Product details
Overview
P6KE150AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in power rails and signal lines. It features a 150V nominal standoff voltage (VWM = 121 V), 150V breakdown voltage range (135–165 V at 1 mA), clamps to ≤207 V at 3.0 A peak surge current, and uses DO-204AC (DO-15) package with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE150AH datasheet, P6KE150AH pinout, P6KE150AH application, or P6KE150AH equivalent, key selection criteria include its 121 V working voltage, 207 V max clamping voltage at 3.0 A, <1 μA leakage above 128 V, 175°C junction rating, and AEC-Q101 qualification - critical for automotive ECU, infotainment, and body electronics surge immunity design.
Technical Context
The P6KE150AH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 135–165 V breakdown range (tested at 1 mA). Its low dynamic impedance ensures rapid clamping response (<1.0 ps from 0 V to VBR), limiting transient energy delivered to downstream circuitry during 10/1000 µs surges.
Thermal performance is defined by a 175°C maximum junction temperature and derating curve per Fig.2; steady-state power dissipation is 5 W at 75°C with 9.5 mm lead length on 5×5 mm copper pads. Polarity is marked by cathode band, and device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards.
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 |
|---|---|---|---|
| SMBJ150A | DO-214AA package (smaller footprint), 150 V VBR min/max = 135–158 V, VC = 243 V @ 2.5 A | Higher clamping voltage (+36 V) and lower surge current rating reduce margin in high-energy automotive load dump scenarios | Select SMBJ150A only if board space is constrained and clamping margin allows ≥243 V at protected node |
| 1.5KE150A | Same DO-204AC package, higher 1500 W PPK rating, VBR = 135–158 V, VC = 220 V @ 6.8 A | Higher surge capacity suits heavy-duty industrial motor drives but increases cost and parasitic inductance vs. P6KE150AH | Choose 1.5KE150A where multi-pulse or repeated surge exposure exceeds 600 W limits |
Compared with SMBJ150A and 1.5KE150A, the P6KE150AH delivers optimal balance of AEC-Q101 compliance, 600 W surge capability in DO-15, and 207 V clamping - making it preferred for cost-sensitive, space-tolerant automotive and industrial power rail protection where single-event robustness is prioritized.

FAQ
What is the clamping voltage of the P6KE150AH and how is it measured?
The P6KE150AH has a maximum clamping voltage (VC) of 207 V at 3.0 A peak pulse current (IPP), tested using the standard 10/1000 µs double-exponential surge waveform. This value represents the upper limit of voltage seen by downstream components during a transient event and is guaranteed across the full operating temperature range per the manufacturer's test conditions.
Is the P6KE150AH suitable for bidirectional transient protection?
No - the P6KE150AH is a unidirectional TVS diode, indicated by the "H" suffix (not "CA" or "C") and confirmed by its single cathode band marking. For bidirectional protection, select P6KE150A or P6KE150CA variants, which provide symmetrical clamping in both polarities and lack polarity marking.
Does the P6KE150AH meet automotive qualification standards?
Yes - the "H" suffix explicitly denotes AEC-Q101 qualification per the manufacturer's ordering information. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), validating suitability for automotive powertrain, body, and infotainment systems.
What is the maximum junction temperature rating for the P6KE150AH?
The P6KE150AH has a maximum junction temperature (TJ) rating of +175°C, enabling reliable operation in under-hood environments and high-power industrial enclosures. Derating of peak pulse power begins above 25°C ambient per Figure 2 in the datasheet, with full 600 W capability maintained up to ~50°C ambient depending on PCB layout.
How does the P6KE150AH compare to the P6KE150A variant?
The P6KE150AH adds AEC-Q101 qualification and uses tighter VBR tolerance (143–158 V vs. 135–165 V for P6KE150A), resulting in more consistent clamping behavior. Both share identical DO-204AC packaging, 121 V VWM, and 207 V VC rating, but only P6KE150AH is approved for automotive use per TSC documentation.
