Product details
Overview
P6KE10 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 10 V, clamps transients to ≤15.0 V at 10 A peak surge current, and delivers low dynamic impedance with <1 μA reverse leakage at 8.10 V standoff voltage. It is used in automotive body electronics, industrial sensor interfaces, and AC/DC adapter input stages.
For engineers reviewing the P6KE10 datasheet, P6KE10 pinout, P6KE10 application, or P6KE10 equivalent, this page provides verified electrical parameters, DO-204AC package details, clamping performance under 10/1000 µs surges, thermal derating behavior, and AEC-Q101-qualified alternatives for automotive-grade designs.
Technical Context
The P6KE10 operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 9.00–11.00 V breakdown range at 1 mA test current. Its junction capacitance is not specified in the provided documentation, and it exhibits a temperature coefficient of VBR of 0.073 %/°C.
It is rated for non-repetitive 600 W peak pulse power per 10/1000 µs waveform, with steady-state power dissipation limited to 5 W at 75 °C ambient on 5 × 5 mm copper pads. Maximum junction temperature is 175 °C, and storage temperature spans –55 to +175 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ10A | Same DO-214AC package; 10 V standoff, 15.4 V clamping at 10.3 A; slightly higher leakage (5 µA @ 8.1 V) | Preferred for space-constrained PCBs where surface-mount is required instead of axial DO-15 | Select when board layout mandates SMD footprint and thermal pad access is available |
| Taiwan Semiconductor P6KE10H | Identical electrical specs; AEC-Q101 qualified; same DO-204AC package; marked with "H" suffix | Mandatory for automotive OEM production; supports extended temperature validation and traceable lot control | Choose for Tier-1 automotive programs requiring PPAP documentation and qualification evidence |
Compared with P6KE10, SMAJ10A offers SMD compatibility at the cost of higher leakage and different thermal mounting, while P6KE10H adds automotive qualification without altering electrical behavior-making it the drop-in upgrade for automotive deployments.

FAQ
What is the clamping voltage of P6KE10 at its rated peak surge current?
The P6KE10 clamps to a maximum of 15.0 V when subjected to its rated peak surge current of 10 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and reflects worst-case voltage seen by downstream circuitry during surge events. The P6KE10 maintains this clamping performance across its operational temperature range up to 175 °C junction temperature.
Is P6KE10 unidirectional or bidirectional, and how is polarity identified?
P6KE10 is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. Polarity is identified by a cathode band marked on the DO-204AC (DO-15) package - the banded end is the cathode and must be connected toward the higher-potential side of the protected line. Bidirectional variants in the same series carry "CA" or "C" suffixes (e.g., P6KE10CA), which P6KE10 does not.
Does P6KE10 meet automotive qualification standards?
The base P6KE10 is not AEC-Q101 qualified; however, its variant P6KE10H is fully AEC-Q101 qualified and shares identical electrical specifications and DO-204AC packaging. P6KE10H undergoes additional stress testing including temperature cycling, humidity bias HAST, and mechanical shock per AEC-Q101 Rev D, making it suitable for automotive body electronics and lighting modules.
What is the maximum steady-state power dissipation for P6KE10 at elevated ambient temperatures?
P6KE10 has a steady-state power dissipation rating of 5 W at 75 °C ambient temperature when mounted on 5 × 5 mm copper pads per lead. Above 75 °C, power rating must be linearly derated per the published pulse derating curve (Fig.2), reaching zero at 175 °C junction temperature. This derating applies to continuous DC power, not transient surge conditions.
Can P6KE10 be used in bidirectional signal line protection?
No - P6KE10 is strictly unidirectional and unsuitable for bidirectional signal lines such as RS-485 or CAN without external circuitry. For bidirectional protection, engineers must select the CA-suffixed variant (e.g., P6KE10CA) or pair two unidirectional devices in series opposition. Using P6KE10 alone on a bidirectional line risks forward conduction during normal signal swings and fails to suppress positive-going transients on the anode side.
