STTH806DTI

STTH806DTI Description

The STTH806DTI from STMicroelectronics is a high-performance 600V, 8A general-purpose diode designed for demanding power electronics applications. Packaged in a TO-220AC through-hole mount, this diode combines fast recovery (<500ns) with low reverse leakage (10µA @ 600V), making it ideal for high-efficiency rectification and switching circuits. Its 30ns reverse recovery time (trr) ensures minimal switching losses, while the 175°C maximum junction temperature allows reliable operation in harsh environments. Compliant with ROHS3 and REACH standards, it is suitable for industrial, automotive, and consumer applications requiring robust performance.
