Product details
Overview
P6KE250AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 250V nominal breakdown voltage (VBR min/max: 225V–275V), 202V standoff voltage (VWM), clamps to ≤360V at 1.7A peak surge current, and operates within –55°C to +175°C junction temperature range. It is AEC-Q101 qualified and housed in DO-204AC (DO-15) package for automotive-grade reliability.
For engineers reviewing the P6KE250AH datasheet, P6KE250AH pinout, P6KE250AH application, or P6KE250AH equivalent, key selection criteria include its 202V working voltage, 360V clamping performance under 10/1000μs surge, AEC-Q101 qualification status, DO-15 mechanical compatibility, and low leakage (<1μA @ 202V) - all critical for robust overvoltage protection in automotive ECUs and industrial power supplies.
Technical Context
The P6KE250AH employs a silicon avalanche diode structure optimized for fast response (<1.0ps rise time from 0V to VBR) and low dynamic impedance to minimize voltage overshoot during transients. Its unidirectional configuration provides asymmetric conduction: low forward voltage drop in normal operation and rapid reverse avalanche clamping above VWM.
It is rated for 600W non-repetitive peak pulse power (10/1000μs waveform), derated linearly above 25°C ambient per JEDEC JESD22-A103, with maximum junction temperature of 175°C and thermal resistance (RθJA) of ~80°C/W on 5×5 mm copper pads. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 202 V - Maximum continuous reverse voltage before significant leakage; defines safe operating DC bias level. |
| VBR (Breakdown Voltage) | 225–275 V - Measured at 1 mA IT; ensures reliable avalanche initiation within specified tolerance band. |
| VC @ IPPM (Clamping Voltage) | ≤360 V @ 1.7 A - Peak voltage seen by protected circuit during full-rated 10/1000μs surge; determines system-level overvoltage margin. |
| PPK (Peak Pulse Power) | 600 W - Energy-handling capacity for single 10/1000μs transient; defines surge immunity level per IEC 61000-4-5. |
| IR @ VWM (Reverse Leakage) | <1 μA @ 202 V - Negligible standby power loss and minimal loading on upstream circuitry. |
| TJ max (Junction Temp) | +175 °C - Enables use in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress test conditions including HTOL, TC, HAST, and UHAST. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with cathode band marking. Dimensions: 4.2 mm diameter × 7.2 mm length; weight ≈ 0.400 g. Leads are pure tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward conduction terminal | Connects to lower-potential side (e.g., ground or return path); conducts during forward-biased operation. |
| Cathode (banded end) | Avalanche clamping terminal | Connects to protected line (e.g., 24V rail); initiates controlled reverse breakdown when voltage exceeds VWM. |
Key Features

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 SMAJ250A | Same 250V nominal, DO-214AC (SMA) package; 400W rating; higher thermal resistance (~120°C/W). | Lower surge rating and different footprint require PCB redesign; suitable only where space constraints favor surface-mount. | Select if SMT assembly is mandatory and 400W surge margin suffices; not drop-in for through-hole DO-15 layouts. |
| ON Semiconductor 1.5KE250A | Same 250V rating, DO-201AD package; 1500W rating; larger case (5.6×9.5mm); higher clamping voltage (≤410V @ 3.7A). | Higher power handling but slower response (>1.0ps) and incompatible mechanical fit; requires larger board area. | Choose for higher-energy surges where clamping voltage margin allows; not mechanically or thermally interchangeable with P6KE250AH. |
Compared with Littelfuse SMAJ250A and ON Semi 1.5KE250A, the P6KE250AH uniquely balances AEC-Q101 qualification, 600W capability, DO-15 through-hole compatibility, and 360V clamping - making it optimal for automotive and industrial through-hole designs demanding validated reliability and precise voltage limiting.

FAQ
What is the clamping voltage of the P6KE250AH under full-rated surge conditions?
The P6KE250AH clamps to a maximum of 360 V when subjected to its rated 1.7 A peak pulse current (IPP) under the standard 10/1000 μs waveform. This value is measured at 25°C and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events, ensuring downstream components rated for ≥360V withstand stress.
Is the P6KE250AH suitable for bidirectional surge protection?
No, the P6KE250AH is a unidirectional TVS diode, indicated by the "H" suffix (AEC-Q101 qualified unidirectional variant). For bidirectional protection, Taiwan Semiconductor offers the P6KE250CA - which uses a center-tapped dual-diode configuration and carries a "CA" suffix. Using P6KE250AH in bidirectional applications risks failure due to forward conduction during negative transients.
How does the AEC-Q101 qualification of the P6KE250AH impact its use in automotive designs?
The AEC-Q101 qualification of the P6KE250AH confirms it has passed accelerated stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST), validating its suitability for under-hood and cabin automotive applications. This eliminates need for additional qualification testing when used in ECU, lighting, or ADAS subsystems per ISO/TS 16949 requirements.
What is the maximum steady-state power dissipation for the P6KE250AH at 75°C ambient?
The P6KE250AH has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C with 9.5 mm lead lengths, as specified in its Absolute Maximum Ratings table. This value assumes mounting on 5 × 5 mm copper pads per terminal and defines the continuous thermal limit - not to be confused with its 600W non-repetitive surge rating.
Can the P6KE250AH be used in parallel to increase surge current handling?
No - paralleling P6KE250AH devices is not recommended due to mismatch in VBR (225–275V range) causing uneven current sharing and potential thermal runaway. For higher surge capability, select a higher-rated part such as the 1.5KE250A (1500W) or implement staged protection with upstream GDTs and downstream TVS arrays designed for current balancing.
