The 1200 V blocking voltage gives headroom for 400 VDC bus rails with derating, common in three-phase industrial PFC and high-voltage DC-DC converters. The part is RoHS compliant and lead-free per ST's standard finish.","metaTitle":"STTH812G-TR 1200 V 8 A Fast Recovery Diode, D2PAK","metaDescription":"STTH812G-TR from STMicroelectronics: 1200 V, 8 A fast recovery diode, 100 ns trr, D2PAK surface mount.

Electrical ratings (1200 V, 8 A, 100 ns trr) are identical. For automated pick-and-place, order the -TR variant; for manual assembly or low-volume prototyping, the tube-packaged STTH812G may be more convenient."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH812G-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH812G-TR when reusing this data.
