The 200 V reverse voltage rating and 20 µA leakage at 200 V suit it for 48 V telecom rails and 110 Vdc intermediate buses, with margin for transients. The BYW99PI-200RG is officially obsolete per STMicroelectronics. For new designs, a pin-compatible alternative in the same TOP-3I package should be evaluated. No last-time-buy window remains — the surplus channel is the only supply path. The TOP-3I insulated package eliminates the need for an isolation pad between the diode tab and the heatsink, which simplifies assembly and improves thermal transfer. The through-hole mounting suits point-of-load rectifier stages on single-sided or mixed-technology boards where reflow isn't an option for the power devices.","metaTitle":"STMicroelectronics BYW99PI-200RG Fast Recovery Diode","metaDescription":"BYW99PI-200RG fast recovery diode from STMicroelectronics, 15 A per diode, 200 V, 40 ns trr, TOP-3I.","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":"TOP-3 Insulated","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BYW99","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"TOP-3I","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/BYW99PI-200RG/alternatives.json"},"ai":{"faq":[{"question":"What is the trr of BYW99PI-200RG?","answer":"The reverse recovery time (trr) is 40 ns, which qualifies it as a fast recovery diode for switching frequencies up to around 100 kHz."},{"question":"Is BYW99PI-200RG equivalent to STTH2002PI?","answer":"The STTH2002PI is a common cross-shop candidate in the same TOP-3I package, but it is not an official equivalent.
