The 50 ns reverse recovery time places it in the fast-recovery class, suitable for switching power supplies, freewheeling diodes in motor drives, and snubber circuits where recovery losses matter. This part is listed as obsolete by the manufacturer. ## Common-cathode pair in a TO-218 — board-level fit The two diodes share a common cathode on pin 2 (tab), with the anodes on pins 1 and 3. This layout is standard for center-tapped rectifier stages and dual-switch clamp networks. The TO-218-3 (SOT-93) through-hole package is a larger plastic power package — expect a 10.2 mm body width and a mounting hole for a screw or clip to a heatsink.","metaTitle":"BYV52-200 Fast Recovery Diode, 50 ns trr, 30 A, TO-218","metaDescription":"BYV52-200 fast recovery diode pair, 50 ns trr, 30 A per diode, 200 V, common cathode, TO-218-3 (SOT-93).","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-218-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BYV52","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"SOT-93","Reverse Recovery Time (trr)":"50 ns","Current - Reverse Leakage @ Vr":"25 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"-40°C~150°C","Voltage - Forward (Vf) (Max) @ If":"850 mV @ 20 A","Current - Average Rectified (Io) (per Diode)":"30A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/622ca51c509158a343bba5e339092841.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BYV52-200/alternatives.json"},"ai":{"faq":[{"question":"Is BYV52-200 obsolete or still available?","answer":"Yes, BYV52-200 is listed as obsolete.
