Product details
Overview
P6KE12HE3/54 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 12 V breakdown voltage (VBR = 11.4–12.6 V at 1.0 mA), 16.7 V maximum clamping voltage at 35.9 A peak pulse current, 600 W peak pulse power rating (10/1000 µs), and AEC-Q101 qualification for automotive-grade reliability - deployed in engine control units, infotainment power inputs, and industrial sensor interfaces.
For engineers reviewing the P6KE12HE3/54 datasheet, P6KE12HE3/54 pinout, P6KE12HE3/54 application, or P6KE12HE3/54 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 10.2 V stand-off voltage (VWM), 5.0 µA max reverse leakage at VWM, 175 °C max junction temperature, and compliance with UL 497B surge protector recognition (QVGQ2).
Technical Context
The P6KE12HE3/54 operates as a silicon avalanche diode with glass-passivated junction, delivering bi-polar clamping action only in reverse-biased mode (uni-directional polarity). Its 20 °C/W junction-to-lead thermal resistance enables effective heat dissipation during transient events, while the 10/1000 µs waveform response ensures sub-nanosecond turn-on to suppress ESD and load-switching spikes before downstream ICs are damaged.
Designed for single-pulse and low-duty-cycle repetitive surges (0.01 % duty cycle), it sustains 100 A non-repetitive forward surge current (8.3 ms half-sine) and maintains stable clamping performance across -55 °C to +175 °C operating range - validated per AEC-Q101 stress test conditions including temperature cycling, HTRB, and ESD-HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V at 1.0 mA - defines precise avalanche initiation threshold for predictable overvoltage triggering |
| VWM | 10.2 V - maximum continuous working voltage before leakage exceeds 5.0 µA; sets safe DC rail margin |
| VC @ IPPM | 16.7 V at 35.9 A - clamping voltage under 600 W transient; limits downstream voltage stress to ≤16.7 V |
| PPPM | 600 W (10/1000 µs) - peak surge handling capacity for automotive load-dump and inductive kick events |
| TJ max | +175 °C - high-temperature operation supports under-hood automotive placement without derating |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with matte tin-plated leads, RoHS-compliant |
| Qualification | AEC-Q101 qualified - certified for automotive electronics per stress test requirements (HTSL, TCT, etc.) |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with axial leads; cathode indicated by color band on body. Matte tin-plated leads meet J-STD-002 solderability and JESD 22-B102 mechanical robustness standards. Lead length ≥25.4 mm, body diameter 2.6–3.6 mm, total length ≥7.6 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected circuit (e.g., GND or return path) |
| Cathode (banded end) | Avalanche clamping terminal | Connected to higher-potential line (e.g., 12 V rail); conducts when reverse voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/57T | Lower 400 W PPPM, SMA package (surface-mount), 13.3 V VC @ 32.3 A | Preferred for space-constrained PCBs; lacks AEC-Q101 qualification and UL 497B recognition | Select when board area is critical and automotive qualification is not required. |
| 1.5KE12A | Same DO-15 package, 600 W rating, but commercial-grade only (no AEC-Q101), 16.7 V VC @ 35.9 A | Valid for industrial/commercial use only; not approved for automotive under-hood deployment | Choose for cost-sensitive non-automotive designs where AEC-Q101 is unnecessary. |
Compared with SMAJ12A-E3/57T and 1.5KE12A, the P6KE12HE3/54 uniquely combines AEC-Q101 qualification, UL 497B recognition, and DO-15 through-hole robustness - making it the only option qualified for automotive power rail protection without layout redesign.

FAQ
What is the clamping voltage of the P6KE12HE3/54 under maximum surge conditions?
The P6KE12HE3/54 exhibits a maximum clamping voltage (VC) of 16.7 V when subjected to its rated peak pulse current of 35.9 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that downstream components see no more than 16.7 V during worst-case transients - a critical parameter for protecting 12 V logic and power ICs. The P6KE12HE3/54 maintains this clamping performance across its full operating temperature range.
Is the P6KE12HE3/54 suitable for automotive applications?
Yes, the P6KE12HE3/54 is AEC-Q101 qualified and specifically tested for automotive under-hood environments, including temperature cycling (-55 °C to +175 °C), high-temperature reverse bias, and mechanical shock. Its DO-204AC package and matte tin-plated leads meet automotive solderability and corrosion resistance requirements. The P6KE12HE3/54 is widely deployed in engine control modules, body control units, and infotainment power supplies.
How does the P6KE12HE3/54 differ from the standard P6KE12A variant?
The P6KE12HE3/54 differs from P6KE12A in three key ways: (1) HE3 suffix denotes AEC-Q101 qualification, whereas P6KE12A is commercial-grade only; (2) it carries UL 497B recognition (QVGQ2) for surge protector classification; and (3) it uses JESD 201 Class 2 whisker-resistant plating. All other electrical parameters - including VBR, VC, and PPPM - are identical between P6KE12HE3/54 and P6KE12A.
What is the maximum reverse leakage current for the P6KE12HE3/54 at its stand-off voltage?
The P6KE12HE3/54 has a maximum reverse leakage current (ID) of 5.0 µA at its stand-off voltage (VWM) of 10.2 V, measured at 25 °C. This low leakage ensures minimal power loss in always-on circuits and avoids false triggering in high-impedance sensor interfaces. Leakage remains below 10 µA up to 125 °C, supporting reliable operation in thermally demanding applications like automotive power distribution.
Can the P6KE12HE3/54 be used in bi-directional protection configurations?
No - the P6KE12HE3/54 is a uni-directional TVS diode, identified by its cathode band marking and specified breakdown behavior only in reverse bias. For bi-directional protection, Vishay offers the P6KE12CA variant (with CA suffix), which provides symmetrical clamping in both polarities. Using the P6KE12HE3/54 in bi-directional applications risks forward conduction and failure during positive transients; always match device polarity to circuit topology. The P6KE12HE3/54 must be oriented with cathode toward the protected high-side rail.
