STTA106U

STTA106U Description

The STTA106U from STMicroelectronics is a high-performance 600V, 1A general-purpose diode from the TURBOSWITCH™ series, designed for fast recovery applications. Packaged in an SMB (Surface Mount) form factor with Tape & Reel (TR) delivery, this diode is optimized for efficiency in switching circuits. With a reverse recovery time (trr) of just 50ns and a forward voltage (Vf) of 1.75V @ 1A, it ensures minimal power loss and high-speed operation. Its low reverse leakage current (10µA @ 600V) enhances reliability in high-voltage environments. Though marked Obsolete, it remains a robust choice for legacy designs requiring fast recovery diodes.
