It uses FERD technology, which combines a low forward voltage drop — 705 mV at the full 20 A rated current — with reverse leakage that stays tighter than a conventional Schottky at elevated junction temperatures. At 20 A the forward voltage sits at 705 mV. The fast recovery classification (≤ 500 ns, > 200 mA) covers line-frequency rectification and moderate-speed switching. ## Package and mounting — TO-220 fit Through-hole TO-220-3. The tab is the cathode. Heatsink clip or screw mount — standard TO-220 hole pattern. ROHS3 compliant. No NRND or EOL notice. The part ships in tube. For BOM planning: this is a current ST part, not a phase-out.","metaTitle":"ST FERD20H100STS FERD Diode, 100V 20A TO-220, Active","metaDescription":"FERD20H100STS is a 100 V, 20 A Field Effect Rectifier Diode in TO-220.

No exemption-dated substances above the threshold."},{"question":"What is the difference between FERD and Schottky?","answer":"FERD (Field Effect Rectifier Diode) uses a MOS-controlled channel to achieve a forward drop similar to a Schottky but with lower reverse leakage at high temperature and softer recovery. The trade-off is slightly higher turn-off charge than a Schottky, which matters above 100 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/FERD20H100STS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/FERD20H100STS when reusing this data.
