Its 20 ns reverse recovery time (trr) keeps switching losses low in the 50–100 kHz range, which is where this class of diode earns its keep — think PFC boost stages, output rectification in flyback converters, and clamp snubbers where a standard recovery part would run hot. ## 4 A per diode — thermal budget in the full-pack The TO-220FP case has higher thermal resistance than a standard TO-220 metal tab, so the junction temperature hitting 175°C maximum is the real constraint. STMicroelectronics lists the STTH802CFP as obsolete. There is no official successor code in the record. For a production BOM that calls out this exact diode, the path is independent distribution — surplus and new-old-stock inventory sourced through broker and specialty channels. The common-cathode TO-220FP footprint is shared across several STTH family parts, so a pin-compatible substitute may exist within the same voltage/current tier, but no cross-reference is documented here. Qualification of any alternate belongs on the design team's bench.","metaTitle":"STTH802CFP Fast Recovery Diode, 200V 4A, TO-220FP, 20ns trr","metaDescription":"STTH802CFP 200V 4A fast recovery diode in TO-220FP. 20 ns trr, common-cathode pair.
