Product details
Overview
P6KE250C from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and signal interfaces. It features a nominal breakdown voltage of 250V, clamps transients to ≤360V at 1.7A peak pulse current, and delivers sub-nanosecond response time (<5.0ns) with low dynamic impedance - deployed in automotive lighting control modules and industrial PLC I/O protection circuits.
For engineers reviewing the P6KE250C datasheet, P6KE250C pinout, P6KE250C application, or P6KE250C equivalent, key selection criteria include its DO-204AC (DO-15) package compatibility, bidirectional clamping symmetry, 202V stand-off voltage, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE250C operates as a silicon avalanche diode configured in bidirectional mode, enabling symmetrical clamping for AC-coupled or floating signal paths. Its junction structure supports 600W non-repetitive peak pulse power per 10/1000μs waveform and maintains stable VBR (225–275V) with ±5% tolerance at 1mA test current.
Thermal performance is rated for continuous operation from –55°C to +175°C junction temperature, with derating applied above 25°C ambient per Fig.2. The device exhibits <1μA reverse leakage at 202V (VWM) and a temperature coefficient of VBR at 0.110%/°C - critical for high-temperature industrial sensor interface designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 10/1000μs waveform - sustains single high-energy surges without failure in lightning-prone environments |
| Breakdown Voltage VBR | 225–275V min/max at 1mA - defines precise clamping onset threshold for 250V nominal systems |
| Stand-off Voltage VWM | 202V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage VC | ≤360V at 1.7A IPP - limits downstream IC stress during surge events |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package compatible with legacy through-hole assembly |
| Response Time | <5.0ns (bidirectional) - ensures suppression activation before transient energy damages sensitive inputs |
| AEC-Q101 Qualified | Yes (H-suffix variants only; P6KE250C includes H per ordering code P6KE250CH) - validated for automotive under-hood applications |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with UL 94V-0 flammability rating and pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction terminals | No polarity marking required; identical clamping behavior in both directions - simplifies PCB layout for AC or floating nodes |
Key Features
| Feature | Design Value |
|---|---|
| 600W surge capability | Enables protection against IEC 61000-4-5 Level 4 (4kV/2Ω) surges without derating in standard PCB layouts |
| Low dynamic impedance | Minimizes voltage overshoot during fast-rising transients (e.g., EFT bursts), preserving signal integrity |
| Sub-5ns response time | Activates before most microsecond-scale transients fully develop - critical for protecting high-speed analog front-ends |
| AEC-Q101 qualified (H variant) | Validated for automotive powertrain and body electronics where temperature cycling and vibration reliability are mandatory |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive - supports green manufacturing and export 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 DO-214AC package; 600W rating; VBR = 278–308V (higher threshold); VC = 410V @ 1.5A | Less aggressive clamping - better suited for systems with higher margin between operating and damage thresholds | Select when tighter VBR tolerance (±5%) and lower clamping voltage (360V vs. 410V) are prioritized over package footprint reduction |
| Vishay 1.5KE250CA | Higher 1500W rating; DO-201AD package; VBR = 263–289V; VC = 360V @ 4.2A | Designed for higher-energy surges; larger thermal mass but incompatible pin spacing | Choose for legacy 1.5kW surge requirements where board space allows DO-201AD mounting and layout revision is feasible |
Compared with Littelfuse SMAJ250CA and Vishay 1.5KE250CA, the P6KE250C offers the lowest clamping voltage at its rated surge current (360V), tighter VBR tolerance (±10% vs. ±11.5%), and AEC-Q101 qualification in the compact DO-15 form factor - making it optimal for space-constrained automotive and industrial control designs requiring precise voltage limiting.

FAQ
What is the exact breakdown voltage range for P6KE250C?
The P6KE250C has a guaranteed breakdown voltage (VBR) range of 225V to 275V at 1mA test current, measured per ANSI/IEEE C62.35 standards. This ±10% tolerance ensures consistent clamping onset across production lots and supports reliable design margining in 240–250V nominal systems where the P6KE250C is commonly applied.
Is P6KE250C unidirectional or bidirectional?
P6KE250C is a bidirectional TVS diode, indicated by the "C" suffix per TSC's ordering nomenclature. It provides symmetrical clamping in both polarities - essential for protecting AC-coupled signals, floating grounds, or differential buses where polarity reversal may occur during surge events.
Does P6KE250C meet AEC-Q101 reliability standards?
Yes - the P6KE250C is AEC-Q101 qualified when ordered with the "H" suffix (e.g., P6KE250CH), as confirmed in TSC's ordering information. This qualification covers temperature cycling, mechanical shock, humidity testing, and high-temperature operating life - validating suitability for automotive under-hood and chassis-mounted applications.
What is the maximum clamping voltage of P6KE250C at rated surge current?
The P6KE250C clamps to a maximum of 360V at its rated peak pulse current of 1.7A (IPP), defined under the 10/1000μs waveform. This value represents the worst-case voltage seen by downstream circuitry during a full-rated surge event and is critical for ensuring connected ICs remain within absolute maximum ratings.
Can P6KE250C be used in place of P6KE250A?
No - P6KE250C and P6KE250A are not interchangeable. P6KE250A is unidirectional (anode/cathode marked), while P6KE250C is bidirectional (no polarity marking). Substituting one for the other risks incorrect clamping behavior in AC or floating circuits, potentially leading to unprotected transients or forward conduction failure in DC applications.
