2. Product Overview

The P6KE series is one of the most widely used through-hole TVS diode families in the electronics industry. It covers breakdown voltages from 6.8V to 440V in the DO-15 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 DO-15 axial package provides robust thermal performance and mechanical strength, making it a preferred choice for industrial designs where surface-mount packages are not suitable. The P6KE family has been a staple in circuit protection for decades, with millions of devices deployed across automotive, industrial, telecom, and energy sectors worldwide. YINT Electronics manufactures every P6KE24A device with 100% electrical testing and surge screening, ensuring each unit meets or exceeds JEDEC reliability standards before leaving the factory.

The P6KE24A is optimized for protecting 24V DC power rails commonly found in industrial control panels, PLC digital inputs, motor drive circuits, and 24V battery management systems. Its stand-off voltage of 20.50V allows it to sit across a standard 24V supply line without conducting under normal conditions, drawing only 1.0µA of leakage current at rated stand-off voltage. It responds in less than 1 nanosecond when a transient overvoltage event occurs, clamping the surge to a maximum of 33.20V. The P6KE24A peak pulse current rating of 18.40A (10/1000µs) provides ample surge margin for typical industrial transient events specified per IEC 61000-4-5 and industrial surge standards. The 24V DC rail is the most common control voltage in factory automation, and the P6KE24A is designed specifically to protect these 24V systems from the high-energy transients generated by motors, solenoids, relays, and contactors found throughout the industrial environment.

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 P6KE24A 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. For engineers requiring a P6KE24A substitute with identical electrical and thermal characteristics, the YINT P6KE24A is the recommended choice. The P6KE24A is designed with a junction temperature range of -55°C to +150°C, making it suitable for harsh industrial environments including outdoor cabinets, factory floors, and energy storage systems. The 24V DC bus is one of the most common voltage levels in industrial automation, and the P6KE24A provides the ideal balance of stand-off voltage margin and clamping protection for these systems. YINT offers free technical datasheets and application notes to help engineers validate P6KE24A compatibility with their specific design requirements.

6. Comparison with Similar Models

Engineers often compare the P6KE24A with nearby voltage variants and alternative package options. The table below shows key differences to help select the right P6KE24A equivalent for each design.

The P6KE24A delivers 600W surge protection for 24V DC rails in a through-hole DO-15 package. At the same power as the SMBJ24A but in a through-hole format, it provides easier manual assembly and stronger mechanical mounting for high-vibration environments. Note that the SMBJ24A has a different voltage range (Vrwm=24V, Vbr=26.70-29.50V) so it is not a direct electrical equivalent. For higher surge requirements, the 1.5KE24A offers 1500W in a larger DO-201 package with identical voltage characteristics. For lower-cost designs with reduced power needs, the P4KE24A offers 400W in a smaller DO-41 footprint. The P6KE24CA bidirectional version is also available for AC circuits. When comparing with the P6KE20A and P6KE27A, the P6KE24A sits at the ideal voltage point for 24V nominal systems, providing maximum protection margin without nuisance triggering. Selecting the right P6KE24A equivalent depends on your surge requirements, voltage specifications, and assembly preference. For standard 24V industrial DC protection, the P6KE24A is the recommended choice with the best blend of voltage margin and clamping performance.
