Product details
Overview
P6KA36AHE3/73 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 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 DC-DC converter input stages.
For engineers reviewing the P6KA36AHE3/73 datasheet, P6KA36AHE3/73 pinout, P6KA36AHE3/73 application, or P6KA36AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, DO-15 package compatibility, low 1.0 μA leakage at VWM, and verified clamping performance under repetitive 0.01% duty cycle transients.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation up to TJ = 185 °C. Its unidirectional polarity and DO-204AC (DO-15) package support direct integration into 24 V and 36 V automotive and industrial power domains where fast response (<1 ns) and low incremental surge resistance are critical for MOSFET and IC protection.
The device meets ANSI/IEEE C62.35 surge waveform standards and is characterized for 10/1000 μs peak pulse power dissipation. Its thermal derating curve (Fig. 2) and power dissipation limit of 5.0 W on infinite heatsink define safe continuous operating boundaries when used with PCB copper pour or minimal thermal relief.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - ensures reliable triggering above 30.8 V system operating voltage while avoiding false trips during normal transients |
| VWM | 30.8 V - maximum continuous reverse voltage before significant leakage; matches nominal 36 V rail systems with margin |
| VC @ IPPM | ≤49.9 V - clamping voltage limits downstream component stress during 12.0 A surge events |
| IPPM | 12.0 A - peak surge current capability under standardized 10/1000 μs waveform at 0.01% duty cycle |
| TJ max. | +185 °C - enables use in under-hood automotive locations and high-ambient industrial enclosures without derating loss |
| Leakage @ VWM | 1.0 μA - negligible standby power loss and minimal impact on high-impedance sensor bias networks |

| Passivated anisotropic rectifier structure | Delivers stable VBR drift <0.099 %/°C and consistent surge response over lifetime and temperature |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

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-E3/5AT | Same VWM (30.8 V), lower PPPM (400 W), SMA package (surface-mount) | Requires PCB rework for SMT layout; lacks AEC-Q101 qualification | Select when board space is constrained and automotive qualification is not required |
| 1.5KE36A | Higher VC (58.1 V), same DO-15 package, 1500 W rating but larger footprint and higher leakage (5.0 μA) | Less effective clamping margin for 36 V systems; suitable only where higher VC is acceptable | Select only if legacy 1.5KE footprint must be retained and clamping voltage margin >22 V is tolerable |
Compared with SMAJ36A-E3/5AT and 1.5KE36A, P6KA36AHE3/73 delivers superior clamping (49.9 V vs. 58.1 V), automotive qualification, and tighter leakage (1.0 μA), making it optimal for new 36 V designs requiring high-reliability surge immunity in compact axial form.

FAQ
What is the maximum clamping voltage of the P6KA36AHE3/73 under rated surge conditions?
The P6KA36AHE3/73 has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated 12.0 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and guarantees that protected downstream components experience no more than 49.9 V during transient events, providing critical headroom for 36 V system components.
Is the P6KA36AHE3/73 qualified for automotive applications?
Yes, the P6KA36AHE3/73 is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. It meets automotive reliability requirements including temperature cycling, highly accelerated life testing, and surge immunity per ISO 7637-2 - making it suitable for engine control units, battery management systems, and ADAS power domains where long-term stability under thermal stress is essential.
What is the leakage current specification for P6KA36AHE3/73 at its stand-off voltage?
At its 30.8 V stand-off voltage (VWM), the P6KA36AHE3/73 exhibits a maximum reverse leakage current of 1.0 μA at TA = 25 °C. This ultra-low leakage ensures minimal power loss in always-on systems and avoids loading effects on high-impedance sensor bias networks or precision voltage references in applications such as industrial automation and telecom power monitoring.
Does the P6KA36AHE3/73 have a bidirectional configuration option?
No, the P6KA36AHE3/73 is available in uni-directional polarity only, as confirmed in the Vishay datasheet. The cathode is marked by a color band on the DO-15 package. For bidirectional protection needs, engineers must select alternate part numbers such as P6SMB36A or SMBJ36CA - neither of which share the same AEC-Q101 qualification or 185 °C rating as the P6KA36AHE3/73.
What is the package type and lead finish of P6KA36AHE3/73?
The P6KA36AHE3/73 uses the DO-204AC (DO-15) axial-leaded package with a 9.5 mm body length and UL 94 V-0 compliant epoxy molding. Its leads are matte tin plated and qualified for soldering per J-STD-002 and JESD 22-B102, including 275 °C solder dip for 10 seconds maximum - supporting both wave and selective soldering processes in high-volume manufacturing.
