Taiwan Semiconductor Corporation P6KE13

Overview

P6KE13 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 13V nominal breakdown voltage, 10.5V stand-off voltage, 19.0V maximum clamping voltage at 33A peak surge current, and operates within -55°C to +175°C junction temperature range - deployed in automotive lighting control modules and industrial sensor interface circuits.

For engineers reviewing the P6KE13 datasheet, P6KE13 pinout, P6KE13 application, or P6KE13 equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA at 10.5V), AEC-Q101 qualification eligibility, DO-15 mechanical compatibility, and thermal derating behavior above 25°C ambient.

Technical Context

The P6KE13 uses a planar passivated silicon junction optimized for fast transient response (<1.0ps rise time from 0V to V_BR) and low dynamic impedance. Its unidirectional configuration enables asymmetric clamping with cathode-anode polarity marking, supporting DC-biased protection where reverse conduction must be blocked until breakdown threshold is exceeded.

Rated for 600W non-repetitive peak pulse power per 10/1000μs waveform, the device sustains 100A forward surge current (8.3ms half-sine) and exhibits 0.081%/°C temperature coefficient of V_BR, ensuring predictable voltage shift across automotive-grade thermal ranges.

FAQ

What is the maximum clamping voltage of P6KE13 under standard surge conditions?

The P6KE13 has a maximum clamping voltage (V_C) of 19.0 V when subjected to a 10/1000μs waveform with a peak surge current (I_PP) of 33 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream 12V ICs remain within absolute maximum ratings. The P6KE13 maintains this clamping performance across its full operating temperature range.

Is P6KE13 suitable for automotive applications requiring AEC-Q101 qualification?

The base P6KE13 is not AEC-Q101 qualified, but the P6KE13H variant - identified by the "H" suffix in the ordering code - meets AEC-Q101 stress test requirements for transient voltage suppressors. P6KE13H shares identical electrical specifications with P6KE13, including 13V nominal voltage, 10.5V V_WM, and 19.0V V_C, and is manufactured in the same DO-15 package. For automotive designs, specify P6KE13H to ensure qualification compliance without changing layout or schematic.

What is the leakage current specification for P6KE13 at its stand-off voltage?

The P6KE13 exhibits a maximum reverse leakage current (I_D) of 1 μA when biased at its rated stand-off voltage (V_WM) of 10.5 V and tested at 25°C. This ultra-low leakage ensures minimal power loss in battery-powered or energy-sensitive applications such as automotive body control modules and remote IoT sensors. Leakage remains below 5 μA even at elevated temperatures up to 125°C, as confirmed by TSC's derating curves.

How does the P6KE13 respond to fast transients like ESD or EFT?

The P6KE13 achieves a typical response time of less than 1.0 ps from 0 V to V_BR under unidirectional surge conditions, enabling effective suppression of nanosecond-scale threats including IEC 61000-4-2 ESD (±8 kV contact) and IEC 61000-4-4 EFT (5 kHz bursts). Its low dynamic impedance and planar junction structure minimize voltage overshoot during rapid dv/dt events - a key advantage over slower-acting MOVs or polymer-based protectors in sensitive analog and communication circuits using P6KE13.

What packaging options are available for P6KE13?

P6KE13 is supplied in DO-204AC (DO-15) axial package with two standard packing formats: 3,500 units per tape-and-reel (ordering code P6KE13) and 1,500 units per ammo box (ordering code P6KE13A0G). Both variants use pure tin-plated leads compliant with J-STD-002 solderability standards and meet JESD201 Class 2 whisker resistance requirements. The cathode band marking is consistent across all packages for unambiguous polarity identification during manual or automated assembly of P6KE13.
