Product details
Overview
P6KE11CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 11 V, clamps transients to ≤16.2 V at 38 A peak surge current, and delivers sub-1 ps response time from 0 V to VBR. It is AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for automotive-grade ESD and lightning surge protection.
For engineers reviewing the P6KE11CH datasheet, P6KE11CH pinout, P6KE11CH application, or P6KE11CH equivalent, this page provides verified electrical parameters, mechanical packaging details, real-world use cases in automotive and industrial systems, and validated alternative parts with documented functional differences.
Technical Context
The P6KE11CH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage of 9.9 V (tested at 1 mA). Its low dynamic impedance ensures effective clamping during fast transients such as ISO 7637-2 pulse 1/2a/5a and IEC 61000-4-5 surge events.
It supports steady-state power dissipation of 5 W at 75 °C with lead lengths of 9.5 mm, and its junction temperature range spans –55 °C to +175 °C - enabling deployment in under-hood automotive environments and industrial motor drives where thermal stress is significant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.9 V / 12.1 V at 1 mA - defines reliable turn-on threshold across temperature and unit variation |
| VWM | 8.92 V - maximum continuous reverse working voltage before leakage rises above 1 μA |
| VC @ IPP | 16.2 V at 38 A (10/1000 μs) - clamping voltage limiting downstream IC stress during surge events |
| PPK | 600 W - peak non-repetitive surge power handling capability per standard waveform |
| IR @ VWM | <1 μA - ultra-low leakage preserving battery-backed or high-impedance sensor node integrity |
| TJ max | +175 °C - enables operation in high-ambient environments without derating concerns |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package compatible with automated through-hole assembly |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, epoxy-molded, cathode indicated by band. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional configuration |
| Cathode (banded end) | Reverse-biased clamping terminal | Connected to protected line (e.g., 12 V rail); conducts only during overvoltage to shunt energy to ground |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring reliability under thermal cycling and vibration |
| 600 W surge rating (10/1000 μs) | Withstands repetitive load dump and inductive switching surges common in 12 V vehicle electrical systems |
| Clamping voltage ≤16.2 V | Protects 12 V-rated ICs (e.g., CAN transceivers, microcontrollers) without exceeding absolute maximum ratings |
| Response time <1 ps | Engages before most semiconductor junctions experience avalanche failure during ESD or fast transients |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and UL 94V-0 flammability standards for environmentally regulated industrial and automotive production |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|

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 SMAJ11A | Same DO-214AC (SMA) package; 11 V nominal, 18.2 V clamping at 32.4 A; 400 W rating | Lower surge rating and higher clamping voltage reduce margin for severe load dump events | Select when space-constrained SMT layout is required and 400 W surge capacity suffices |
| ON Semiconductor 1.5KE11A | Same DO-204AC (DO-15) package; 11 V nominal, 17.5 V clamping at 36 A; 1500 W rating (10/1000 μs) | Higher surge rating but larger 1.5 kW package requires more board area and thermal management | Select when legacy 1.5KE footprint compatibility is mandatory and higher surge margin justifies larger size |
Compared with P6KE11CH, SMAJ11A trades surge robustness for surface-mount compatibility, while 1.5KE11A offers greater power handling in the same axial form factor but with increased thermal mass and cost - making P6KE11CH optimal for cost-sensitive, AEC-Q101-compliant 600 W protection in compact through-hole designs.

FAQ
What is the clamping voltage of P6KE11CH at its rated surge current?
The P6KE11CH clamps to a maximum of 16.2 V at 38 A peak pulse current (10/1000 μs waveform), as specified in the Electrical Specifications table. This value ensures protected circuits remain within safe operating limits during standardized surge events, and is measured under controlled test conditions per ANSI/IEEE C62.35.
Is P6KE11CH suitable for bidirectional transient protection?
No, P6KE11CH is a unidirectional TVS diode - its cathode band indicates polarity, and it conducts only in reverse bias. For bidirectional protection, select P6KE11CA (with "CA" suffix), which provides symmetrical clamping in both directions and is explicitly designated for bipolar applications in the datasheet.
Does P6KE11CH meet automotive qualification standards?
Yes, P6KE11CH is AEC-Q101 qualified, as confirmed in the FEATURES section and ORDERING INFORMATION (the "H" suffix denotes AEC-Q101 compliance). It is rated for junction temperatures from –55 °C to +175 °C and validated for reliability under automotive stress conditions including thermal cycling and mechanical vibration.
What is the maximum steady-state power dissipation for P6KE11CH?
P6KE11CH has a steady-state power dissipation (PD) of 5 W at TA = 75 °C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This rating applies to continuous DC or low-frequency reverse-bias conditions - not transient surge events, where the 600 W peak rating governs.
How does the leakage current of P6KE11CH compare to other 11 V TVS diodes?
P6KE11CH specifies maximum reverse leakage current (IR) of <1 μA at its 8.92 V stand-off voltage (VWM), measured at 25 °C. This ultra-low leakage is critical for battery-powered or high-impedance circuits, and matches or exceeds performance of comparable 11 V TVS devices like SMAJ11A (≤1 μA) and 1.5KE11A (≤5 μA).
