Dual fast-recovery diode in a compact TO-277A footprint
The STTH602CSF from STMicroelectronics is a 200 V, 3 A per-diode fast-recovery rectifier pair in a common-cathode configuration, housed in the TO-277A (SMPC) surface-mount package. It is part of the ECOPACK®2 series, meeting RoHS and halogen-free requirements. The 31 ns reverse recovery time (trr) makes it suited for high-frequency switching applications such as power-factor correction (PFC) boost stages, flyback snubbers, and output rectification in offline converters.
31 ns trr — what it means for switching loss
The STTH602CSF has a trr of 31 ns at 200 V. This reduces turn-off losses in hard-switched topologies.
3 A per diode, 1.06 Vf — thermal budget
Each diode in the pair is rated for 3 A average rectified current (Io) with a forward voltage of 1.06 V maximum at that current. The 175°C Tj rating provides headroom for high-ambient environments like enclosed power supplies or under-hood automotive modules.
STMicroelectronics lists the STTH602CSF as Active. The ECOPACK®2 designation confirms compliance with RoHS and halogen-free directives, so it fits lead-free assembly flows without exemption paperwork.
