Product details
Overview
P6KE36C from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 36 V, clamps transients to ≤52.0 V at 12.0 A peak surge current, and delivers fast response (<1.0 ps from 0 V to VBR), low dynamic impedance, and <1 µA reverse leakage above 30.8 V stand-off voltage. It is widely deployed in automotive body electronics and industrial power supply input stages.
For engineers reviewing the P6KE36C datasheet, P6KE36C pinout, P6KE36C application, or P6KE36C equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity marking, 175 °C maximum junction temperature, and compliance with AEC-Q101 (H-suffix variant) for automotive-grade reliability.
Technical Context
The P6KE36C operates as a silicon avalanche diode optimized for transient suppression using a single-die, unidirectional structure. Its clamping behavior follows the 10/1000 µs standard waveform, with a maximum clamping voltage of 52.0 V at 12.0 A peak pulse current and a temperature coefficient of VBR at 0.099 %/°C.
It exhibits low dynamic impedance enabling effective energy diversion during ESD and EFT events, and maintains <1 µA reverse leakage at its 30.8 V stand-off voltage. The device is rated for non-repetitive peak impulse power dissipation of 600 W and steady-state power dissipation of 5 W at 75 °C with specified PCB pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 32.4 V / 39.6 V - Ensures reliable avalanche conduction onset across temperature and process variation |
| VWM | 30.8 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage |
| VC @ IPP | 52.0 V @ 12.0 A - Clamping voltage under 10/1000 µs surge; defines protected circuit's worst-case overvoltage exposure |
| IR @ VWM | <1 µA - Minimal standby power loss and negligible loading on sensitive upstream circuits |
| PPK | 600 W - Peak transient energy handling capacity per single 10/1000 µs pulse |
| TJMAX | 175 °C - Enables operation in under-hood automotive and high-ambient industrial environments |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package with tin-plated leads, UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional polarity. Leads are pure tin-plated and solderable per J-STD-002; weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to circuit ground or lowest potential node; completes conduction path during transient clamp |
| Cathode | High-side surge input terminal | Connected to protected line (e.g., +12 V rail); avalanche breakdown initiates here when VAK exceeds VBR |
Key Features

Applications
| Automotive Power Rail Protection | Industrial DC Power Input |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs against load dump and jump-start surges. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontrollers.

IC Role / Device Role / Timing Role: Standoff protector on digital I/O lines interfacing with solenoids and relays. Use Value: Absorbs up to 600 W of surge energy while maintaining <1 µA leakage at 30.8 V, preserving signal integrity during normal operation. |
| LED Driver Overvoltage Clamp | ESD-Sensitive Interface Protection |
|
Use Scenario: Shielding constant-current LED driver ICs from flyback spikes generated by long cable runs or hot-plug events. IC Role / Device Role / Timing Role: Unidirectional shunt clamp on driver output rail, referenced to system ground.

IC Role / Device Role / Timing Role: Board-level TVS placed between bus line and ground, adjacent to connector. Use Value: Low clamping voltage ensures transceiver I/O remains below absolute maximum ratings during ±15 kV air discharge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ36A | Same DO-214AC (SMA) package; 36 V nominal, 58.1 V clamping at 10.3 A; 400 W rating | Lower surge rating and higher clamping voltage reduce margin for 600 W load dump events | Select when space-constrained SMT layout is required and peak surge energy is ≤400 W |
| ON Semiconductor 1.5KE36C | Same DO-204AC (DO-15) package; identical 36 V nominal, 52.0 V clamping at 12.0 A; 600 W rating; RoHS-compliant | Functionally interchangeable with P6KE36C in through-hole designs; minor parametric variance in tempco (0.099% vs 0.100%/°C) | Drop-in replacement where second-source assurance or alternate supply chain is needed |
Compared with SMAJ36A and 1.5KE36C, the P6KE36C offers identical clamping performance and surge rating in the same axial package as the latter, but provides superior thermal robustness (175 °C TJMAX) versus SMAJ36A's 150 °C limit-critical for under-hood automotive deployments.

FAQ
What is the polarity configuration of the P6KE36C?
The P6KE36C is a unidirectional TVS diode with clearly marked cathode band. It conducts only when the cathode is positive relative to the anode, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants (e.g., P6KE36CA), which suppress surges of either polarity without regard to terminal orientation. The P6KE36C must be installed with correct anode–cathode alignment to function as intended.
Does the P6KE36C meet AEC-Q101 qualification?
The P6KE36C itself is not AEC-Q101 qualified; only the P6KE36CH variant carries that certification. The "H" suffix denotes full AEC-Q101 stress testing per Rev D, including temperature cycling, humidity bias, and mechanical shock. For automotive under-hood applications requiring qualification evidence, P6KE36CH-not P6KE36C-must be specified and sourced. Both share identical electrical parameters and DO-15 packaging.
What is the maximum clamping voltage of the P6KE36C and at what test condition?
The P6KE36C has a maximum clamping voltage (VC) of 52.0 V, measured at a peak pulse current (IPP) of 12.0 A using the standardized 10/1000 µs double-exponential surge waveform. This value represents the worst-case voltage seen by downstream circuitry during a full-power transient event and is guaranteed across the full operating temperature range per the datasheet's electrical specifications table.
Can the P6KE36C be used in bidirectional signal line protection?
No-the P6KE36C is strictly unidirectional and unsuitable for AC or bidirectional signal lines such as RS-485 or USB D+/D−. Attempting to use it on a bidirectional line risks forward conduction during negative half-cycles, causing malfunction or damage. For such applications, the bidirectional P6KE36CA (or P6KE36CH for AEC-Q101) must be selected, as it provides symmetrical clamping in both directions with identical VBR and VC characteristics.
What is the standoff voltage (VWM) of the P6KE36C and why does it matter?
The P6KE36C has a maximum working peak reverse voltage (VWM) of 30.8 V, meaning it reliably blocks voltages up to this level with <1 µA leakage. This parameter ensures the device remains non-conductive during normal operation-critical for minimizing power loss and avoiding false triggering. Selecting a TVS with VWM too close to system operating voltage risks excessive leakage or premature breakdown; P6KE36C's 30.8 V VWM provides safe margin above common 24 V nominal rails.
