It has a stand-off voltage of 25.6V and a breakdown voltage range of 28.5V to 31.5V. This diode works in industrial controls, telecom equipment, power supplies, and building automation systems.

The P6KE30A is a JEDEC-registered industry standard number compatible across all major TVS manufacturers including Littelfuse, Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, Bourns, and Taiwan Semiconductor. YINT Electronics manufactures this model as a fully compatible replacement in the DO-15 through-hole package. The device responds in less than 1 nanosecond and delivers 600W peak pulse power (10/1000µs waveform). YINT's manufacturing process includes 100% surge testing and electrical characterization on every device for guaranteed performance.

Engineers looking for a P6KE30A replacement or P6KE30A alternative can specify the YINT P6KE30A as a direct drop-in equivalent. It offers tight breakdown tolerance and low reverse leakage for consistent, reliable performance across every production lot. The 1.0µA maximum leakage current minimizes power loss in sensitive applications. YINT's manufacturing process includes 100% surge testing on every device to guarantee compliance with published specifications, giving designers full confidence in their protection circuit design.

2. Product Overview

The P6KE series is one of the most widely used TVS diode families in electronics. It covers breakdown voltages from 6.8V to 440V in the DO-15 through-hole package. Each part delivers 600W of peak pulse power dissipation for a broad range of surge protection applications from low-voltage logic to high-voltage power systems.

The P6KE30A is a 600W rated variant for protecting 24V DC power rails in industrial and telecom equipment. Its stand-off voltage of 25.6V lets it sit across a 24V supply line without conducting under normal conditions. It responds in less than 1 nanosecond when a transient overvoltage event occurs, clamping the surge to a maximum of 41.4V.

YINT produces the full P6KE series from P6KE6.8A through P6KE440A. This complete voltage coverage lets customers source all DO-15 TVS needs from one manufacturing partner, simplifying supply chain management and reducing qualification costs. The P6KE30A uses advanced silicon avalanche technology with tight process controls for consistent breakdown voltage and surge current capability across every production lot. YINT's 19+ years of experience in circuit protection manufacturing means every device benefits from mature, proven production processes that deliver reliable long-term performance.
