Its 4 ns reverse recovery time (trr) suits it for high-speed switching applications such as logic-level clamping, flyback suppression, and signal rectification in control circuits. ## Parametric performance under temperature Reverse leakage is specified at 25 nA maximum at 20 V reverse bias, confirming a clean junction at room temperature. At the high end, leakage current rises with temperature per the standard silicon diode characteristic, so the 25 nA figure at 25°C may increase by an order of magnitude at 125°C junction. ## Through-hole DO-35 package for point-to-point wiring The glass-sealed body provides hermeticity against moisture ingress, a consideration for long-life industrial or aerospace assemblies.","metaTitle":"Microchip 1N4448 Small-Signal Diode, 200mA, 75V, DO-35","metaDescription":"Microchip Technology 1N4448 small-signal switching diode, 200 mA average rectified current, 75 V reverse voltage, 4 ns trr, DO-35 axial package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Microchip Technology","Speed":"Small Signal =< 200mA (Io), Any Speed","Series":"-","Package":"Bulk","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-204AH, DO-35, Axial","lifecycle_stage":"eol_hot","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-35","Reverse Recovery Time (trr)":"4 ns","Current - Reverse Leakage @ Vr":"25 nA @ 20 V","Voltage - DC Reverse (Vr) (Max)":"75 V","Current - Average Rectified (Io)":"200mA","Operating Temperature - Junction":"-65°C ~ 150°C","Voltage - Forward (Vf) (Max) @ If":"1 V @ 100 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5bcd0681004dba2d8134c1d33a613d5a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1N4448/alternatives.json"},"ai":{"faq":[{"question":"How can I get current pricing and availability for 1N4448?","answer":"Pricing and stock levels are confirmed at quote time.
