Taiwan Semiconductor Corporation P6KE62H

Overview

P6KE62H 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 62 V, clamps transients to ≤89.0 V at 7.0 A peak surge current, and delivers sub-nanosecond response time (<1.0 ps from 0 V to V_BR) - critical for safeguarding automotive ECUs against ISO 7637-2 pulse 1/2a/5a.

For engineers reviewing the P6KE62H datasheet, P6KE62H pinout, P6KE62H application, or P6KE62H equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility with high-reliability board layouts, 50.2 V stand-off voltage margin, and 0.104 %/°C V_BR temperature coefficient for stable clamping across -55°C to +175°C junction range.

Technical Context

The P6KE62H operates as a silicon avalanche diode with single-die construction in a DO-204AC case. Its clamping action relies on controlled reverse-biased avalanche breakdown, triggered within <1.0 ps when transient voltage exceeds 55.8 V (V_{BR min}) at 1 mA test current. The device sustains 600 W non-repetitive peak pulse power under 10/1000 µs waveform per IEC 61000-4-5.

Thermal performance is defined by a 175 °C maximum junction temperature and derating above 25 °C ambient per Fig.2. With 1 μA max reverse leakage at 50.2 V (V_WM) and 0.400 g mass, it supports compact PCB placement while meeting UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

FAQ

What is the maximum clamping voltage of the P6KE62H under standard surge conditions?

The P6KE62H has a maximum clamping voltage (V_C) of 89.0 V when subjected to a 10/1000 µs waveform at 7.0 A peak pulse current (I_PP). This value is measured per IEC 61000-4-5 and ANSI/IEEE C62.35 standards and ensures downstream components rated for ≤100 V remain within safe operating limits during transient events. The P6KE62H maintains this clamping performance across its full operating temperature range.

Is the P6KE62H suitable for automotive applications?

Yes, the P6KE62H is AEC-Q101 qualified - explicitly confirmed in the ordering information note stating "H" suffix denotes AEC-Q101 qualification (excluding P6KE6V8A–P6KE9V1A). It meets stress test requirements including high-temperature operating life, temperature cycling, and unbiased HAST, making it suitable for engine control units, body electronics, and lighting modules in passenger and commercial vehicles.

What is the stand-off voltage (V_WM) of the P6KE62H and why does it matter?

The P6KE62H has a maximum stand-off voltage (V_WM) of 50.2 V, meaning it remains in high-impedance blocking mode up to this DC or RMS voltage level with leakage <1 μA. This 50.2 V rating provides a 11.8 V margin below the nominal 62 V breakdown, ensuring reliable non-conduction during normal 48 V or 50 V system operation while allowing headroom for ripple and tolerance. Exceeding V_WM risks excessive leakage or premature clamping.

How does the P6KE62H compare to the P6KE62A variant?

The P6KE62H and P6KE62A share identical electrical specifications - both have V_BR = 55.8–68.2 V, V_WM = 50.2 V, V_C = 89.0 V, and 600 W rating - but differ in qualification status. The "H" suffix indicates AEC-Q101 qualification, whereas "A" denotes tighter V_BR tolerance (58.9–65.1 V vs. 55.8–68.2 V) without automotive qualification. Thus, P6KE62H is selected when automotive reliability validation is mandatory, not just tighter voltage binning.

What package type and lead finish does the P6KE62H use?

The P6KE62H uses the DO-204AC (DO-15) axial-leaded package with pure tin-plated leads compliant with J-STD-002 for solderability. The molding compound meets UL 94V-0 flammability rating, and the device passes JESD201 Class 2 whisker testing. Its approximate weight is 0.400 g, and polarity is marked by a cathode band - essential for correct unidirectional installation in power rail protection circuits.
