Product details
Overview
P4KE10 from Taiwan Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 10 V nominal breakdown voltage, 8.10 V working stand-off voltage, 15.0 V maximum clamping voltage at 28.0 A peak pulse current, and 400 W peak pulse power rating per 10/1000 µs waveform - deployed in automotive lighting control modules to safeguard microcontroller I/O pins against load dump and ESD transients.
For engineers reviewing the P4KE10 datasheet, P4KE10 pinout, P4KE10 application, or P4KE10 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum ratings, leakage current at operating voltage, thermal derating under sustained ambient conditions, and DO-41 package compatibility with existing PCB layouts for retrofit protection upgrades.
Technical Context
The P4KE10 operates as a silicon avalanche diode with sharp reverse-breakdown characteristics, triggered when transient voltage exceeds its 9.00–11.00 V breakdown range at 1 mA test current. Its low dynamic impedance ensures rapid voltage clamping during fast-rising transients, with typical response time under 1.0 ps from 0 V to VBR.
Designed for unidirectional operation, it conducts only in reverse bias above VBR, blocking forward current up to 3.5 V at 25 A. The device sustains 40 A non-repetitive forward surge (8.3 ms half-sine) and operates across –55 °C to +175 °C junction temperature, meeting AEC-Q101 stress requirements when qualified.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.10 V - Maximum continuous reverse voltage before significant leakage; sets upper limit for safe DC rail operation |
| VBR @ IT=1 mA | 9.00–11.00 V - Confirmed avalanche onset range; defines minimum transient threshold for clamping activation |
| VC @ IPPM=28.0 A | 15.0 V - Clamped voltage during 400 W surge; must stay below protected IC's absolute max input rating |
| ID @ VWM | <10 µA - Low leakage ensures minimal power loss and signal integrity degradation in standby |
| PPK | 400 W - Peak pulse power handling per 10/1000 µs waveform; validates robustness against ISO 7637-2 Pulse 1/2/5a |
| TJ max | +175 °C - Enables placement near heat-generating components without thermal shutdown risk |
| Package | DO-204AL (DO-41) - Standard axial-leaded through-hole package; compatible with legacy wave-solder and hand-solder processes |
Pinout & Package
DO-204AL (DO-41) package: axial-leaded, glass-passivated silicon junction, cathode band marked on case. Leads are pure tin-plated, solderable per J-STD-002, with 0.300 g typical weight and UL 94V-0 molding compound.

Applications
| Automotive Lighting Control | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting MCU GPIO and CAN transceiver power rails in headlamp driver modules subjected to load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed directly at connector entry point to shunt >400 V spikes to ground within sub-nanosecond. Use Value: Prevents latch-up or permanent damage to 5 V logic interfaces by limiting rail voltage to ≤15.0 V during 100 V/500 ms load dump events. | Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers exposed to inductive kickback from solenoid switching. IC Role / Device Role / Timing Role: Standoff protector across input terminals, conducting only during >30 V transients while remaining high-impedance during normal operation. Use Value: Eliminates need for external series resistors or RC snubbers by providing <10 µA leakage and 15.0 V clamping at 28 A peak. |
| Consumer Power Adapter ESD Shielding | Telecom Line Interface Surge Suppression |
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters where 10 V-rated ICs interface with 9–15 V variable output rails. IC Role / Device Role / Timing Role: Fast-acting clamp between VBUS and GND, activated before internal LDO or USB controller reaches absolute maximum ratings.

IC Role / Device Role / Timing Role: First-stage TVS on differential pair, absorbing common-mode surges induced by lightning proximity or AC coupling. Use Value: Ensures signal integrity by limiting transient overshoot to ≤15.0 V while preserving <10 pF junction capacitance at 0 V bias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Surface-mount SMB package; 10 V standoff; 17.0 V clamping at 24.7 A; 600 W rating | Requires PCB redesign for SMT layout; better suited for high-density consumer electronics | Select when board space is constrained and reflow assembly is available |
| 1N6267 | Same DO-41 package; 10 V nominal; 15.0 V clamping at 28.0 A; 400 W rating; legacy industrial grade | No AEC-Q101 qualification; higher leakage (≤50 µA @ VWM) | Select for cost-sensitive industrial controls where automotive qualification is not required |
Compared with SMBJ10A and 1N6267, the P4KE10 offers identical clamping performance and through-hole compatibility but adds AEC-Q101 qualification and lower leakage - making it optimal for automotive and high-reliability industrial retrofits where pinout retention and qualification traceability are mandatory.

FAQ
What is the maximum clamping voltage of the P4KE10 under surge conditions?
The P4KE10 has a maximum clamping voltage (VC) of 15.0 V when subjected to its rated peak pulse current of 28.0 A under the standard 10/1000 µs waveform. This value is measured and guaranteed per the datasheet's electrical characteristics table and ensures protected circuitry remains within safe operating limits during transient events. The P4KE10 maintains this clamping performance across its full operating temperature range.
Is the P4KE10 suitable for automotive applications?
Yes - the P4KE10 is available in an AEC-Q101 qualified version (P4KE10H), validated for automotive use per stress test requirements including temperature cycling, humidity bias, and mechanical shock. While the base P4KE10 meets all electrical specifications, design-in for automotive systems requires specifying the 'H' suffix variant to ensure qualification traceability. The P4KE10H retains identical electrical parameters and DO-41 packaging.
What is the reverse leakage current of the P4KE10 at its working stand-off voltage?
The P4KE10 exhibits a maximum reverse leakage current (ID) of 10 µA when biased at its working stand-off voltage (VWM) of 8.10 V, measured at 25 °C. This low leakage supports energy-efficient designs, especially in battery-operated or always-on systems. Leakage remains below 50 µA up to +125 °C junction temperature, as confirmed in TSC's thermal derating curves.
Does the P4KE10 have polarity marking, and how is it identified?
Yes - the P4KE10 is a unidirectional TVS diode with explicit polarity marking: a cathode band (typically white or black) is printed on the DO-41 package body adjacent to the cathode lead. During PCB layout, the banded end must connect to the line being protected (e.g., 12 V rail), while the anode connects to ground. Incorrect orientation prevents clamping action and may result in catastrophic failure under overvoltage.
Can the P4KE10 be used in bidirectional configurations?
No - the P4KE10 is strictly unidirectional. For bidirectional transient suppression, TSC offers the P4KE10CA variant (with 'CA' suffix), which uses back-to-back diode construction to provide symmetrical clamping in both polarities. Substituting the P4KE10 in a bidirectional circuit will result in forward conduction during negative transients, potentially damaging downstream circuitry. Always verify part suffix: 'A' denotes tighter VBR tolerance, 'CA' denotes bidirectional, 'H' denotes AEC-Q101.
