Product details
Overview
P4KA10HE3/54 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-204AL (DO-41) package, with 9.0–11.0 V breakdown voltage (VBR), 15.0 V clamping voltage (VC) at 26.7 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for under-hood electronics protection.
For engineers reviewing the P4KA10HE3/54 datasheet, P4KA10HE3/54 pinout, P4KA10HE3/54 application, or P4KA10HE3/54 equivalent, this part serves as a high-reliability, RoHS-compliant TVS for automotive sensor line surge suppression, MOSFET gate protection, and 12 V rail transient clamping where junction temperature up to +185 °C and low incremental surge resistance are required.
Technical Context
The P4KA10HE3/54 uses patented PAR® construction for stable clamping under repetitive transients and operates exclusively in unidirectional polarity, with cathode denoted by color band. Its 10/1000 µs waveform response delivers 26.7 A peak pulse current while maintaining 15.0 V clamping voltage - critical for protecting downstream ICs against ISO 7637-2 load dump surges.
Rated for continuous power dissipation of 1.5 W on infinite heatsink at TL = 75 °C and 40 A non-repetitive forward surge (8.3 ms half-sine), it supports high-temperature automotive environments with a -65 °C to +185 °C operating junction range and 0.073 %/°C VBR temperature coefficient.
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 |
|---|---|---|---|
| SMBJ10A-E3/52 (Vishay) | Surface-mount SMB package; same VBR range (9.0–11.0 V) but lower 1.0 kW PPPM rating; 1000 W vs. 400 W. | Designed for PCB space-constrained layouts; lacks axial lead mechanical robustness for high-vibration harness connections. | Select when automated SMT assembly is required and thermal mass from board copper suffices for energy absorption. |
| 1.5KE10A (ON Semiconductor) | Through-hole DO-201AE package; identical 400 W PPPM and 15.0 V VC, but rated only to +175 °C TJ and not AEC-Q101 qualified. | Approved for industrial/commercial use only; requires additional qualification testing for automotive deployment. | Acceptable for cost-sensitive non-automotive designs where AEC-Q101 is not mandated and 10 °C lower max junction temperature is acceptable. |
Compared with SMBJ10A-E3/52 and 1.5KE10A, the P4KA10HE3/54 uniquely combines AEC-Q101 qualification, +185 °C junction rating, and axial DO-41 mechanical stability - making it the only option qualified for direct integration into production automotive power distribution and sensor subsystems without requalification.

FAQ
What is the clamping voltage of the P4KA10HE3/54 at its rated peak pulse current?
The P4KA10HE3/54 has a maximum clamping voltage (VC) of 15.0 V at 26.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for 12 V automotive circuits. The P4KA10HE3/54 maintains this clamping performance across its full operating temperature range, supporting robust design margins in engine bay applications.
Is the P4KA10HE3/54 suitable for bidirectional transient suppression?
No, the P4KA10HE3/54 is unidirectional only, as confirmed in the Vishay datasheet Document Number 88364. It features a single cathode band and is designed to clamp positive transients on a line referenced to ground. For bidirectional protection, a separate symmetric TVS or back-to-back configuration would be required - the P4KA10HE3/54 itself does not support reverse-polarity surge suppression.
Does the P4KA10HE3/54 meet automotive qualification standards?
Yes, the P4KA10HE3/54 is AEC-Q101 qualified, explicitly noted in the "Mechanical Data" section of the Vishay datasheet. The HE3 suffix denotes high-reliability, automotive-grade construction, including JESD201 Class 2 whisker resistance and extended temperature validation. This makes the P4KA10HE3/54 suitable for production automotive applications including powertrain, chassis, and body electronics.
What is the maximum continuous reverse voltage the P4KA10HE3/54 can withstand?
The P4KA10HE3/54 has a maximum stand-off voltage (VWM) of 8.10 V, meaning it blocks up to this DC or RMS voltage without significant leakage (≤5.0 µA at 25 °C). This allows safe operation on nominal 12 V systems where normal operating voltage remains below 8.10 V - typical for regulated sub-rails or signal lines. The P4KA10HE3/54 begins clamping only when transients exceed its 9.0–11.0 V breakdown range.
How does the temperature coefficient affect the P4KA10HE3/54's breakdown voltage?
The P4KA10HE3/54 has a VBR temperature coefficient of +0.073 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At +150 °C, VBR rises ~10.5% above its 25 °C value - from 9.0–11.0 V to approximately 9.9–12.1 V. This predictable drift ensures stable clamping behavior across the full -65 °C to +185 °C operating range, and the P4KA10HE3/54 is characterized to maintain specification compliance throughout.
