Product details
Overview
P4KE11 from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 11 V, working stand-off voltage of 8.92 V, clamping voltage of 16.2 V at 26 A peak pulse current, and operates across -55°C to +175°C junction temperature range.
For engineers reviewing the P4KE11 datasheet, P4KE11 pinout, P4KE11 application, or P4KE11 equivalent, this device is selected for robust ESD and lightning surge immunity in automotive body electronics, industrial sensor interfaces, and AC/DC adapter input stages where low clamping ratio and fast sub-nanosecond response are critical.
Technical Context
The P4KE11 operates as a unidirectional avalanche diode with a defined cathode band marking. Its 10/1000 μs waveform surge rating of 400 W is achieved via silicon junction design optimized for low dynamic impedance and stable VBR tolerance (±10% min/max). The device exhibits <1.0 ps response time from 0 V to VBR, enabling effective suppression of fast-rising transients such as EFT and contact ESD.
It complies with AEC-Q101 stress test requirements when ordered with "H" suffix, supports 1 W steady-state dissipation at 75°C lead temperature, and maintains reverse leakage <1 μA at 8.92 V - ensuring minimal standby power loss in always-on circuits.
Key Specifications

Pinout & Package
DO-204AL (DO-41) package with axial leads; cathode identified by a single band on the body. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.

Applications
| Automotive Body Electronics | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting LIN bus transceivers and door module microcontrollers from load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 12 V supply rail upstream of LDO regulators and CAN/LIN PHYs. Use Value: Limits rail voltage to ≤16.2 V during 400 W surges, preventing latch-up or gate oxide damage in 16 V-rated ICs. | Use Scenario: Shielding 4–20 mA current loop receivers and RTD front-ends from field-induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Bidirectional-capable protection (via P4KE11CA variant) placed at connector entry point before signal conditioning op-amps. Use Value: Sub-ns response ensures clamping before transient energy couples into precision amplifier inputs, preserving measurement integrity. |
| AC/DC Adapter Input Stage | LED Driver Power Supply |
Use Scenario: Safeguarding bridge rectifier outputs and bulk capacitor charging paths against AC line surges and switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS connected between rectified DC+ and ground, absorbing positive-going transients only. Use Value: 8.92 V VWM allows reliable blocking of 12 V DC output while clamping 16.2 V peaks - ideal for 12 V adapter secondary-side protection. | Use Scenario: Protecting constant-current LED driver ICs from inductive kickback generated by MOSFET switching in buck topology. IC Role / Device Role / Timing Role: Clamp placed across high-side switch drain-source to absorb turn-off voltage spikes exceeding 12 V rail. Use Value: 26 A IPPM handles typical buck converter spike currents; 16.2 V clamping prevents driver IC overvoltage shutdown or failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11A | Surface-mount SMB package; 11 V standoff; 17.5 V clamping at 23.3 A; 600 W rating | Requires PCB redesign for SMT layout; better suited for space-constrained designs with higher surge margin | Select when board real estate is limited and 600 W surge headroom is required over P4KE11's 400 W |
| 1N6267 | Same DO-41 package; 11 V nominal; 16.5 V clamping at 24.2 A; 400 W rating; no AEC-Q101 option | Direct drop-in replacement in legacy through-hole designs but lacks automotive qualification path | Select for cost-sensitive industrial controls where AEC-Q101 compliance is not mandated |
Compared with SMBJ11A and 1N6267, the P4KE11 offers verified AEC-Q101 qualification (with H suffix), identical DO-41 footprint compatibility, and tighter VBR tolerance (±10%) - making it optimal for new automotive and high-reliability industrial designs requiring traceable qualification and proven thermal robustness up to 175°C.

FAQ
What is the maximum clamping voltage of P4KE11 under standard surge conditions?
The P4KE11 has a maximum clamping voltage (VC) of 16.2 V when subjected to its rated 26 A peak pulse current (IPPM) under the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during a 400 W transient event. The P4KE11 maintains this clamping performance across its full operating temperature range of -55°C to +175°C.
Is P4KE11 suitable for bidirectional transient protection?
No - the standard P4KE11 is unidirectional and intended for DC line protection with defined polarity (cathode marked). For bidirectional applications, the P4KE11CA variant must be used; it features symmetrical breakdown in both directions and is explicitly designated for AC or dual-polarity signal line protection. The P4KE11 itself conducts only in reverse bias above VBR and blocks forward current up to 3.5 V.
What is the reverse leakage current specification for P4KE11 at its working voltage?
The P4KE11 specifies a maximum reverse leakage current (ID) of 1 μA at its working stand-off voltage (VWM) of 8.92 V, tested at 25°C. This ultra-low leakage ensures minimal power loss in always-on systems such as automotive body controllers or IoT sensor nodes, where quiescent current budget is tightly constrained. Leakage remains below 5 μA up to 10 V per datasheet characterization curves.
Does P4KE11 meet automotive qualification standards?
Yes - the P4KE11H variant is fully AEC-Q101 qualified, having passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. The base P4KE11 (non-H suffix) is not AEC-Q101 certified, but shares identical electrical and thermal specifications. Designers targeting automotive applications must specify P4KE11H to ensure compliance with vehicle-grade reliability requirements.
What packaging options are available for P4KE11?
P4KE11 is supplied in DO-204AL (DO-41) axial-leaded package, available in two standard configurations: 5,000 units per tape-and-reel (P4KE11) and 3,000 units per ammo box (P4KE11A0G). Lead finish is pure tin, compliant with J-STD-002 for solderability, and the molding compound meets UL 94V-0 flammability rating. No surface-mount variants exist within the P4KE family.
