Product details
Overview
P6KA36HE3/54 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 32.4 V minimum breakdown voltage (VBR), 29.1 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 11.5 A peak pulse current (IPPM), and 185 °C maximum junction temperature - deployed in automotive engine control units to clamp load-dump transients.
For engineers reviewing the P6KA36HE3/54 datasheet, P6KA36HE3/54 pinout, P6KA36HE3/54 application, or P6KA36HE3/54 equivalent, key selection criteria include clamping voltage (52.0 V at IPPM), unidirectional polarity, DO-204AC (DO-15) package compatibility, AEC-Q101 qualification, and thermal stability up to 185 °C junction temperature.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, leveraging passivated anisotropic rectifier technology to achieve fast response (<1 ns) and low incremental surge resistance. Its unidirectional configuration allows forward conduction during positive overvoltage events while blocking reverse leakage below 1.0 μA at VWM.
The device is rated for 600 W peak pulse power under standardized 10/1000 μs waveform conditions and maintains stable clamping performance across -65 °C to +185 °C operating junction temperature range - validated per AEC-Q101 stress test requirements including high-temperature operating life and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V - ensures reliable triggering above normal 24 V rail operation while accommodating manufacturing tolerance |
| VWM | 29.1 V - maximum continuous reverse voltage before significant leakage; compatible with 24 V automotive systems |
| VC @ IPPM | 52.0 V - clamping voltage limits downstream IC stress during 11.5 A transient; critical for MOSFET gate protection |
| IPPM | 11.5 A - peak surge current handling capability under 10/1000 μs waveform; supports ISO 7637-2 Pulse 1 & 2a |
| TJ max. | +185 °C - enables placement near hot components (e.g., power inductors, ECUs) without derating concerns |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 9.5 mm body length; RoHS-compliant matte tin leads |
| AEC-Q101 | Qualified - certified for automotive applications including engine control, body electronics, and ADAS subsystems |
Pinout & Package
DO-204AC (DO-15) molded epoxy package with axial leads; cathode denoted by color band on body; terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to lower-potential side (e.g., ground or return path); enables unidirectional surge shunting |
| Cathode | Reverse-biased terminal during normal operation | Connected to protected line (e.g., 24 V rail); triggers avalanche conduction when VAK exceeds VBR |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply inputs in engine control units against ISO 7637-2 load-dump pulses (up to 60 V, 100 ms). IC Role / Device Role / Timing Role: Unidirectional TVS diode placed in parallel with input filter capacitor to clamp overvoltage before it reaches DC/DC converters and MCU power pins. Use Value: Limits peak voltage to 52.0 V during 11.5 A transients, preventing damage to 36 V-rated input stages of PMICs and regulators. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) connected to PLC analog input modules in factory automation. IC Role / Device Role / Timing Role: Low-capacitance TVS on signal line to absorb ESD and switching noise from nearby solenoid drivers without distorting mV-level signals.

IC Role / Device Role / Timing Role: Fast-response unidirectional suppressor placed between connector and PD controller's overvoltage detection circuit. Use Value: 52.0 V clamping voltage stays below 57 V absolute maximum rating of common PD controllers, avoiding latch-up or permanent failure. |
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-E3/5A | Same DO-214AC (SMA) package; 36 V VWM, 58.1 V VC @ 10.3 A; lower IPPM (10.3 A vs. 11.5 A) | Surface-mount alternative; requires PCB rework; better suited for space-constrained consumer designs | Select when board area is constrained and SMT assembly is preferred over through-hole DO-15 |
| 1.5KE36A | Higher PPPM (1500 W), larger DO-201AD package; 36 V VWM, 58.1 V VC @ 25.8 A; not AEC-Q101 qualified | Higher energy handling but lacks automotive qualification; used in industrial power supplies where qualification isn't required | Select only for non-automotive applications needing higher surge margin and no AEC-Q101 mandate |
Compared with SMAJ36A-E3/5A and 1.5KE36A, the P6KA36HE3/54 offers AEC-Q101 qualification, DO-204AC through-hole compatibility, and optimized thermal performance up to 185 °C - making it the preferred choice for automotive under-hood deployments where reliability and thermal resilience are mandatory.

FAQ
What is the maximum clamping voltage of the P6KA36HE3/54 under standard test conditions?
The P6KA36HE3/54 has a maximum clamping voltage (VC) of 52.0 V when subjected to its rated peak pulse current (IPPM = 11.5 A) using the 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components remain within safe operating voltage ranges.
Is the P6KA36HE3/54 suitable for automotive applications?
Yes, the P6KA36HE3/54 is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature, making it suitable for under-hood automotive applications including engine control units, transmission control modules, and body control modules. Its DO-204AC package and matte tin leads meet automotive solderability and whisker resistance requirements per JESD 201 Class 2.
What does the "HE3/54" suffix indicate in P6KA36HE3/54?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements. The "/54" indicates packaging in 13-inch diameter paper tape and reel with a base quantity of 4000 units - standard for automated SMT and through-hole assembly lines.
How does the P6KA36HE3/54 differ from the P6KA36A variant?
The P6KA36HE3/54 corresponds to the standard P6KA36 variant (VBR min/max = 32.4 V / 39.6 V), whereas P6KA36A has tighter VBR tolerance (34.2 V / 37.8 V). Both share identical VWM (30.8 V), IPPM (12.0 A), and VC (49.9 V), but P6KA36HE3/54 offers broader breakdown range - advantageous where design margin must accommodate wider system voltage tolerances.
What is the reverse leakage current specification for the P6KA36HE3/54 at maximum operating temperature?
At VWM = 29.1 V and TJ = 150 °C, the P6KA36HE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss and signal interference in always-on automotive modules, even under elevated thermal stress conditions typical in engine bay installations.
