The common-cathode configuration means the two anodes are separate, the cathodes tied internally; verify the pinout against the original PCB layout before substituting.","metaTitle":"STMicroelectronics BYW99P-200 Fast Recovery Diode","metaDescription":"STMicroelectronics BYW99P-200 fast recovery diode: 40 ns trr, 15A per diode, 200V Vr, 850 mV Vf at 12A.","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","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"TO-218-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BYW99","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"SOT-93","Reverse Recovery Time (trr)":"40 ns","Current - Reverse Leakage @ Vr":"20 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Operating Temperature - Junction":"-40°C ~ 150°C","Voltage - Forward (Vf) (Max) @ If":"850 mV @ 12 A","Current - Average Rectified (Io) (per Diode)":"15A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/621aa4c5e4a24ddbd521b19d39cc82c7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BYW99P-200/alternatives.json"},"ai":{"faq":[{"question":"Is the BYW99P-200 obsolete?","answer":"Yes, the BYW99P-200 carries an Obsolete product status.
