STTH8R04DI Description

Short technical summary and product information.

The STTH8R04DI is a fast recovery rectifier diode from STMicroelectronics, designed for high-efficiency switching applications. It is rated for a maximum reverse voltage of 400V and an average rectified current of 8A, with a maximum forward voltage of 1.5V at 8A. The device features a fast recovery time of 50ns, suitable for high-frequency circuits.

 

The diode utilizes standard technology and operates over a junction temperature range of -40°C to 175°C. It is supplied in a TO-220AC insulated package, providing electrical isolation and ease of mounting. The through-hole mounting type allows for robust mechanical attachment in power supply and inverter designs.

 

Typical applications include freewheeling diodes, snubber circuits, and output rectification in switched-mode power supplies (SMPS) and motor control systems. The fast recovery characteristic minimizes switching losses and improves efficiency.
