Product details
Overview
P6KA36AHE3/54 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 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 12.0 A peak pulse current (IPPM), and clamps to 49.9 V at rated surge - deployed in automotive power rails, industrial sensor interfaces, and MOSFET gate protection circuits.
For engineers reviewing the P6KA36AHE3/54 datasheet, P6KA36AHE3/54 pinout, P6KA36AHE3/54 application, or P6KA36AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-204AC (DO-15) package compatibility, and verified clamping performance under repetitive 10/1000 μs transients in high-reliability embedded systems.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, leveraging passivated anisotropic rectifier technology to deliver stable breakdown behavior across temperature. Its 0.099 %/°C VBR temperature coefficient ensures predictable threshold drift up to +185 °C junction temperature.
The device is optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of inductive switching spikes and ESD events on DC power inputs and low-voltage control lines. It meets JESD22-B102 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines reliable avalanche conduction onset range under 1.0 mA test current |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 49.9 V - clamping voltage at 12.0 A peak pulse, limiting protected circuit stress during surge |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform, supporting automotive load-dump immunity |
| TJ max. | +185 °C - enables operation in under-hood automotive and high-temperature industrial environments |
| AEC-Q101 | Qualified - validated for automotive electronic modules per stress test requirements |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with UL 94 V-0 molded epoxy |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking; leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, rated for 275 °C/10 s solder dip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional clamp configuration |
| Cathode | Avalanche conduction terminal | Connected to protected line (e.g., 24 V rail); color band identifies this end for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|

| Fast transient response | Sub-nanosecond response time ensures clamping activation before sensitive downstream components experience overvoltage |
| Low clamping ratio | VC/VBR ≈ 1.32 - tight voltage margin between breakdown and clamping improves system-level surge margin |
| Robust surge handling | Withstands 75 A non-repetitive forward surge (8.3 ms half-sine), protecting against inrush and fault currents |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per AEC standard |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5BT | Same VWM (30.8 V) and VC (49.9 V), but SMA package (surface-mount), lower IPPM (11.7 A), 400 W PPPM | Preferred for space-constrained PCBs; not suitable for through-hole or high-vibration mechanical mounting | Select when board area is limited and reflow assembly is used; verify mechanical retention for shock/vibe environments |
| 1.5KE36A | Higher PPPM (1500 W), larger DO-201 package, same VWM/VBR range, but no AEC-Q101 qualification | Used in industrial power supplies where automotive qualification is not required and higher surge margin is needed | Choose for non-automotive 1500 W surge needs; avoid where AEC-Q101 or 185 °C operation is mandatory |
Compared with SMAJ36A-E3/5BT and 1.5KE36A, the P6KA36AHE3/54 uniquely combines AEC-Q101 qualification, 185 °C operation, and DO-204AC mechanical robustness - making it the preferred choice for automotive and high-reliability industrial through-hole designs requiring proven long-term stability.

FAQ
What is the breakdown voltage range for P6KA36AHE3/54?
The P6KA36AHE3/54 has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures consistent avalanche initiation across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is P6KA36AHE3/54 qualified for automotive use?
Yes, P6KA36AHE3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. Its 185 °C maximum junction temperature and DO-204AC construction meet automotive under-hood environmental requirements.
What is the clamping voltage of P6KA36AHE3/54 at its rated peak pulse current?
The P6KA36AHE3/54 clamps to a maximum of 49.9 V at its rated peak pulse current of 12.0 A (10/1000 μs waveform). This value is measured per standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events.
Does P6KA36AHE3/54 have unidirectional or bidirectional polarity?
P6KA36AHE3/54 is unidirectional only, with a clearly marked cathode band indicating the terminal to be connected toward the protected line. It conducts in reverse-bias avalanche mode during overvoltage and blocks up to 30.8 V in normal operation - no symmetrical bidirectional capability is provided.
What package type does P6KA36AHE3/54 use, and what are its key mechanical attributes?
P6KA36AHE3/54 uses the DO-204AC (DO-15) axial package: molded epoxy body meeting UL 94 V-0, matte tin-plated leads compliant with J-STD-002, and rated for 275 °C/10 s solder dip. The cathode band provides unambiguous polarity identification for manual and automated assembly.
