Its 35 ns reverse recovery time (trr) makes it suitable for freewheeling and snubber diodes in medium-frequency switching supplies, motor drives, and flyback converters where a standard recovery part would cause excessive switching loss or ringing. The DO-201AD axial package is a through-hole form factor common in legacy power supplies and industrial control boards — not a surface-mount design. ## Obsolete — plan your BOM accordingly STMicroelectronics lists the BYW98-200RL as Obsolete. No official successor order code appears in the record. For new designs, look at current fast-recovery diodes in the same voltage and current class — the 35 ns trr and DO-201AD footprint are the constraints to match. Stock the reels dry: this is a through-hole axial part, not moisture-sensitive, but store in a cool, dry environment to keep the leads solderable. ## Forward drop and leakage — the thermal budget numbers Maximum forward voltage is 1.2 V at 9 A pulsed current — that's the surge condition, not the continuous drop. At the 3 A average rating the Vf will be lower, but the 1.2 V figure gives you the worst-case conduction loss for heatsink sizing. Reverse leakage is 10 µA at 200 V, negligible at room temperature but it doubles with every 10 °C rise in junction temperature; the junction is rated to 150 °C max. If the part runs hot, budget for leakage current in the bias network.","metaTitle":"BYW98-200RL Fast Recovery Diode, 3A 200V DO-201AD, Obsolete","metaDescription":"BYW98-200RL standard fast recovery diode, 3A average rectified current, 200V reverse voltage, 35ns trr, DO-201AD axial package.","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":"Tape & Reel (TR); Cut Tape (CT)","Diode Type":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"BYW98","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-201AD","Reverse Recovery Time (trr)":"35 ns","Current - Reverse Leakage @ Vr":"10 µA @ 200 V","Voltage - DC Reverse (Vr) (Max)":"200 V","Current - Average Rectified (Io)":"3A","Operating Temperature - Junction":"150°C(Max)","Voltage - Forward (Vf) (Max) @ If":"1.2 V @ 9 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3166","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/97ab308eddcee91bcd5786beb2f626cd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reverse recovery time of BYW98-200RL?","answer":"The reverse recovery time (trr) is 35 ns, which qualifies it as a fast-recovery diode suitable for switching frequencies where standard recovery parts would cause excessive losses."},{"question":"What is the cross reference for BYW98-200RL?","answer":"No official cross-reference or second-source part number is recorded for the BYW98-200RL.
