Product details
Overview
P6KE36AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 36V nominal breakdown voltage (VBR min/max: 34.2V–37.8V), 30.8V stand-off voltage (VWM), clamps to ≤49.9V at 12.6A peak surge current, and delivers sub-nanosecond response (<1.0ps) with <1μA leakage above 10V. It is AEC-Q101 qualified and used in automotive body control modules for ESD and load-dump suppression.
For engineers reviewing the P6KE36AH datasheet, P6KE36AH pinout, P6KE36AH application, or P6KE36AH equivalent, this page provides verified electrical parameters, DO-204AC package details, clamping behavior under 10/1000μs transients, AEC-Q101 qualification status, and direct alternatives for automotive-grade TVS selection.
Technical Context
The P6KE36AH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its specified VBR range (34.2–37.8V at 1mA test current). Its low dynamic impedance ensures rapid voltage clamping during fast transients such as ISO 7637-2 pulse 1 and pulse 2b.
It is rated for non-repetitive 600W peak pulse power (10/1000μs waveform), with thermal derating above 25°C ambient and maximum junction temperature of 175°C. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 34.2–37.8 V at IT = 1 mA - defines reliable avalanche initiation window for consistent clamping onset |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA |
| VC @ IPP | ≤49.9 V at IPP = 12.6 A - peak clamped voltage during 10/1000μs surge, limiting downstream stress |
| PPK | 600 W - peak pulse power handling per single 10/1000μs transient, critical for load-dump immunity |
| IR @ VWM | <1 μA - ultra-low leakage preserves battery life and signal integrity in always-on circuits |
| TJ max | +175 °C - enables operation in under-hood automotive environments without thermal shutdown |
| Response time | <1.0 ps - near-instantaneous turn-on ensures protection against ESD and fast-rising transients |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Dimensions conform to JEDEC DO-15 standard: overall length 4.2–5.2 mm, body diameter 2.3–2.7 mm, lead diameter 0.6–0.8 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

IC Role / Device Role / Timing Role: Reverse-biased TVS across driver output to absorb ESD (IEC 61000-4-2 ±15kV contact) and switching noise. Use Value: Sub-1ps response and <1μA leakage preserve driver efficiency and enable fail-safe operation during EMC testing. | Use Scenario: Front-end surge suppression on -48V telecom power distribution boards subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on -48V return path to clamp positive-going transients relative to chassis ground. Use Value: 600W rating and 175°C junction rating ensure reliability in sealed, high-temperature telecom cabinets. |
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; 36V VBR (34.2–37.8V), 49.9V [email protected], but rated 400W (not 600W) | Lower peak power rating limits suitability for automotive load dump; better for board-level ESD only | Select P6KE36AH when 600W 10/1000μs compliance is mandatory per OEM spec |
| ON Semiconductor 1.5KE36A | DO-201AD package; identical 36V VBR and 49.9V VC, but rated 1500W (10/1000μs) and higher IPP (38.4A) | Larger footprint and higher surge capacity suit industrial power supplies, not space-constrained automotive PCBs | Choose 1.5KE36A where layout allows larger package and >600W headroom is required |
Compared with SMAJ36A and 1.5KE36A, the P6KE36AH uniquely balances AEC-Q101 qualification, DO-15 compactness, and exact 600W capability-making it optimal for cost-sensitive, space-limited automotive modules requiring certified surge robustness.

FAQ
What is the clamping voltage of P6KE36AH and how is it measured?
The P6KE36AH has a maximum clamping voltage (VC) of 49.9 V, measured at a peak pulse current (IPP) of 12.6 A using the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and reflects worst-case voltage seen by downstream circuitry during surge events, ensuring compatibility with 50V-tolerant ICs.
Is P6KE36AH suitable for bidirectional transient protection?
No, P6KE36AH is a unidirectional TVS diode intended for DC line protection with defined polarity. For bidirectional applications (e.g., AC lines or data buses), use the P6KE36CA variant, which features symmetrical breakdown in both directions and lacks a cathode band marking.
Does P6KE36AH meet AEC-Q101 requirements, and what tests does that include?
Yes, P6KE36AH is AEC-Q101 qualified. Certification includes stress tests for high-temperature operating life (HTOL), temperature cycling (TC), highly accelerated stress test (HAST), mechanical shock, and ESD (HBM ≥8kV, CDM ≥1kV), confirming reliability for automotive under-hood deployment.
What is the maximum steady-state power dissipation for P6KE36AH at 75°C ambient?
The P6KE36AH has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This derates linearly to zero at 175°C junction temperature, supporting thermal design in enclosed automotive enclosures.
How does the leakage current of P6KE36AH compare to other 36V TVS diodes?
P6KE36AH exhibits ≤1 μA reverse leakage current at its 30.8 V stand-off voltage (VWM), measured at 25°C. This is comparable to industry-standard 36V TVS devices and significantly lower than older-generation parts, minimizing standby power loss in battery-backed systems and preserving signal integrity in high-impedance sensor interfaces.
