This diode is built for high-voltage, fast-switching applications such as boost diodes in power-factor-correction stages, freewheeling diodes in flyback converters, and snubber clamping in motor drives. A 75 ns reverse recovery time places this diode in the fast-recovery class, suitable for switching frequencies in the tens of kilohertz. In a continuous-conduction-mode PFC boost stage, the 75 ns trr limits the reverse-recovery charge that the MOSFET must absorb, reducing turn-on loss and ringing. The 1.75 V forward drop at 2 A is a trade-off for the speed — expect higher conduction loss than a slower 1200 V standard-recovery diode, but lower switching loss overall. STMicroelectronics lists the STTH212RL as Obsolete. The base product number STTH21 family may include active variants, but this specific RL suffix (Tape & Reel, DO-201AD) is no longer in production. ## Through-hole axial — retrofit and handling The DO-201AD axial package is a standard through-hole form factor. When replacing this diode in a legacy board, confirm the lead spacing and body diameter match the existing footprint.","metaTitle":"STTH212RL Fast Recovery Diode, 1200 V 2 A, 75 ns trr","metaDescription":"STTH212RL 1200 V 2 A fast recovery rectifier, 75 ns trr, DO-201AD axial.","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)","Technology":"Standard","Mounting Type":"Through Hole","Package / Case":"DO-201AD, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STTH21","Capacitance @ Vr, F":"-","Supplier Device Package":"DO-201AD","Reverse Recovery Time (trr)":"75 ns","Current - Reverse Leakage @ Vr":"10 µA @ 1200 V","Voltage - DC Reverse (Vr) (Max)":"1200 V","Current - Average Rectified (Io)":"2A","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"1.75 V @ 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9197f644d8a2de13cedf274f7aa484e8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is STTH212RL obsolete?","answer":"Yes, STMicroelectronics lists the STTH212RL as Obsolete.
