Product details
Overview
P6KA15HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 12.1 V stand-off voltage (VWM), 13.5–16.3 V breakdown range (VBR at 1 mA), 600 W peak pulse power (10/1000 μs), 22.0 V maximum clamping voltage at 27.3 A, and operates up to +185 °C junction temperature - deployed in automotive engine control units, industrial PLC I/O modules, and telecom power supplies.
For engineers reviewing the P6KA15HE3/54 datasheet, P6KA15HE3/54 pinout, P6KA15HE3/54 application, or P6KA15HE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD tolerance, unidirectional polarity compatibility with DC-biased lines, AEC-Q101 qualification for automotive use, and DO-204AC (DO-15) leaded package thermal derating above 25 °C.
Technical Context
The P6KA15HE3/54 employs passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its junction design enables reliable operation at TJ = 185 °C and meets AEC-Q101 stress test requirements for automotive under-hood applications.
It delivers 600 W peak pulse power handling per 10/1000 μs waveform with 0.01 % duty cycle, clamping transients within 22.0 V at 27.3 A, and exhibits <1.0 μA reverse leakage at VWM (12.1 V) up to 150 °C - critical for low-power sensor interface protection where leakage-induced offset must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 12.1 V - Maximum continuous DC or RMS voltage the device blocks without clamping; sets upper limit for protected circuit operating voltage. |
| VBR (Breakdown Voltage) | 13.5–16.3 V at 1 mA - Voltage at which device enters avalanche conduction; defines onset of transient suppression. |
| VC (Clamping Voltage) | 22.0 V at IPPM = 27.3 A - Maximum voltage seen by downstream circuit during 600 W transient; determines safe margin for 15 V logic or MCU supply rails. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Energy-handling capability for standard lightning/surge waveforms; validates compliance with IEC 61000-4-5 Level 3. |
| TJ max. | +185 °C - Enables placement near heat sources (e.g., power MOSFETs, motor drivers) without derating failure risk. |
| AEC-Q101 Qualified | Yes - Confirmed reliability for automotive applications including engine control, body electronics, and ADAS power domains. |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with matte tin-plated leads, UL 94 V-0 molding, and JESD 201 Class 2 whisker resistance. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode indicated by color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, rated for solder dip ≤275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-voltage reference; completes current path during transient clamp event. |
| Cathode | High-side connection point | Connected to protected line (e.g., 12 V rail); polarity marking ensures correct orientation for unidirectional suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Optimized anisotropic rectifier process ensures stable VBR and low leakage across -65 °C to +185 °C. |
| High-temperature operation | Rated for continuous operation at TJ = 185 °C - eliminates need for oversized heatsinking in compact automotive modules. |
| Fast response time | Sub-nanosecond turn-on enables clamping before sensitive ICs experience overvoltage damage. |
| Low incremental surge resistance | Minimizes voltage overshoot during high-di/dt events (e.g., relay coil de-energization), improving clamping precision. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling - supports PPAP documentation. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Digital Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/5A (Vishay) | Same DO-214AC (SMA) package; lower PPPM = 400 W; VBR = 13.3–14.7 V; VC = 19.9 V at 20.1 A. | Lower power rating suits consumer-grade 24 V systems with less severe surge exposure; not AEC-Q101 qualified. | Select when space-constrained SMT layout is required and automotive qualification is unnecessary. |
| 1.5KE12A (ON Semiconductor) | DO-201AD package; same 600 W rating; VBR = 12.8–14.2 V; VC = 19.2 V at 31.3 A; no AEC-Q101 certification. | Larger case improves thermal dissipation but requires more board area; suitable for industrial power supplies with higher ambient temps. | Choose for cost-sensitive industrial designs where AEC-Q101 is not mandated and lead spacing allows DO-201AD footprint. |
Compared with SMAJ12A-E3/5A and 1.5KE12A, the P6KA15HE3/54 uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 185 °C operation - making it the only option among the three validated for under-hood automotive deployment with minimal thermal margin.

FAQ
What is the maximum clamping voltage of the P6KA15HE3/54 under a 600 W transient?
The P6KA15HE3/54 clamps to a maximum of 22.0 V at its rated peak pulse current of 27.3 A (10/1000 μs waveform). This value is measured per IEC 61000-4-5 test conditions and defines the worst-case voltage imposed on protected circuitry during surge events - critical for ensuring compatibility with 15 V-rated downstream ICs.
Is the P6KA15HE3/54 suitable for automotive applications?
Yes, the P6KA15HE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications such as engine control units, body control modules, and ADAS power domains where high ambient temperature and long-term reliability are required.
What does the HE3/54 suffix indicate in P6KA15HE3/54?
The HE3 suffix denotes RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The /54 indicates packaging in 13-inch paper tape and reel with a base quantity of 4000 units - standard for automated SMT assembly despite the device being through-hole.
How does the unidirectional polarity of P6KA15HE3/54 affect circuit placement?
The P6KA15HE3/54 is unidirectional and must be oriented with its cathode (marked by color band) toward the positive side of the protected line. It conducts only during reverse-bias overvoltage events - ideal for DC rails like 12 V or 24 V where forward conduction is not required and leakage must remain minimal.
What is the thermal derating behavior of P6KA15HE3/54 above 25 °C ambient?
The P6KA15HE3/54 follows a linear derating curve from 100 % power at 25 °C to 0 % at 175 °C (per Fig. 2 in datasheet 88368). At 100 °C ambient, its peak pulse power drops to ~65 % of 600 W (~390 W), and its steady-state power dissipation (PD) reduces from 5.0 W at TL = 75 °C per Fig. 5.
