Product details
Overview
P6KE36CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in power supply input stages and automotive electronics. It features a nominal breakdown voltage of 36 V, maximum clamping voltage of 52.0 V at 12.0 A peak surge current, 175°C junction temperature rating, and DO-204AC (DO-15) axial package - used to protect DC/DC converters, ECU power rails, and industrial sensor interfaces against IEC 61000-4-5 surges.
For engineers reviewing the P6KE36CH datasheet, P6KE36CH pinout, P6KE36CH application, or P6KE36CH equivalent, key selection criteria include its AEC-Q101 qualification, 10/1000 µs waveform surge capability, low dynamic impedance (<1 Ω typical), sub-1 ps response time from 0 V to VBR, and compliance with UL 94V-0 and RoHS/halogen-free standards.
Technical Context
The P6KE36CH operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 32.4–39.6 V breakdown range (VBR) at 1 mA test current. Its clamping action limits transient energy to ≤52.0 V at 12.0 A (10/1000 µs), enabling robust protection of downstream MOSFETs and controllers without crowbar behavior.
Thermal design relies on its 175°C max junction temperature and 5 W steady-state dissipation at 75°C ambient (with 9.5 mm lead length). The device exhibits <1 µA reverse leakage above 30.8 V stand-off voltage (VWM), ensuring minimal standby power loss in always-on systems such as automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 32.4–39.6 V at 1 mA - defines reliable turn-on threshold across temperature and unit variation |
| VWM | 30.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 52.0 V at 12.0 A (10/1000 µs) - peak clamped voltage seen by protected IC during worst-case surge |
| PPK | 600 W - non-repetitive surge power handling per IEC 61000-4-5 Level 4 testing |
| TJMAX | 175°C - enables operation in under-hood automotive environments and high-ambient industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400 g mass and tin-plated leads per J-STD-002 |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance. Polarity is marked via cathode band; anode and cathode terminals are not interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for clamping | Connected to system ground or low-side return path; establishes reference for reverse-biased avalanche operation |
| Cathode (banded end) | Transient sink terminal | Connected to protected line (e.g., +12 V rail); conducts surge current to ground when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTGB, TC, and AC-H3TRB |
| 600 W surge rating (10/1000 µs) | Withstands IEC 61000-4-5 Level 4 (4 kV) surges without degradation in automotive 12 V/24 V systems |
| Clamping voltage ≤52.0 V | Ensures protected ICs (e.g., MCU power pins, gate drivers) remain below absolute maximum ratings during transients |
| Response time <1.0 ps | Activates before most microsecond-scale transients fully develop, preventing latch-up or oxide damage in CMOS devices |
| UL 94V-0 & halogen-free | Meets flame-retardant and environmental compliance for enclosed automotive and industrial assemblies |
Applications
| Automotive Power Rail Protection | Industrial DC/DC Input Stage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Same DO-214AC package; 36 V nominal, 58.1 V clamping at 10.3 A; 400 W rating | Lower surge rating suits consumer-grade 24 V systems but insufficient for automotive load dump | Select SMAJ36A only if 400 W peak power suffices and AEC-Q101 is not required |
| ON Semiconductor 1.5KE36C | DO-201AD package; 36 V nominal, 58.1 V clamping at 10.3 A; 1500 W rating; bidirectional | Bidirectional configuration supports AC-coupled lines; larger footprint requires PCB rework | Choose 1.5KE36C only when bidirectional protection or higher 1500 W surge margin is mandatory |
Compared with P6KE36CH, SMAJ36A offers smaller footprint but lacks AEC-Q101 validation and 600 W surge headroom, while 1.5KE36C delivers higher power handling and bidirectional capability at the cost of larger DO-201AD packaging and no automotive qualification.

FAQ
What is the maximum clamping voltage of the P6KE36CH under standard surge conditions?
The P6KE36CH has a maximum clamping voltage (VC) of 52.0 V when subjected to a 10/1000 µs waveform at 12.0 A peak surge current. This value is measured per ANSI/IEEE C62.35 and ensures protected downstream components remain within safe operating voltage limits during standardized surge events. The P6KE36CH maintains this clamping performance across its full operating temperature range.
Is the P6KE36CH suitable for automotive applications requiring AEC-Q101 certification?
Yes, the P6KE36CH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code. It has undergone full stress testing including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated life testing - making it suitable for under-hood and chassis-mounted automotive systems such as body control modules and power distribution units.
How does the P6KE36CH differ from the P6KE36A variant?
The P6KE36CH is the AEC-Q101-qualified, unidirectional version with tighter VBR tolerance (34.2–37.8 V) and same 52.0 V clamping as P6KE36A, whereas P6KE36A is commercial-grade and lacks automotive qualification. Both share DO-204AC packaging and identical electrical specs except for reliability validation - P6KE36CH is intended for mission-critical automotive use, while P6KE36A targets industrial or consumer applications.
What is the reverse leakage current specification for the P6KE36CH at its stand-off voltage?
The P6KE36CH exhibits a maximum reverse leakage current (ID) of 1 µA at its rated stand-off voltage (VWM) of 30.8 V, measured at 25°C. This low leakage ensures minimal power loss in always-on circuits such as automotive wake-up receivers or industrial sensor nodes operating continuously from battery or backup supplies.
Can the P6KE36CH be used in bidirectional signal line protection?
No, the P6KE36CH is a unidirectional TVS diode and must not be used on AC or bidirectional signal lines. Its cathode-band marking indicates polarity-sensitive operation; reverse connection will cause forward conduction and failure. For bidirectional protection, select the CA-suffixed variant (e.g., P6KE36CA) or a dedicated bidirectional TVS like P6KE36C - both explicitly rated for symmetrical clamping in either direction.
