STTH312B-TR Description

Short technical summary and product information.

The STMicroelectronics STTH312B-TR is an ultrafast recovery rectifier diode designed for demanding applications requiring high reliability. It features a 1200V repetitive peak reverse voltage and an average forward current of 3A. The diode offers very low conduction and switching losses, making it suitable for high frequency and pulsed current operation.

 

Key electrical characteristics include a maximum forward voltage of 2V at 3A and a typical reverse leakage current of 10µA at 1200V. The ultrafast, soft recovery is characterized by a typical reverse recovery time (trr) of 55ns under specific test conditions. The maximum operating junction temperature is 175°C.

 

This diode is housed in a TO-252-3, DPAK (2 Leads + Tab), SC-63 surface mount package, ideal for space-constrained designs. Its robust construction and performance characteristics make it suitable for industrial power supplies, motor control, and auxiliary functions like snubbers and demagnetization circuits.
