Obsolete — sourcing strategy for the STTH8BC065DI
Any procurement for this order code will go through the independent distribution channel — surplus stock, new-old-stock, or verified broker inventory. The buyer should qualify an alternative part for new designs or plan for a one-time buy of remaining available stock for legacy BOM lines.
650 V, 8 A, 25 ns trr — what these ratings mean for the power stage
The STTH8BC065DI is a standard fast-recovery epitaxial diode rated for 650 V DC reverse voltage and 8 A average rectified current. The 25 ns reverse recovery time (trr) places it in the fast-recovery class, suitable for continuous-conduction-mode boost stages, PFC front ends, and output rectification in switching power supplies where reverse-recovery losses directly affect efficiency and thermal stress. The 650 V rating provides margin for 400 V DC bus rails and universal-input PFC stages, though the designer should verify derating against the peak repetitive voltage in the specific topology.
TO-220AC insulated package — mounting and thermal considerations
The STTH8BC065DI is supplied in a TO-220AC insulated package (TO-220-2 Insulated, supplier device package TO-220AC ins). The through-hole mounting suits point-of-load heatsinking on a main PCB or a separate heatsink bracket.
