Product details
Overview
P4KE150CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features a 150 V breakdown voltage (VBR min/max = 143 V / 158 V), 128 V standoff voltage (VWM), 207 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P4KE150CAHE3/54 datasheet, P4KE150CAHE3/54 pinout, P4KE150CAHE3/54 application, or P4KE150CAHE3/54 equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial power rails, and telecom line conditioning where bidirectional surge immunity and low clamping voltage (VC = 207 V at IPPM) are critical.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), while the DO-41 package supports manual or automated through-hole assembly.
The device delivers 400 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance RθJL = 66 °C/W and RθJA = 100 °C/W, allowing reliable operation up to TJ = +175 °C. Its clamping voltage of 207 V at 207 A provides predictable overvoltage limiting during ESD or lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V at 1.0 mA test current - defines precise voltage threshold where clamping begins |
| VWM | 128 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 207 V at 207 A - clamped voltage during full 400 W transient, directly limiting downstream IC stress |
| PPPM | 400 W - peak surge power handling capability per 10/1000 µs waveform, duty cycle ≤ 0.01 % |
| IPPM | 207 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 |

| Telecom Line Conditioning | Consumer Power Adapter Input Protection |
|
Use Scenario: Shielding Ethernet PHY front-ends and RS-485 transceivers from lightning-induced surges on outdoor or building-entry cabling. IC Role / Device Role / Timing Role: Primary-level bidirectional surge suppressor mounted at connector interface before isolation or signal conditioning stages. Use Value: Symmetrical clamping ensures equal protection on both line conductors, meeting IEC 61000-4-5 4 kV (line-earth) requirements with margin. |
Use Scenario: Adding secondary-side overvoltage protection on 12–19 V DC outputs of laptop adapters and USB-C PD power supplies. IC Role / Device Role / Timing Role: Fast-reacting clamp preventing output overvoltage faults from damaging connected devices during regulator failure. Use Value: 207 V clamping voltage provides >50 V headroom above 150 V worst-case fault conditions, avoiding false triggering during normal ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Surface-mount SMB package (vs. through-hole DO-41); same VBR, VC, and PPPM; lower IPPM (134 A) | Preferred for space-constrained PCBs and automated SMT assembly; not suitable for high-vibration mechanical mounting | Select SMBJ150CA when board real estate or reflow compatibility outweighs lead strength and manual repairability needs. |
| 1.5KE150CA | Higher PPPM (1500 W) and IPPM (61.9 A); larger DO-201AE package; same VBR/VC specs | Better suited for higher-energy threats (e.g., direct lightning coupling), but requires larger footprint and higher cost | Choose 1.5KE150CA only if system-level testing confirms >400 W surge energy exposure; otherwise P4KE150CAHE3/54 offers optimal cost/performance balance. |
Compared with SMBJ150CA and 1.5KE150CA, P4KE150CAHE3/54 delivers AEC-Q101-qualified bidirectional clamping in a compact, serviceable through-hole package - making it ideal for automotive and industrial designs requiring proven reliability, field repairability, and moderate surge immunity without over-engineering.

This tight ±5 % tolerance ensures predictable clamping onset and consistent protection behavior across production lots and temperature ranges from –55 °C to +175 °C.
Is P4KE150CAHE3/54 suitable for automotive applications?
Yes, P4KE150CAHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction - including glass-passivated junction, DO-41 package with matte tin leads, and 175 °C max junction temperature - meets requirements for engine control units, body electronics, and ADAS sensor modules exposed to thermal cycling, humidity, and repetitive surge events.
How does the bidirectional design of P4KE150CAHE3/54 affect its circuit placement?
The bidirectional nature of P4KE150CAHE3/54 means it functions identically in both polarities, with no anode/cathode distinction required in layout. It can be placed across AC-coupled lines, floating differential pairs, or ungrounded power rails without orientation constraints - simplifying schematic capture and PCB routing compared to unidirectional TVS diodes.
What is the clamping voltage of P4KE150CAHE3/54 under surge conditions?
P4KE150CAHE3/54 clamps to a maximum of 207 V when subjected to its rated 207 A peak pulse current (10/1000 µs waveform). This VC value is measured under standardized conditions and represents the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream components remain within safe operating area.
Does P4KE150CAHE3/54 have RoHS and lead-free compliance?
Yes, P4KE150CAHE3/54 carries the HE3 suffix, indicating full RoHS compliance and AEC-Q101 qualification.
