1. Introduction

The 1.5KE200A is a 1500W unidirectional TVS diode for protecting equipment from voltage transients and surges caused by lightning and inductive load switching. It has a stand-off voltage of 171V and a breakdown voltage range of 190V to 210V. This diode is commonly used in industrial power rails, telecom supplies, and solar inverters.

The 1.5KE200A belongs to the widely used 1.5KE series and is compatible across major manufacturers including Littelfuse, Vishay, ON Semiconductor, Diodes Incorporated, STMicroelectronics, Bourns, MCC, and Taiwan Semiconductor. YINT Electronics manufactures this model as a high-performance, fully compatible replacement in the DO-201 through-hole package. With a higher surge current of 5.50A compared to standard P6KE series devices, it delivers robust protection for systems needing extra surge margin.

Engineers seeking a 1.5KE200A replacement or 1.5KE200A alternative can use the YINT 1.5KE200A as a direct drop-in equivalent. It provides the same 1500W peak pulse power with a tighter breakdown tolerance for consistent clamping performance across all production lots. YINT subjects every device to 100% surge testing to guarantee compliance with published specifications for maximum designer confidence. The 1.5KE200A is an ideal choice for designers who need to upgrade from P6KE200A without changing board layout or BOM voltages.

2. Product Overview

The 1.5KE series is a popular TVS diode family covering breakdown voltages from 6.8V to 440V. Each part delivers 1500W of peak pulse power (10/1000µs waveform) in the DO-201 package. The series is widely specified for industrial and telecom surge protection applications where reliable through-hole mounting is required for mechanical robustness.

The 1.5KE200A is rated for protecting 200V DC power rails in applications that need higher surge current than the standard P6KE series. Its stand-off voltage of 171V allows normal operation on 171V to 200V DC lines without conducting under normal conditions. The device clamps transients to a maximum of 274V while handling over 5 amperes of surge current for superior transient protection. The 1.5KE200A uses a larger silicon die than the P6KE200A to achieve its higher surge rating while maintaining the same breakdown and clamping characteristics, making it an easy upgrade for designs needing more surge margin.

YINT produces the full 1.5KE series from 1.5KE6.8A through 1.5KE440A. This complete voltage range enables customers to source all DO-201 TVS diodes from one supplier, reducing qualification overhead and simplifying procurement. Advanced silicon avalanche technology and tight process controls ensure consistent performance and breakdown voltage across every production lot for reliable long-term operation.

5. Cross Reference

The 1.5KE200A is a JEDEC-registered part number used by all major TVS manufacturers. YINT's 1.5KE200A is a direct drop-in replacement with identical or tighter electrical specs. When searching for a 1.5KE200A equivalent, YINT serves as a universal cross-reference option for all major brands.

6. Comparison with Similar Models

The 1.5KE200A sits between standard P6KE and SMA/SMD options for 200V rail protection. The table below compares key parameters across similar models to help engineers choose the right part.

The 1.5KE200A offers the highest surge current (5.50A) among comparable 200V TVS diodes in a through-hole package, making it the preferred choice for high-energy surge environments. P6KE200A shares the same 1500W power rating but delivers only 2.20A Ipp, so the 1.5KE200A provides over twice the surge current capacity. For compact SMD designs, P4SMA200A and SMAJ200A provide 400W protection in small SMA packages for lower-power applications. Choose the 1.5KE200A when your application demands maximum surge current handling in a proven through-hole format with reliable mechanical mounting for demanding industrial and telecom environments. YINT offers the 1.5KE200A with 1,000 pcs/box packaging and bulk options for production orders.
