STTH512D Description

Short technical summary and product information.

The STTH512D is a general purpose fast recovery diode manufactured by STMicroelectronics. It is designed for applications requiring high voltage and fast switching performance. The diode features a repetitive peak reverse voltage of 1.2kV and an average rectified current rating of 5A, making it suitable for power supply and motor control circuits.

 

The device offers a fast reverse recovery time of 95ns, which minimizes switching losses in high-frequency applications. The forward voltage drop is maximum 2.2V at 5A forward current. The diode is built with standard technology and can operate at junction temperatures up to 175°C.

 

The STTH512D is housed in a through-hole TO-220-2 package, also known as TO-220AC, which provides excellent thermal performance and ease of mounting. The package is suitable for automated assembly and offers reliable heat dissipation.

 

The component is RoHS compliant and has a moisture sensitivity level of 1 (unlimited), ensuring robust handling during manufacturing.
