Product details
Overview
P4KE22C-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 22 V breakdown voltage (VBR min/max = 20.9–23.1 V), 400 W peak pulse power (10/1000 μs), and clamps to ≤30.6 V at 13.1 A peak pulse current - used in automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE22C-E3/54 datasheet, P4KE22C-E3/54 pinout, P4KE22C-E3/54 application, or P4KE22C-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, 175 °C max junction temperature, low incremental surge resistance, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical avalanche behavior in both polarities. Its glass-passivated junction enables fast response (<1 ns), low leakage (<1 μA at 18.8 V), and stable breakdown over temperature (0.092 %/°C coefficient). The unmarked DO-41 body indicates bidirectional polarity - no cathode band required.
It sustains repetitive 10/1000 μs surges at 0.01 % duty cycle, derates linearly above 25 °C ambient, and delivers 13.1 A peak pulse current before clamping to 30.6 V. Thermal resistance is 66 °C/W junction-to-lead, supporting reliable operation under transient stress without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V at 1.0 mA - defines precise avalanche onset window for predictable clamping threshold |
| VWM | 18.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPPM | 30.6 V at 13.1 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, enabling robust ESD/lightning surge immunity |
| TJ max | +175 °C - high-temperature operation supports under-hood automotive and industrial environments |
| RθJL | 66 °C/W - low thermal resistance allows efficient heat transfer to PCB leads during surge events |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package

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 | Same VBR range (20.9–23.1 V), but SMC (DO-214AB) package - 1.6× larger footprint, higher IPPM (23.9 A), lower RθJA | Preferred where board space permits and higher surge margin is needed; not drop-in due to different pad layout | Select SMBJ22CA when >20 A peak pulse current headroom or improved thermal dissipation is required. |
| 1.5KE22CA | Same DO-41 package and VBR, but 1500 W rating (vs. 400 W); larger chip, higher capacitance (~150 pF vs. ~50 pF) | Better for high-energy surges but unsuitable for high-speed data lines due to higher junction capacitance | Choose 1.5KE22CA only for low-frequency power rail protection where speed and capacitance are non-critical. |
Compared with SMBJ22CA and 1.5KE22CA, the P4KE22C-E3/54 offers optimal balance of compact DO-41 size, automotive qualification, and sufficient 400 W surge handling for signal-level protection - making it ideal for space-constrained, high-reliability sensor and interface designs.

FAQ
What does the "C" suffix indicate in P4KE22C-E3/54?
The "C" suffix in P4KE22C-E3/54 denotes bidirectional configuration - meaning the device clamps symmetrically for both positive and negative transients, with no polarity marking required. This differs from unidirectional variants (e.g., P4KE22A-E3/54) that feature a cathode band and conduct only in reverse bias. The P4KE22C-E3/54 is specifically intended for AC-coupled or floating signal lines where polarity cannot be guaranteed.
Is P4KE22C-E3/54 qualified for automotive applications?
Yes, P4KE22C-E3/54 is AEC-Q101 qualified - verified per stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress test (uHAST). This qualification confirms suitability for under-hood and cabin electronics where reliability under thermal and electrical stress is critical. The "HE3" variant (P4KE22CHE3/54) explicitly denotes AEC-Q101 compliance, but the E3/54 version shares identical die and qualification status per Vishay documentation.
What is the maximum clamping voltage of P4KE22C-E3/54 during a surge event?
The maximum clamping voltage (VC) of P4KE22C-E3/54 is 30.6 V at 13.1 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value represents the upper limit of voltage imposed on protected circuitry during a 400 W transient event. It ensures downstream components rated for ≤3.3 V or 5 V logic interfaces remain within safe operating limits when paired with appropriate series impedance.
Can P4KE22C-E3/54 replace P4KE22A-E3/54 in a design?
No - P4KE22C-E3/54 and P4KE22A-E3/54 are not interchangeable without circuit review. The "C" variant is bidirectional with symmetrical clamping, while the "A" variant is unidirectional and requires correct cathode orientation. Substituting one for the other may result in improper clamping or forward conduction during normal operation. Layout, grounding, and signal polarity must be re-evaluated if changing between these types.
What is the junction-to-lead thermal resistance (RθJL) of P4KE22C-E3/54?
The junction-to-lead thermal resistance (RθJL) of P4KE22C-E3/54 is 66 °C/W, as specified in Vishay's thermal characteristics table. This parameter quantifies how effectively heat generated during transient events transfers from the silicon junction to the device leads - critical for estimating temperature rise during repetitive surges. It assumes standard lead length (10 mm) and direct conduction to PCB copper, and supports reliable operation up to 175 °C junction temperature.
