Product details
Overview
P4KE150C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a 150V nominal standoff voltage, 135–165V breakdown range at 1mA test current, 121V working voltage, ≤1μA reverse leakage at VWM, and clamps transients to 215V at 1.9A peak pulse current under 10/1000μs waveform - deployed in automotive lighting control modules and industrial PLC I/O protection.
For engineers reviewing the P4KE150C datasheet, P4KE150C pinout, P4KE150C application, or P4KE150C equivalent, key selection criteria include bidirectional clamping capability, DO-41 package compatibility, AEC-Q101 qualification status, thermal derating above 25°C, and compliance with IEC 61000-4-5 Level 4 surge immunity requirements.
Technical Context
The P4KE150C operates as a silicon avalanche diode with symmetrical bidirectional conduction, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its junction structure delivers sub-nanosecond response (<5ns) to fast transients and maintains low dynamic impedance during clamping.
Rated for 400W peak pulse power at 10/1000μs, it sustains 175°C maximum junction temperature and exhibits a +0.108%/°C temperature coefficient of VBR - critical for stable clamping across automotive under-hood thermal 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 |
|---|---|---|---|
| Littelfuse SMAJ150CA | Same DO-214AC (SMA) package; 150V bidirectional; 400W rating; slightly higher clamping voltage (243V @ 1.6A) | Surface-mount only; requires PCB rework vs. through-hole P4KE150C | Select when board space is constrained and reflow assembly is preferred |
| ON Semiconductor 1.5KE150CA | Higher 1500W rating; same 150V nominal; DO-201AE (DO-27) package; longer lead time | Over-specified for 400W use cases; larger footprint and higher cost | Select only if system-level surge testing exceeds IEC 61000-4-5 Level 4 |
Compared with SMAJ150CA and 1.5KE150CA, the P4KE150C offers optimal balance of proven reliability in through-hole designs, AEC-Q101 qualification path, and cost-effective DO-41 manufacturability - making it ideal for legacy industrial controls and automotive subsystems where leaded assembly remains standard.

FAQ
What is the polarity configuration of P4KE150C?
The P4KE150C is a bidirectional TVS diode with symmetrical avalanche characteristics - neither terminal is designated anode or cathode. It provides identical clamping behavior in both directions, making it suitable for AC signal lines, differential interfaces, and ungrounded power rails where polarity cannot be guaranteed. No cathode band marking is present on the DO-41 package.
Does P4KE150C meet AEC-Q101 qualification?
The base P4KE150C variant is not AEC-Q101 qualified; however, the P4KE150CH variant (with "H" suffix) is explicitly qualified per AEC-Q101 Rev D for automotive applications. Engineers requiring automotive-grade validation must specify P4KE150CH - the "C" suffix alone denotes bidirectional configuration but does not imply qualification.
What is the maximum clamping voltage of P4KE150C under surge conditions?
The P4KE150C clamps to a maximum of 215V when subjected to its rated 1.9A peak pulse current under the standard 10/1000μs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during full-rated surge events - critical for ensuring downstream components remain within absolute maximum ratings.
How does P4KE150C compare to unidirectional P4KE150A?
The P4KE150C is bidirectional with symmetrical VBR (135–165V) in both directions, while P4KE150A is unidirectional with cathode band marking and forward voltage drop (~3.5V). P4KE150C suits AC-coupled or floating nodes; P4KE150A is used for DC rail protection where polarity is fixed. Their clamping voltages differ: P4KE150A clamps at 207V, P4KE150C at 215V.
Can P4KE150C be used in parallel for higher surge current handling?
No - P4KE150C should not be paralleled due to mismatch in avalanche voltage thresholds, which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a single higher-rated device such as 1.5KE150CA (1500W), or implement staged protection with upstream current-limiting resistors and downstream low-capacitance TVS arrays.
