Product details
Overview
P6KE22A-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 20.9 V minimum breakdown voltage (VBR), 18.8 V maximum stand-off voltage (VWM), 30.6 V clamping voltage (VC) at 19.6 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed across automotive sensor signal lines, industrial I/O ports, and DC power rails.
For engineers reviewing the P6KE22A-E3/54 datasheet, P6KE22A-E3/54 pinout, P6KE22A-E3/54 application, or P6KE22A-E3/54 equivalent, this page delivers verified electrical parameters, thermal derating behavior, clamping performance under surge conditions, and AEC-Q101 qualification status for automotive-grade transient protection design.
Technical Context
The P6KE22A-E3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering bidirectional-capable protection architecture adapted for unidirectional polarity via cathode-band marking. Its 20.9–23.1 V breakdown range ensures precise overvoltage thresholding while maintaining low leakage (<1.0 μA at 18.8 V) and fast sub-nanosecond response time.
Thermal performance is defined by 20 °C/W junction-to-lead resistance and 75 °C/W junction-to-ambient resistance, enabling reliable operation up to 175 °C junction temperature. The device sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits +0.092 %/°C temperature coefficient of VBR, supporting stable clamping across wide ambient ranges.
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 |
|---|---|---|---|
| SMBJ22A | DO-214AA package, 22 V nominal VBR, same 600 W rating but lower IPPM (32.4 A) and higher VC (35.5 V) | Surface-mount alternative requiring PCB layout change; better suited for high-density consumer PCBs | Select SMBJ22A when space-constrained SMT assembly is required and higher clamping voltage is acceptable. |
| 1.5KE22A | Same DO-15 package, identical VBR/VC specs, but rated for 1500 W peak power and higher IFSM (200 A) | Higher-power industrial applications where surge margin beyond 600 W is mandated | Choose 1.5KE22A when protecting circuits subject to repeated high-energy transients such as AC motor drives or grid-tied inverters. |
Compared with SMBJ22A and 1.5KE22A, the P6KE22A-E3/54 offers optimal balance of cost, proven AEC-Q101 qualification, and axial-leaded ease of through-hole prototyping and service replacement - making it preferred for automotive Tier 2 suppliers and industrial OEMs prioritizing qualification traceability and mechanical robustness.

FAQ
What is the maximum clamping voltage of the P6KE22A-E3/54 under surge conditions?
The P6KE22A-E3/54 has a maximum clamping voltage (VC) of 30.6 V when subjected to its rated peak pulse current of 19.6 A using the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and ensures predictable voltage limiting during transient events, directly protecting downstream 3.3 V or 5 V logic interfaces from overvoltage stress. The P6KE22A-E3/54 maintains this clamping performance across its specified operating temperature range.
Is the P6KE22A-E3/54 suitable for automotive applications?
Yes, the P6KE22A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. Its DO-15 package, 175 °C maximum junction temperature, and robust surge handling (100 A IFSM, 600 W PPPM) meet stringent automotive environmental and reliability requirements. The E3 suffix denotes RoHS compliance and JESD 201 Class 1A whisker resistance, further validating the P6KE22A-E3/54 for under-hood deployment.
How does the P6KE22A-E3/54 differ from bidirectional TVS diodes like P6KE22CA?
The P6KE22A-E3/54 is unidirectional and features a cathode band for polarity identification, allowing it to conduct only in forward bias during surge events - ideal for DC line protection where reverse conduction must be blocked. In contrast, P6KE22CA is bidirectional with no polarity marking and clamps in both directions, suited for AC signal lines or differential buses. The P6KE22A-E3/54's VWM is 18.8 V versus 18.2 V for P6KE22CA, reflecting different standoff optimization for respective topologies.
What is the thermal resistance profile of the P6KE22A-E3/54?
The P6KE22A-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient resistance (RθJA) of 75 °C/W at TA = 25 °C. These values enable effective heat dissipation through PCB copper pours or direct lead soldering, supporting continuous power dissipation up to 5.0 W on an infinite heatsink at TL = 75 °C. Derating curves in the Vishay datasheet (Fig. 2 and Fig. 5) define safe operating limits for elevated ambient temperatures, critical for the P6KE22A-E3/54's use in enclosed industrial enclosures.
Can the P6KE22A-E3/54 be used in parallel for higher surge current handling?
No, the P6KE22A-E3/54 is not recommended for parallel operation due to inherent parameter variation (e.g., VBR tolerance ±5 %) that causes uneven current sharing and potential thermal runaway. For higher surge capacity, Vishay specifies discrete higher-power alternatives such as 1.5KE22A (1500 W) or stacked TVS arrays. System-level protection should instead use coordinated staging - e.g., gas discharge tube + P6KE22A-E3/54 - rather than paralleling identical P6KE22A-E3/54 units.
