Dual fast-recovery rectifier in a single TO-277A package
The STTH602CSFY from STMicroelectronics is a 200 V, 3 A per diode fast-recovery rectifier in a common-cathode pair, housed in the SMPC surface-mount package. It is qualified to AEC-Q101 and built on the ECOPACK2 platform, making it RoHS-compliant and ready for automotive production lines.
The 31 ns reverse recovery time (trr) at 200 V reverse places this diode in the fast-recovery class. The 1.06 V forward drop at 3 A is a typical ultrafast figure.
175°C junction — under-hood margin
The 4 µA reverse leakage at 200 V is specified at 25°C; expect leakage to rise with temperature, but the 175°C Tj ceiling gives the thermal designer headroom for a compact heatsink.
For automotive programs that require multi-year supply assurance, this part is currently in standard production and can be quoted against BOM quantities through independent distribution.
