The 30 ns trr keeps the recovery spike short enough that a standard RC snubber can control the overshoot without excessive dissipation. AEC-Q101 qualification and a 175°C maximum junction temperature make this part suited for under-hood automotive DC-DC stages and high-ambient industrial power supplies.
Common-cathode pair in DPAK — board-area trade-off
Two diodes share the same cathode in a single DPAK (TO-252) package. This configuration directly replaces two discrete fast-recovery diodes in center-tapped rectifiers or half-bridge topologies, cutting component count and PCB footprint. The exposed tab is the common cathode — the thermal pad connects to this node, so the copper pour on the cathode net doubles as a heatsink. The 175°C junction rating provides margin for the thermal coupling between the two dice; derate the total dissipation against the package's thermal resistance when both diodes conduct simultaneously.
STMicroelectronics lists the STTH602CBY-TR as Active. For automotive OEMs requiring a documented second source, the common-cathode fast-recovery diode market has several parametric equivalents, but no direct pin-compatible alternate is named in the official cross-reference. Qualification to AEC-Q101 is already in place, so requalification effort for a substitute would fall on the buyer.
