Product details
Overview
P6KE250CA from Taiwan Semiconductor is a bidirectional 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), 600W peak pulse power rating at 10/1000μs, clamping voltage of 360V at 1.7A peak surge current, and DO-204AC (DO-15) axial package - deployed in automotive power supply input stages to absorb load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE250CA datasheet, P6KE250CA pinout, P6KE250CA application, or P6KE250CA equivalent, key selection criteria include bidirectional clamping behavior, 360V VC@IPP, AEC-Q101 qualification status, thermal derating above 25°C, and compatibility with 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE250CA operates as a silicon avalanche diode with symmetrical bidirectional clamping - no polarity marking required. Its junction exhibits low dynamic impedance (<1Ω typical) and sub-nanosecond response time (<5ns from 0V to VBR), enabling effective suppression of fast transients including EFT (IEC 61000-4-4) and lightning-induced surges.
It is rated for non-repetitive peak impulse power of 600W at TA = 25°C, derated linearly to zero at 175°C junction temperature. The device sustains 1.7A peak surge current (IPP) at 10/1000μs while limiting voltage to ≤360V, and maintains <1μA reverse leakage at its 202V stand-off voltage (VWM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 202 V - Maximum continuous reverse operating voltage before significant leakage; defines safe DC rail margin below clamping threshold. |
| VBR (min/max) | 225 V / 275 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on across production lot and temperature. |
| VC @ IPP | 360 V @ 1.7 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream circuitry. |
| PPK | 600 W - Peak pulse power handling at 10/1000μs waveform; validates suitability for ISO 7637-2 Pulse 5a/b (load dump) events. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments with minimal thermal derating. |
| Package | DO-204AC (DO-15) - Axial-leaded, through-hole package with UL 94V-0 molding compound; compatible with standard wave-soldering processes. |
Pinout & Package
DO-204AC (DO-15) axial package with unmarked cathode band - bidirectional configuration means both terminals are functionally identical; no anode/cathode distinction required in circuit layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Surge current path terminal | Either lead conducts avalanche current during positive or negative transients; no polarity-sensitive placement needed. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without external polarity management. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - required for powertrain and body control modules. |
| 600W 10/1000μs surge rating | Meets ISO 7637-2 Pulse 5a (load dump) energy requirements up to 12V system level with margin. |
| Low clamping ratio (VC/VBR ≈ 1.33) | Minimizes overvoltage overshoot relative to breakdown threshold - critical for protecting 250V-rated capacitors and MOSFETs. |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive - supports green manufacturing and end-of-life recycling compliance. |

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 SMAJ250CA | Same 250V nominal, 600W rating, DO-214AC (SMA) surface-mount package; 350V VC@IPP vs. 360V. | Requires PCB rework for SMT assembly; better thermal dissipation in high-density layouts but lower surge endurance at elevated ambient. | Select when automated assembly and space constraints outweigh through-hole robustness requirements. |
| ON Semiconductor 1.5KE250CA | Same DO-204AC package and 250V rating, but 1500W peak power (10/1000μs); higher IPP (7.5A) and VC (390V). | Over-spec'd for most 600W-class systems; introduces unnecessary cost and larger board footprint without clamping benefit. | Choose only if legacy design uses 1.5KE series and board layout cannot accommodate revised thermal or voltage margin analysis. |
Compared with SMAJ250CA and 1.5KE250CA, the P6KE250CA offers optimal balance of axial-mount ruggedness, AEC-Q101 qualification, and precise 360V clamping - making it preferred for automotive and industrial through-hole designs where reliability and waveform fidelity are prioritized over raw power rating.

FAQ
What is the clamping voltage of P6KE250CA and how is it measured?
The P6KE250CA has a maximum clamping voltage (VC) of 360 V at 1.7 A peak pulse current (IPP), tested with a 10/1000 μs double-exponential surge waveform per IEC 61000-4-5. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events, and is guaranteed across the full operating temperature range of −55°C to +175°C. The P6KE250CA achieves this clamping performance via controlled avalanche breakdown in its symmetrical silicon junction.
Is P6KE250CA AEC-Q101 qualified and what tests does that include?
Yes, the P6KE250CA is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's certification documentation for the P6KE-H series. Qualification includes stress testing for high-temperature reverse bias (HTRB), temperature cycling (−40°C to +125°C, 1000 cycles), mechanical shock, and highly accelerated life testing (HALT). The "H" suffix in ordering codes (e.g., P6KE250CAH) denotes AEC-Q101 compliance; standard P6KE250CA also meets the specification per TSC's product family documentation.
How does P6KE250CA differ from unidirectional P6KE250A?
The P6KE250CA is bidirectional, meaning it clamps voltage symmetrically for both polarities - ideal for AC lines, floating signals, or systems where polarity reversal is possible. In contrast, P6KE250A is unidirectional with a cathode band marking and only clamps in reverse bias; forward conduction follows standard diode behavior. Both share identical VBR (225–275 V), VWM (202 V), and VC (360 V), but P6KE250CA eliminates need for polarity-aware layout and supports dual-polarity surge suppression with one device.
What is the maximum steady-state power dissipation for P6KE250CA at 75°C ambient?
The P6KE250CA 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 per terminal. This rating assumes natural convection cooling and reflects thermal limits of the DO-204AC package. At 25°C ambient, PD remains 5 W; derating begins linearly above 75°C and reaches zero at +175°C junction temperature - consistent with its TJ(max) = 175°C absolute maximum rating.
Can P6KE250CA be used in parallel for higher surge current handling?
No, P6KE250CA should not be paralleled for increased surge current capacity. Due to manufacturing variations in VBR (225–275 V), mismatched avalanche turn-on causes current hogging - one device absorbs disproportionate energy and fails prematurely. For higher IPP requirements, select a single higher-rated device (e.g., 1.5KE250CA) or implement staged protection with upstream current-limiting impedance. The P6KE250CA is characterized and validated only for standalone operation per its published electrical specifications.
