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 225V, max 275V), 600W peak pulse power rating at 10/1000μs, clamping voltage of 360V at 1.7A peak surge current, and low dynamic impedance for effective overvoltage clamping in automotive and industrial control systems.
For engineers reviewing the P6KE250CA datasheet, P6KE250CA pinout, P6KE250CA application, or P6KE250CA equivalent, key selection criteria include its bidirectional DO-15 package configuration, 202V stand-off voltage (VWM), <1μA reverse leakage at rated VWM, AEC-Q101 qualification eligibility, and compliance with IEC 61000-4-5 surge immunity requirements.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds its breakdown threshold (225–275V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its bidirectional symmetry enables protection against both positive and negative polarity transients without polarity-sensitive placement.
Designed for 10/1000μs double-exponential surge waveforms per ANSI/IEEE C62.35, the P6KE250CA sustains 600W non-repetitive peak pulse power with thermal derating above 25°C ambient and junction temperature limits up to +175°C. Its fast response time (<5ns for bidirectional mode) ensures clamping before sensitive ICs experience overstress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 250 V - defines center of breakdown range; used for part-numbering and initial system voltage compatibility screening |
| Breakdown Voltage VBR | 225–275 V at 1 mA - actual avalanche onset range; determines minimum overvoltage level at which clamping initiates |
| Stand-off Voltage VWM | 202 V - maximum continuous reverse voltage the device blocks without significant leakage; sets upper limit for protected line operating voltage |
| Clamping Voltage VC | 360 V at 1.7 A IPP - maximum voltage seen by protected circuit during full-rated surge; critical for ensuring downstream component voltage ratings are not exceeded |
| Peak Pulse Power PPK | 600 W at 10/1000 μs - energy-handling capacity for standardized lightning/surge transients; defines single-event robustness |
| Reverse Leakage ID | <1 μA at 202 V - minimal power loss and signal interference during normal operation; supports low-power and high-impedance circuits |
| Junction Temperature TJ | −55°C to +175°C - operational thermal range enabling use in under-hood automotive, industrial motor drives, and outdoor power electronics |
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 (unmarked end) | Current entry point in forward bias; cathode band side is reference | Bidirectional symmetry means either lead serves as anode or cathode depending on transient polarity; no fixed polarity assignment required |
| Cathode (banded end) | Current exit point in forward bias; marking identifies terminal orientation | Band denotes conventional cathode; for bidirectional use, band position has no functional impact but aids visual orientation during manual assembly |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification option | Available with "H" suffix variant; validates reliability for automotive powertrain and body electronics applications requiring extended temperature cycling and humidity testing |
| Low dynamic impedance | Enables tight clamping ratio (VC/VBR ≈ 1.33) and rapid voltage stabilization during surge events, minimizing overshoot stress on protected ICs |
| Fast bidirectional response | <5 ns turn-on time ensures clamping activation before most microsecond-scale transients reach peak amplitude |
| UL recognition | UL File #E-326243 confirms compliance with UL 497B for telecom and industrial surge protection applications |
| Halogen-free construction | Meets IEC 61249-2-21; eliminates brominated flame retardants for RoHS-compliant and environmentally controlled manufacturing environments |

FAQ
What is the clamping voltage of P6KE250CA at its rated peak surge current?
The P6KE250CA has a maximum clamping voltage (VC) of 360 V at a peak pulse current (IPP) of 1.7 A, measured under the standard 10/1000 μs waveform. This value represents the highest voltage that will appear across the protected circuit during a full-rated 600W surge event, ensuring downstream components with ≥400V rating remain within safe operating limits. The P6KE250CA maintains this clamping performance across its specified junction temperature range.
Is P6KE250CA unidirectional or bidirectional, and how does the "CA" suffix indicate this?
The "CA" suffix in P6KE250CA explicitly denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike "A"-suffixed unidirectional variants, P6KE250CA has no designated anode or cathode for functional operation-either lead may serve as input or return depending on transient polarity. This eliminates orientation sensitivity during manual or automated assembly.
Does P6KE250CA meet AEC-Q101 qualification, and what does the "A0G" ordering code signify?
P6KE250CA itself is not automatically AEC-Q101 qualified; qualification requires the "H" suffix (e.g., P6KE250CAH). The "A0G" in P6KE250CA A0G indicates packaging in 1,500-unit ammo boxes and confirms RoHS-compliant, halogen-free construction per IEC 61249-2-21-but does not imply automotive qualification. Engineers requiring AEC-Q101 must specify P6KE250CAH and verify test reports for their lot.
How does the stand-off voltage (VWM) of P6KE250CA relate to system operating voltage selection?
The P6KE250CA has a stand-off voltage (VWM) of 202 V, meaning it reliably blocks voltages up to this level with <1 μA leakage. For reliable operation, the continuous DC or peak AC voltage on the protected line must remain below 202 V-typically derated by 10–20% for margin. Thus, P6KE250CA is suited for 170–200 VDC systems like telecom −48 V feeds with high-voltage transients or 24 V industrial buses with boosted surge thresholds.
Can P6KE250CA be used in parallel for higher surge current handling?
No-P6KE250CA is not recommended for parallel connection due to mismatch in dynamic impedance and avalanche characteristics, which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a single higher-rated device (e.g., 1.5KE350CA) or implement staged protection with upstream MOVs and downstream low-capacitance TVS arrays. The P6KE250CA is optimized for discrete, single-device placement per protected node.
