Product details
Overview
P6KE250A from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge clamping in power and signal lines. It features a nominal breakdown voltage of 250 V, maximum clamping voltage of 344 V at 1.8 A peak pulse current, stand-off voltage of 214 V, and operates across -55°C to +175°C junction temperature range - deployed in automotive power supply rail protection and industrial sensor interface circuits.
For engineers reviewing the P6KE250A datasheet, P6KE250A pinout, P6KE250A application, or P6KE250A equivalent, key selection criteria include its DO-204AC (DO-15) axial package, unidirectional polarity with cathode band marking, 1.8 A peak surge current rating, and compliance with AEC-Q101 for automotive-grade reliability.
Technical Context
The P6KE250A employs a silicon avalanche diode structure optimized for fast transient suppression with sub-nanosecond response (<1.0 ps from 0 V to VBR). Its low dynamic impedance ensures stable clamping under 10/1000 µs surge waveforms, while the 0.110 %/°C temperature coefficient of VBR maintains predictable breakdown behavior across wide thermal ranges.
Designed for unidirectional operation only, it exhibits <1 µA reverse leakage at 214 V (VWM) and supports 100 A non-repetitive forward surge current (IFSM) per 8.3 ms half-sine wave - enabling robust protection against inductive switching transients and ESD events without forward conduction interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 237 V / 263 V at 1 mA test current - defines guaranteed avalanche onset window for reliable overvoltage triggering |
| VWM | 214 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPP | 344 V at 1.8 A peak pulse current - clamping voltage limiting downstream circuit stress during surge |
| PPK | 600 W at 10/1000 µs waveform - peak single-pulse energy absorption capability |
| IR @ VWM | <1 µA - minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max | +175 °C - enables use in under-hood automotive and high-temperature industrial environments |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking on one end; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: anode (unmarked end), cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry / surge return path | Connected to protected line's ground or low-side reference; completes clamping loop during transient |
| Cathode (banded end) | Avalanche voltage reference / clamping node | Connected to protected line input; initiates avalanche conduction when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| 600 W 10/1000 µs surge rating | Withstands high-energy lightning-induced surges and load dump transients without degradation |
| Clamping voltage ≤344 V at 1.8 A | Ensures downstream ICs rated for ≤350 V absolute maximum survive worst-case transients |
| Leakage <1 µA at 214 V | Preserves battery life and avoids false triggering in always-on monitoring circuits |
| Fast response <1.0 ps | Engages before transient edges propagate into sensitive analog or digital inputs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 24 V CAN bus power rails from ISO 7637-2 pulse 1 (inductive load dump) and pulse 3a/b (switching noise). IC Role / Device Role: Unidirectional TVS placed between VBAT and chassis ground to clamp negative transients and limit positive overshoot.

Use Scenario: Shielding 4–20 mA current-loop transmitters from ESD and field wiring transients in factory automation. IC Role / Device Role: TVS mounted across loop terminals to shunt >8 kV HBM ESD and 1 kV burst noise away from precision DAC and op-amp front-end. Use Value: Eliminates calibration drift and output lockup caused by transient-induced latch-up in analog signal conditioning ICs. |
| Lighting System Surge Suppression | Power Supply Input Stage Clamping |
|

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 DO-214AC (SMA) package; 344 V clamping at 1.8 A; 1.0 µA leakage at 214 V | Surface-mount footprint requires PCB redesign; lower thermal mass limits repetitive surge duty cycle | Select when space-constrained layouts favor SMD over axial components |
| ON Semiconductor 1.5KE250A | Same DO-204AC (DO-15) package; identical VBR, VWM, and VC; 1000 W peak power rating | Higher surge capacity suits infrequent but extreme transients (e.g., utility grid coupling); larger case may affect mechanical fit | Select when legacy 1.5KE-series qualification or higher single-pulse margin is required |
Compared with P6KE250A, SMAJ250A offers SMT compatibility at the cost of reduced thermal endurance, while 1.5KE250A provides 67% higher peak power handling in the same axial form factor - enabling trade-offs between board density, surge repetition rate, and absolute energy tolerance.

FAQ
What is the polarity configuration of the P6KE250A?
The P6KE250A is a unidirectional TVS diode with clearly marked cathode band on the DO-204AC (DO-15) package. It conducts only during reverse-biased overvoltage events - the banded end connects to the protected line, and the unmarked end connects to ground or low-side reference. This configuration prevents forward conduction during normal operation while enabling precise clamping above 237 V.
Does the P6KE250A meet AEC-Q101 requirements?
Yes, the P6KE250A is AEC-Q101 qualified per Taiwan Semiconductor's documentation (P2203 version). It undergoes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - validating suitability for automotive powertrain, body electronics, and ADAS subsystems where reliability under thermal and vibration stress is critical.
How does the P6KE250A compare to bidirectional variants like P6KE250CA?
The P6KE250A is unidirectional and not interchangeable with bidirectional types such as P6KE250CA. While both share identical VBR and VC values, the P6KE250CA clamps in both directions and lacks polarity marking. Using P6KE250A in place of P6KE250CA would leave positive transients unprotected; conversely, substituting P6KE250CA for P6KE250A introduces unnecessary forward conduction risk in DC-coupled lines.
What is the maximum ambient temperature for continuous operation of the P6KE250A?
The P6KE250A supports continuous operation up to +75°C ambient temperature at full rated power (5 W steady-state dissipation), with derating applied above that point per Figure 2 in the datasheet. Its junction temperature can reach +175°C, allowing use in high-temperature enclosures - but PCB layout must ensure adequate copper pad area (5 × 5 mm per lead) to maintain thermal performance.
Can the P6KE250A be used in parallel for higher surge current handling?
No - the P6KE250A is not recommended for parallel operation due to mismatch in VBR tolerance (237–263 V) and dynamic impedance. Uneven current sharing during transients risks thermal runaway in the lower-VBR unit. For higher IPP, select a single higher-rated device (e.g., 1.5KE250A) or verify matched binning and external balancing resistors per Taiwan Semiconductor's application guidance.
