Product details
Overview
P6KA15AHE3/73 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 12.8 V stand-off voltage (VWM), 14.3–15.8 V breakdown voltage (VBR at 1 mA), 600 W peak pulse power (10/1000 μs), 28.3 A peak pulse current (IPPM), and clamps to ≤21.2 V at rated surge - deployed in automotive power supplies, industrial sensor interfaces, and MOSFET gate protection circuits.
For engineers reviewing the P6KA15AHE3/73 datasheet, P6KA15AHE3/73 pinout, P6KA15AHE3/73 application, or P6KA15AHE3/73 equivalent, key selection criteria include unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, 185 °C junction temperature rating, and clamping performance under 10/1000 μs transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive surge stress. Its unidirectional architecture provides low forward voltage (3.5 V @ 50 A) and fast response time to protect downstream ICs from inductive switching spikes and ESD-like transients.
Rated for operation from –65 °C to +185 °C, it supports high-reliability automotive and industrial environments where thermal derating and long-term stability are critical. The device complies with ANSI/IEEE C62.35 and meets JESD 201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 12.8 V - maximum continuous reverse voltage before conduction begins; sets operating margin below breakdown |
| VBR (Breakdown Voltage) | 14.3–15.8 V @ 1 mA - precise avalanche initiation threshold ensuring predictable clamping onset |
| VC (Clamping Voltage) | ≤21.2 V @ 28.3 A - limits transient voltage seen by protected circuitry during 10/1000 μs surge |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized lightning/surge immunity testing per IEC 61000-4-5 |
| TJ max. | +185 °C - enables use in under-hood automotive modules and high-ambient industrial controllers |
| IFSM (Surge Current) | 75 A @ 8.3 ms half-sine - withstands high-energy inductive turn-off events without failure |
| Polarity | Unidirectional - protects against positive-going transients only; cathode marked by band |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating; matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / surge return path | Connected to ground or low-impedance return in unidirectional clamp configuration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | Same VWM (12.8 V), identical DO-214AA package; 600 W rating but lower IPPM (32.4 A) and higher VC (24.4 V) | Less effective clamping margin in high-current surge scenarios; better suited for space-constrained PCBs | Select when board area is limited and peak surge currents remain below 25 A |
| 1.5KE15A | Higher VC (25.1 V), larger DO-201AD package, same 600 W rating; not AEC-Q101 qualified | Lacks automotive qualification and thermal robustness; suitable for commercial/industrial use only | Choose for cost-sensitive non-automotive designs where 185 °C operation is unnecessary |
Compared with SMBJ15A and 1.5KE15A, P6KA15AHE3/73 delivers tighter clamping (21.2 V vs. ≥24.4 V), guaranteed AEC-Q101 compliance, and superior high-temperature stability - making it the preferred choice for automotive and mission-critical industrial systems requiring validated reliability.

FAQ
What is the clamping voltage of P6KA15AHE3/73 at its rated peak pulse current?
The P6KA15AHE3/73 clamps to a maximum of 21.2 V when subjected to its rated peak pulse current of 28.3 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see no more than this voltage during surge events, directly supporting robust system-level EMC compliance.
Is P6KA15AHE3/73 suitable for automotive applications?
Yes, P6KA15AHE3/73 is AEC-Q101 qualified and rated for operation from –65 °C to +185 °C, making it suitable for under-hood and powertrain applications. Its passivated junction, JESD 201 Class 2 whisker resistance, and validated surge endurance meet stringent automotive reliability requirements.
What does the "HE3" suffix indicate in P6KA15AHE3/73?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads, solderable per J-STD-002 and JESD 22-B102, and passing JESD 201 Class 2 whisker testing. It confirms compliance with environmental and reliability standards required for high-reliability electronics manufacturing.
How does P6KA15AHE3/73 differ from the non-"A" variant P6KA15?
P6KA15AHE3/73 has a tighter breakdown voltage range (14.3–15.8 V) versus P6KA15 (13.5–16.3 V), resulting in more consistent clamping behavior and reduced unit-to-unit variation. It also exhibits lower maximum reverse leakage (1.0 μA vs. 1.0 μA at VWM, same spec) and improved temperature coefficient stability.
Can P6KA15AHE3/73 be used in bidirectional protection circuits?
No, P6KA15AHE3/73 is unidirectional only, with a single avalanche junction oriented to clamp positive transients on the cathode side. For bidirectional protection, a pair of P6KA15AHE3/73 devices in series-opposed configuration or a dedicated bidirectional TVS such as P6SMB15CA must be used.
