1. Introduction

The P6KE6.8A is a 600W unidirectional TVS diode designed for 5V and 6.8V DC rail protection. It clamps transients from ESD, lightning, and inductive load switching in low-voltage electronics, microcontrollers, and communication interfaces. With a stand-off voltage of 5.80V and a breakdown range of 6.45V to 7.14V, this device is optimized for protecting 5V and 3.3V logic circuits.

The P6KE6.8A is a JEDEC-registered industry standard number in the DO-15 (DO-204AC) through-hole package, cross-compatible with Littelfuse, Vishay, ON Semiconductor, Diodes Inc, STMicroelectronics, and Bourns. YINT Electronics manufactures it as a fully compatible drop-in replacement. The device responds in less than 1 nanosecond and delivers 600W peak pulse power (10/1000µs waveform). YINT's manufacturing includes 100% surge testing on every device.

Engineers searching for a P6KE6.8A replacement or P6KE6.8A alternative can specify the YINT P6KE6.8A as a direct drop-in equivalent. It offers tight breakdown tolerance for consistent clamping performance across every production lot.

2. Product Overview

The P6KE series covers breakdown voltages from 6.8V to 440V in the DO-15 package. Each device delivers 600W peak pulse power. The P6KE6.8A is the lowest-voltage variant, protecting sensitive 5V and 3.3V DC rails in embedded systems, IoT devices, and industrial control modules.

The P6KE6.8A has a stand-off voltage of 5.80V, letting it sit across a 5V supply line without conducting under normal conditions. When a transient overvoltage event occurs, it responds in less than 1 nanosecond and clamps the surge to a maximum of 10.50V, safely protecting downstream components. The device handles 58.10A peak pulse current (10/1000µs waveform), covering ESD strikes, cable discharge events, and inductive load switching transients.

YINT produces the full P6KE series from 6.8V through 440V. This broad voltage range lets design teams source all axial-lead TVS needs from one manufacturing partner, simplifying qualification and supply chain. The P6KE6.8A uses advanced silicon avalanche technology with tight process controls for consistent breakdown voltage across every production lot.
