Product details
Overview
P4KE22CAHE3/54 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 clamping voltage (VC) at 13.1 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and sensor signal lines in automotive ECUs.
For engineers reviewing the P4KE22CAHE3/54 datasheet, P4KE22CAHE3/54 pinout, P4KE22CAHE3/54 application, or P4KE22CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-41 mechanical compatibility, thermal resistance (RθJL = 66 °C/W), and low leakage (<1 µA at VWM).
Technical Context
This device operates as a voltage-clamping protection element in bidirectional configurations, responding to transient overvoltages in either polarity without polarity marking. Its glass-passivated junction enables fast response time and stable clamping performance under repetitive 10/1000 µs surges at 0.01% duty cycle.
Designed for automotive-grade reliability, the P4KE22CAHE3/54 meets AEC-Q101 stress testing requirements and supports operation from −55 °C to +175 °C junction temperature. Its 1.5 W steady-state power dissipation and 66 °C/W junction-to-lead thermal resistance support direct PCB mounting without heatsinking in moderate-power transient scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 18.8 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 30.6 V at 13.1 A - clamped voltage during 400 W transient, limiting downstream IC stress |
| PPPM | 400 W - peak surge energy absorption capacity with standard 10/1000 µs test waveform |
| IPPM | 13.1 A - maximum non-repetitive surge current the device safely conducts without failure |
| TJ max | +175 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures |
| RθJL | 66 °C/W - defines thermal path efficiency from junction to lead, critical for sustained surge handling |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional operation; compliant with J-STD-002 solderability and JESD 201 class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Bidirectional transient conduction path | Both terminals function identically - no cathode band; symmetric clamping in positive/negative voltage excursions |
| Lead 1 / Lead 2 | PCB interconnect interface | Leads serve as both electrical connection and primary thermal path (RθJL = 66 °C/W); 10 mm lead length assumed for thermal derating |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Glass passivated junction | Enables stable VBR tolerance (±5%), low leakage (<1 µA), and long-term reliability under humidity and bias |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) when properly routed and decoupled |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic interfaces |
| UL 94 V-0 molding compound | Ensures flame-retardant enclosure integrity during fault conditions in enclosed systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22CA | DO-214AA package; higher IPPM (23.9 A), lower VC (35.5 V), same VWM/VBR range | Surface-mount footprint; better suited for high-density layouts where through-hole DO-41 is impractical | Select SMBJ22CA when board space is constrained and reflow assembly is used; verify thermal pad layout for 1.5 W dissipation. |
| 1.5KE22CA | Higher PPPM (1500 W); larger DO-201 package; identical VBR, VWM, VC specs | Used where higher single-event energy (e.g., ISO 7637-2 Pulse 5a) must be absorbed without cascading failure | Choose 1.5KE22CA for heavy-duty industrial power supply inputs or battery disconnect circuits requiring >1 kW surge margin. |
Compared with SMBJ22CA and 1.5KE22CA, the P4KE22CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-41 through-hole mechanical robustness, and 400 W surge handling - making it ideal for cost-sensitive, high-reliability automotive and industrial control boards where manual or wave-solder assembly is employed.

FAQ
What does the "CA" suffix indicate in P4KE22CAHE3/54?
The "CA" suffix denotes bidirectional configuration: the P4KE22CAHE3/54 conducts and clamps transient overvoltages equally in both polarities, with no cathode marking on the DO-41 body. This distinguishes it from unidirectional variants (e.g., P4KE22A) that feature a cathode band and conduct only in reverse bias. The CA version is selected when protection is needed against AC-coupled transients or undefined polarity surges.
Is P4KE22CAHE3/54 suitable for protecting 3.3 V logic circuits?
No - the P4KE22CAHE3/54 is not appropriate for direct protection of 3.3 V logic. Its 18.8 V standoff voltage (VWM) and 30.6 V clamping voltage (VC) far exceed safe operating limits for 3.3 V interfaces. It is intended for higher-voltage domains such as 12 V automotive buses, 24 V industrial I/O, or 48 V telecom lines. For 3.3 V logic, use low-VWM TVS devices like SMAJ3.3A or SOD323-packaged variants.
How does the HE3 suffix differ from E3 in P4KE22CAHE3/54?
The HE3 suffix indicates AEC-Q101 qualification and JESD 201 class 2 whisker resistance, whereas E3 denotes commercial-grade RoHS compliance only. P4KE22CAHE3/54 is fully qualified for automotive applications including under-hood environments, while P4KE22CAE3/54 is restricted to commercial/industrial use. Both share identical electrical specs and DO-41 packaging, but HE3 undergoes extended stress testing per automotive standards.
Can P4KE22CAHE3/54 be used in parallel to increase surge current handling?
No - paralleling P4KE22CAHE3/54 devices is not recommended due to mismatched VBR tolerances (±5%) causing uneven current sharing and potential thermal runaway. For higher IPPM, select a single higher-rated device such as 1.5KE22CA (1500 W) or SMBJ22CA (600 W). If system-level redundancy is required, implement separate protected branches rather than device paralleling.
What is the maximum allowable lead temperature during soldering for P4KE22CAHE3/54?
The maximum solder dip temperature for P4KE22CAHE3/54 is 275 °C for up to 10 seconds, per JESD 22-B106. Wave soldering profiles must stay within this limit to avoid internal delamination or junction degradation. Reflow profiles are not applicable since the DO-41 package is through-hole; for surface-mount alternatives, refer to SMBJ22CA or SMCJ22CA specifications.
