BYW29G-200-TR

BYW29G-200-TR Description

The BYW29G-200-TR is a 200V, 8A general-purpose fast recovery diode from STMicroelectronics, designed for high-efficiency rectification in power electronics. Packaged in a D2PAK (TO-263) surface-mount form factor, it is optimized for fast switching with a reverse recovery time (trr) of 35 ns, making it ideal for high-frequency applications. The diode features a low forward voltage drop (1.15V @ 10A) and minimal reverse leakage (10 µA @ 200V), ensuring energy efficiency and thermal stability. Although marked as obsolete, it remains a reliable choice for legacy designs requiring robust performance in demanding environments.
