BAT42 Description

Short technical summary and product information.

The BAT42 is a Schottky barrier rectifier diode manufactured by STMicroelectronics. It is designed for high-speed switching applications with a maximum reverse voltage of 30V and an average rectified forward current of 200mA. The forward voltage is specified at a maximum of 1V when tested at 200mA. The device features a fast reverse recovery time of 5 ns, making it suitable for applications requiring efficient switching. The junction capacitance is typically 7pF at 1V and 1MHz.

 

The diode is packaged in a through-hole DO-35 (DO-204AH, Axial) case, which allows for easy mounting on printed circuit boards. The operating junction temperature range is -65°C to 125°C. With its small signal capability (≤200mA), this Schottky diode is ideal for low-power rectification, clamping, and protection circuits in various electronic systems.
