Its 65 ns reverse recovery time (trr) is the headline switching parameter — fast enough to keep turn-off losses low in continuous-conduction-mode PFC boost stages and output rectification in hard-switched converters up to the 100 kHz range, without the higher Vf penalty of an ultrafast or SiC diode. ## Ratings that set the operating envelope Averaged rectified current of 30 A and a 600 V reverse voltage ceiling define the continuous-load boundary. Reverse leakage is specified at 10 µA at 600 V — a clean blocking characteristic that keeps standby dissipation negligible in offline supplies.","metaTitle":"STTH31AC06SPF Fast Recovery Diode, 600V 30A TO-3PF, 65ns trr","metaDescription":"STTH31AC06SPF general-purpose fast recovery diode, 600V 30A, 65ns trr, TO-3P-3 Full Pack.

The slower trr means higher turn-off losses — check the switching loss budget before substituting. Pin-compatibility should be verified against the specific package drawing, as the lead form can differ between the two base numbers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH31AC06SPF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH31AC06SPF when reusing this data.
