Product details
Overview
P6KA10AHE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 9.5 V to 10.5 V breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 41.4 A, and operates up to +185 °C junction temperature - deployed in automotive engine control units to safeguard MOSFET gate drivers from load dump transients.
For engineers reviewing the P6KA10AHE3/54 datasheet, P6KA10AHE3/54 pinout, P6KA10AHE3/54 application, or P6KA10AHE3/54 equivalent, key selection criteria include unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, low clamping ratio (VC/VBR ≈ 1.45), and thermal stability under high-reliability automotive ambient conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for high-temperature reliability. Its 185 °C maximum junction temperature and AEC-Q101 qualification confirm suitability for under-hood automotive environments where sustained thermal stress and repetitive surge events occur.
The device delivers precise clamping performance with a 0.073 %/°C temperature coefficient of VBR, ensuring stable breakdown across wide operating ranges. Its 10 µA max reverse leakage at VWM (TJ = 150 °C) and 3.5 V max forward voltage at 50 A support low-power standby integrity and high-current surge handling without forward conduction interference.
Key Specifications

IC Role / Device Role / Timing Role: Acts as primary clamp on the negative rail, conducting bidirectionally via system grounding scheme with complementary positive-rail TVS. Use Value: Withstands 600 W peak pulse power and 75 A non-repetitive surge, meeting ITU-T K.20/21 immunity requirements. | Use Scenario: Front-end protection for universal-input AC/DC adapters handling 100–240 VAC, where rectified DC bus faces surge coupling from mains transients. IC Role / Device Role / Timing Role: Mounted across bulk capacitor terminals to clamp overvoltage spikes before they overstress electrolytic capacitors or PWM controllers. Use Value: 185 °C TJ rating allows placement near hot-switching MOSFETs without thermal runaway risk during repeated surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower peak pulse power (400 W), same DO-214AC package but different footprint and thermal resistance | Not AEC-Q101 qualified; intended for commercial-grade consumer power supplies | Select SMAJ10A only for cost-sensitive non-automotive designs where 600 W surge margin is not required |
| 1.5KE10A | Higher VC (16.7 V), larger DO-201AD package, 1500 W rating but higher leakage (50 µA @ VWM) | Used in industrial motor drives where PCB space permits larger case and higher clamping is acceptable | Choose 1.5KE10A when board layout allows DO-201AD and system can tolerate higher clamping voltage |
Compared with SMAJ10A and 1.5KE10A, the P6KA10AHE3/54 uniquely combines AEC-Q101 qualification, 600 W capability in DO-204AC, and 10 µA leakage at 150 °C - making it the only option validated for high-temperature automotive power rail protection without footprint or thermal compromise.

FAQ
What is the maximum clamping voltage of the P6KA10AHE3/54 at its rated peak pulse current?
The P6KA10AHE3/54 has a maximum clamping voltage (VC) of 14.5 V at its rated peak pulse current (IPPM) of 41.4 A, measured using the standard 10/1000 µs waveform. This value ensures that downstream components experience no more than 14.5 V during worst-case surge events, directly supporting design margin calculations for 12 V automotive systems. The P6KA10AHE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KA10AHE3/54 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6KA10AHE3/54 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 20-Dec-13 (Document Number: 88368). It undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and surge life validation - making it approved for use in engine control units, body control modules, and other under-hood automotive systems. The P6KA10AHE3/54 carries the HE3 suffix indicating RoHS compliance and JESD 201 Class 2 whisker resistance.
What is the stand-off voltage (VWM) and why is it critical for P6KA10AHE3/54 circuit design?
The stand-off voltage (VWM) of the P6KA10AHE3/54 is 8.55 V, representing the maximum continuous DC or RMS voltage the device can withstand without exceeding 10 µA reverse leakage. This parameter is critical because it must exceed the normal operating voltage of the protected line - for example, a nominal 12 V automotive rail with ±10 % tolerance (10.8 V max) requires careful system-level margining. The P6KA10AHE3/54's 8.55 V VWM is thus best applied on regulated 9 V or 8.5 V subrails, or with additional upstream filtering.
How does the temperature coefficient of VBR affect the P6KA10AHE3/54 in high-ambient environments?
The P6KA10AHE3/54 has a VBR temperature coefficient of +0.073 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At +150 °C, VBR rises by ~10.5 %, shifting from 9.5–10.5 V at 25 °C to approximately 10.5–11.6 V. This behavior ensures the P6KA10AHE3/54 remains non-conductive during elevated ambient operation while still triggering reliably during transients - a key advantage over alternatives with higher coefficients or negative drift.
What package type does the P6KA10AHE3/54 use and what are its mechanical advantages?
The P6KA10AHE3/54 uses the DO-204AC (DO-15) axial package: 9.5 mm body length, 3.6 mm diameter, with 25.4 mm minimum lead length. Its molded epoxy case meets UL 94 V-0 flammability rating, and matte tin-plated leads ensure solderability per J-STD-002. This compact, through-hole package offers superior thermal transfer to PCB copper compared to SMD variants and supports manual rework - critical for prototyping and low-volume automotive subsystem builds where the P6KA10AHE3/54 is commonly deployed.
