Product details
Overview
P6KE22CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 20.9–23.1 V breakdown voltage at 1 mA, 18.8 V stand-off voltage, 30.6 V maximum clamping voltage at 19.6 A peak pulse current, and operates from –55 °C to +175 °C - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P6KE22CA-E3/54 datasheet, P6KE22CA-E3/54 pinout, P6KE22CA-E3/54 application, or P6KE22CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B for telecom and automotive transient protection.
Technical Context
This device functions as a voltage-clamped shunt protector: under normal operation it presents high impedance (>1 MΩ at 18.8 V), but switches to low-impedance conduction within <1 ns when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM).
The bidirectional architecture enables symmetric clamping in AC-coupled or floating circuits without polarity constraints. It sustains repetitive 10/1000 μs surges at 0.01% duty cycle and meets JESD 22-B106 solderability (275 °C, 10 s) and JESD 201 Class 1A whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1 mA - defines reliable turn-on threshold for transient detection |
| VWM | 18.8 V - maximum continuous working voltage before leakage rises above 1 μA |
| VC @ IPPM | 30.6 V at 19.6 A - clamped voltage during 600 W surge, limiting downstream stress |
| PPPM | 600 W (10/1000 μs waveform) - peak surge energy handling capacity per transient |
| TJ max. | +175 °C - enables use in under-hood automotive and high-ambient industrial environments |
| RθJL | 20 °C/W - low junction-to-lead thermal resistance supports sustained surge dissipation |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional types; case diameter 3.3–3.5 mm, length ≥25.4 mm, lead length 6.15–6.55 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | No defined anode/cathode - terminals interchangeable; clamps voltage excursions in either polarity |
| Lead 1 / Lead 2 | Current path to PCB trace or heatsink | Both leads serve as low-inductance conduction paths; thermal performance depends on copper area and lead soldering |
Key Features
| Feature | Design Value |
|---|---|

| 600 W peak pulse power (10/1000 μs) | Withstands IEC 61000-4-5 Level 4 surges (4 kV line-earth, 2 kV line-line) without degradation |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| UL 497B recognized (QVGQ2) | Approved for telecom and industrial signal line protection per safety standard requirements |
| Low clamping ratio (VC/VBR ≈ 1.32) | Minimizes overvoltage exposure to protected ICs such as CAN transceivers or ADC front-ends |
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 |
|---|---|---|---|
| SMBJ22CA | DO-214AA package; lower RθJA (50 °C/W vs. 75 °C/W); same VBR, VC, PPPM | Better suited for surface-mount layouts with limited board space; requires rework of footprint and stencil | Select SMBJ22CA when automated SMT assembly and higher power density are prioritized over through-hole robustness. |
| 1.5KE22CA | Higher PPPM (1500 W); larger DO-201AD package; identical VBR/VC specs and bidirectional function | Used where legacy designs require higher surge margin or existing heatsinking accommodates larger body | Choose 1.5KE22CA when system-level surge testing exceeds 600 W or mechanical retention demands larger leadframe mass. |
Compared with SMBJ22CA and 1.5KE22CA, the P6KE22CA-E3/54 offers optimal balance of through-hole mechanical reliability, AEC-Q101 qualification, and cost-effective 600 W protection in compact DO-15 - ideal for automotive and industrial through-hole assemblies where layout flexibility and qualification traceability are critical.

FAQ
What is the clamping voltage of the P6KE22CA-E3/54 under maximum surge conditions?
The P6KE22CA-E3/54 exhibits a maximum clamping voltage (VC) of 30.6 V when subjected to its rated peak pulse current of 19.6 A (10/1000 μs waveform). This value is measured per JEDEC standards and guarantees that downstream circuitry remains below this voltage threshold during transient events, making the P6KE22CA-E3/54 suitable for protecting 24 V-rated interfaces and 3.3 V/5 V logic with appropriate series impedance.
Is the P6KE22CA-E3/54 suitable for automotive applications?
Yes, the P6KE22CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its operating junction temperature range of –55 °C to +175 °C, glass-passivated junction stability, and validation across temperature cycling, HTRB, and surge endurance make the P6KE22CA-E3/54 appropriate for engine control units, body electronics, and ADAS sensor interfaces.
How does the bidirectional design of the P6KE22CA-E3/54 affect circuit implementation?
The bidirectional architecture of the P6KE22CA-E3/54 eliminates polarity concerns during placement - both leads are functionally identical, enabling use in AC-coupled, floating, or differential signal paths without orientation checks. This simplifies assembly and supports symmetrical clamping in telecom lines, RS-485 buses, or sensor bridges where voltage reversals occur, unlike unidirectional variants such as P6KE22A.
What is the thermal resistance profile of the P6KE22CA-E3/54, and how does it impact layout?
The P6KE22CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. Effective heat dissipation relies on adequate copper pour connected to both leads; increasing pad area by ≥25 mm² per lead reduces effective RθJA by ~15 °C/W. This thermal behavior directly influences sustained surge capability in the P6KE22CA-E3/54 during repetitive transient events.
Does the P6KE22CA-E3/54 meet UL safety certification requirements?
Yes, the P6KE22CA-E3/54 carries Underwriters Laboratories recognition under UL 497B (file E136766) for both unidirectional and bidirectional protectors. This certification confirms compliance for use in telecom, industrial, and consumer equipment where safety-agency approval is mandatory - a verified requirement explicitly stated in the Vishay documentation for the P6KE22CA-E3/54.
