STTH112A Description

Short technical summary and product information.

The STTH112A is a standard technology fast recovery rectifier diode manufactured by STMicroelectronics. It is rated for a maximum reverse voltage of 1200V and an average forward current of 1A. The forward voltage is 1.9V maximum at a forward current of 1A. The device features a reverse recovery time of 75 ns, which enables fast switching in rectifier circuits.\n\nThe diode is designed for surface mount installation and is packaged in a DO-214AC (SMA) case. It can operate at a junction temperature up to 175°C. The package is suitable for automated assembly and is compatible with standard soldering processes.\n\nTypical applications include general purpose rectification, freewheeling, and polarity protection in power supply and automotive systems.
