For new designs or repairs, you will need a replacement or a surplus buy. No official successor is recorded, but a pin-compatible part from the same STTH8RxxFP family with a higher voltage rating (e.g., STTH8R06FP at 600 V) may work if the circuit allows."},{"question":"What is the reverse recovery time of STTH8R04FP?","answer":"The reverse recovery time (trr) is 50 ns, which qualifies it as a fast-recovery diode (≤500 ns, >200 mA). That 50 ns trr makes it suitable for high-frequency switching applications like PFC and SMPS output rectification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH8R04FP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH8R04FP when reusing this data.
