature sensors connected to PLC I/O modules. IC Role / Device Role / Timing Role: Low-leakage TVS shunting induced surges on 4–20 mA current loop wiring. Use Value: Sub-1 μA leakage avoids calibration drift; fast response preserves signal integrity during nearby relay switching. |
| Telecom Line Surge Protection | Consumer USB Port ESD Protection |
Use Scenario: Shielding RS-485 transceivers in base station backhaul equipment from lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamping device on differential bus lines referenced to local ground. Use Value: Symmetric clamping ensures equal protection for both A and B lines without polarity concerns. |
Use Scenario: Adding secondary-level ESD robustness to USB 2.0 data lines in smart home hubs. IC Role / Device Role / Timing Role: Standoff voltage (18.8 V) exceeds USB VBUS swing, enabling safe placement near connector. Use Value: 30.6 V clamping prevents latch-up in USB PHY ICs rated for 3.3 V I/O with 36 V absolute max. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | DO-214AA package; 600 W PPPM; lower RθJA (50 °C/W); same VBR range | Better thermal performance in high-density PCB layouts; higher surge margin for repeated events | Select SMBJ22CA when board space allows SMC/SMB footprint and higher pulse energy handling is required. |
| 1.5KE22CA | DO-201AD package; 1500 W PPPM; larger body; higher IPPM (65.2 A) | Designed for primary-level AC/DC input protection; not optimized for signal-line placement | Choose 1.5KE22CA only for high-energy front-end protection where PCB real estate and cost allow larger through-hole devices. |
Compared with SMBJ22CA and 1.5KE22CA, P4KE22CA-E3/54 offers optimal balance of compact DO-41 form factor, AEC-Q101 qualification, and 400 W surge capability-making it ideal for space-constrained automotive and industrial signal-line protection where moderate energy levels dominate.

FAQ
What does the "CA" suffix indicate in P4KE22CA-E3/54?
The "CA" suffix in P4KE22CA-E3/54 denotes a bidirectional configuration, meaning the device provides symmetrical transient voltage suppression in both polarities. Unlike unidirectional variants (e.g., P4KE22A), it has no cathode marking and functions identically whether positive or negative surge voltage is applied across its terminals.
Is P4KE22CA-E3/54 qualified for automotive applications?
Yes, P4KE22CA-E3/54 is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 16-Sep-2021. This qualification validates its reliability under automotive temperature cycling, humidity, mechanical shock, and surge stress conditions-making it suitable for engine control units, body electronics, and ADAS sensor modules.
What is the maximum clamping voltage of P4KE22CA-E3/54 and at what current?
The maximum clamping voltage (VC) of P4KE22CA-E3/54 is 30.6 V, measured at its peak pulse current (IPPM) of 13.1 A under the standard 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events.
Can P4KE22CA-E3/54 be used in place of a unidirectional TVS like P4KE22A?
No-P4KE22CA-E3/54 is strictly bidirectional and lacks polarity marking, whereas P4KE22A is unidirectional with a cathode band. Substituting one for the other risks incorrect orientation and failure to suppress reverse-polarity transients. Circuit layout and schematic symbol must match the device's polarity architecture.
What packaging format is supplied for P4KE22CA-E3/54?
P4KE22CA-E3/54 is supplied in 13-inch diameter paper tape and reel format, with a base quantity of 5500 units per reel (ordering code /54). The E3 suffix confirms RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker resistance requirements.
