Product details
Overview
P4KE10C from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 10V nominal standoff voltage, 9.0–11.0V breakdown range at 1mA test current, 8.1V working voltage, and clamps transients to ≤15.0V at 28A peak pulse current - deployed in automotive body control modules, industrial PLC I/O protection, and AC/DC adapter input stages.
For engineers reviewing the P4KE10C datasheet, P4KE10C pinout, P4KE10C application, or P4KE10C equivalent, key selection criteria include its DO-41 package compatibility, unidirectional polarity marking, 175°C junction rating, low 1μA leakage at 8.1V, and AEC-Q101 qualification option - critical for ESD and EFT immunity in harsh-environment electronics.
Technical Context
The P4KE10C operates as a silicon avalanche diode with fast response (<1.0ps rise time from 0V to VBR) and low dynamic impedance, enabling effective clamping of 10/1000μs surge waveforms up to 400W. Its unidirectional architecture provides forward conduction capability (VF = 3.5V @ 25A) while blocking reverse leakage below 1μA at rated VWM.
Thermal performance is defined by a 175°C maximum junction temperature and derated power dissipation above 25°C ambient, with mechanical robustness ensured by UL 94V-0 molding compound and pure tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 10 V - defines rated standoff level before avalanche onset |
| Breakdown Voltage (VBR) | 9.0–11.0 V @ 1 mA - ensures reliable triggering within tight tolerance band |
| Working Standoff Voltage (VWM) | 8.1 V - maximum continuous reverse voltage without significant leakage |
| Clamping Voltage (VC) | ≤15.0 V @ 28 A - limits downstream circuit stress during 10/1000μs surges |
| Peak Pulse Power (PPK) | 400 W - supports high-energy transient suppression per IEEE C62.35 |
| Junction Temperature Range | −55°C to +175°C - enables operation in under-hood automotive and industrial environments |
| Leakage Current (ID) | <1 μA @ 8.1 V - minimizes standby power loss in battery-powered systems |

Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
Use Scenario: Protects MCU GPIO and CAN transceiver power rails from load dump and alternator ripple in 12V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and ground to clamp transients before they reach LDO regulators and interface ICs. Use Value: Limits voltage excursions to ≤15.0V during 100V/400ms load dump events, preserving system uptime and preventing latch-up in 3.3V/5V logic. |
Use Scenario: Shields 24V digital input channels from inductive kickback generated by solenoid and relay coils. IC Role / Device Role / Timing Role: Primary-level surge absorber on field-side input traces, upstream of optocoupler or Schmitt trigger conditioning circuits. Use Value: Absorbs 400W energy from 10/1000μs spikes without failure, eliminating false triggering and extending input stage MTBF beyond 10 years. |
| AC/DC Adapter Input Stage | LED Driver Power Supply |
Use Scenario: Guards bridge rectifier output and bulk capacitor from line surges and lightning-induced transients in Class II power supplies. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC bus to clamp overvoltage before it stresses primary-side controller ICs and MOSFETs. Use Value: Clamps 1kV/0.5J surges to <15V, preventing premature failure of 600V-rated switching components and meeting IEC 61000-4-5 Level 3 requirements. |
Use Scenario: Safeguards constant-current LED driver ICs from voltage reversals and flyback spikes during hot-plug or dimmer switching. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; P4KE10C used unidirectionally across driver output to absorb negative-going transients from inductive loads. Use Value: Maintains LED string integrity by limiting reverse voltage to <1V during turn-off, avoiding junction breakdown in series-connected LEDs. |
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 P4KE10A | Tighter VBR tolerance (9.5–10.5V vs. 9.0–11.0V); same DO-41 package and 400W rating | Preferred where tighter clamping consistency is required across production lots | Select P4KE10A when VBR variation must be minimized for precision threshold detection circuits |
| ON Semiconductor 1N6267A | Same 10V nominal rating but lower PPK (300W); identical DO-41 footprint and unidirectional polarity | Suitable for cost-sensitive consumer applications with lower surge exposure | Choose 1N6267A only if system-level surge testing confirms 300W margin is sufficient |
Compared with P4KE10C, P4KE10A offers improved VBR consistency at the expense of slightly reduced minimum breakdown voltage, while 1N6267A trades 25% lower surge capacity for broader commercial availability - making P4KE10C the optimal balance of ruggedness, tolerance, and automotive-grade readiness.

FAQ
What is the maximum clamping voltage of the P4KE10C under standard test conditions?
The P4KE10C exhibits a maximum clamping voltage (VC) of 15.0 V when subjected to a 10/1000μs waveform at its rated peak pulse current of 28 A. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components experience no more than 15.0 V during such transients - a critical parameter for protecting 3.3V or 5V logic interfaces. The P4KE10C maintains this clamping performance across its full operating temperature range.
Is the P4KE10C suitable for bidirectional transient protection?
No, the P4KE10C is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical characteristics - including breakdown voltage, leakage, and clamping - apply only in reverse-biased mode, with forward conduction limited to 3.5 V at 25 A. For bidirectional protection, the P4KE10CA variant (with "CA" suffix) must be selected, as confirmed in the Taiwan Semiconductor P4KE series documentation.
Does the P4KE10C meet automotive reliability standards?
The base P4KE10C is not AEC-Q101 qualified; however, the P4KE10CH variant (with "H" suffix) is explicitly certified to AEC-Q101 for stress tests including temperature cycling, high-temperature reverse bias, and accelerated life testing. Engineers designing for automotive applications should specify P4KE10CH to ensure compliance with automotive quality and reliability requirements.
What is the thermal derating behavior of the P4KE10C above 25°C ambient?
The P4KE10C's peak pulse power rating remains at 400 W up to 25°C ambient, then linearly derates to zero at 175°C junction temperature. Steady-state power dissipation is rated at 1 W at 75°C lead temperature, with derating curves provided in Figure 2 of the official datasheet. Designers must account for PCB copper area and airflow to maintain TJ ≤ 175°C during repetitive surge events.
How does the P4KE10C compare to the P4KE10A in terms of breakdown voltage tolerance?
The P4KE10C has a breakdown voltage range of 9.0–11.0 V at 1 mA test current, while the P4KE10A narrows this to 9.5–10.5 V - reflecting tighter process control. Both share identical package, surge rating, and clamping voltage. The P4KE10C's wider VBR spread accommodates cost-sensitive industrial designs, whereas P4KE10A suits applications demanding precise threshold stability, such as comparator-based overvoltage detectors.
