It is designed for high-frequency DC-DC converter secondary-side rectification, freewheeling diodes in switching supplies, and reverse polarity protection circuits where low forward voltage drop and fast switching are needed. At 1 A forward current the STPS1H100MF drops 770 mV typical. That figure drives the conduction loss and junction temperature rise in the application. For a 1 A load the dissipation is about 770 mW — manageable in the STmite Flat package if the PCB copper area is adequate. If your design runs at 0.5 A or below the drop will be lower, improving efficiency further. Compare this to a standard PN-junction rectifier that might drop 1.1 V at the same current — the Schottky saves roughly 330 mW per amp, which adds up in a multi-output supply. ## Package and rework: STmite Flat The DO-222AA STmite Flat is a small, low-profile surface-mount package. It is rework-friendly under a hot-air station if you have a fine nozzle and steady hands — the body is small, so alignment matters. Pin 1 orientation is marked on the package body. The flat leads have good solder wetting; just keep the hot-air temperature under 350°C and preheat the board to avoid thermal shock. The package is MSL 1 per typical ST Schottky handling, so no bake required before reflow if the bag seal is intact. That means no last-time-buy clock is running, and the part is in normal production through ST's distribution channel. For a BOM line this translates to predictable supply and no forced redesign.","metaTitle":"STPS1H100MF Schottky Diode, 100V 1A, DO-222AA STmite Flat","metaDescription":"STPS1H100MF Schottky rectifier: 100 V reverse, 1 A average, 770 mV forward drop at 1 A, 175°C Tj max, DO-222AA STmite Flat package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Technology":"Schottky","Mounting Type":"Surface Mount","Package / Case":"DO-222AA","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"STPS1","Capacitance @ Vr, F":"-","Supplier Device Package":"STmite Flat","Current - Reverse Leakage @ Vr":"4 µA @ 100 V","Voltage - DC Reverse (Vr) (Max)":"100 V","Current - Average Rectified (Io)":"1A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"770 mV @ 1 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7652dfbd973e5e175623f0ff21f1a2d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS1H100MF/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS1H100MF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS1H100MF when reusing this data.
