The Diodes Incorporated SF30BG-B is a super-fast, glass-passivated rectifier diode designed for efficient power conversion and robust reverse blocking in industrial and embedded electronics. With 100 V repetitive reverse voltage (VRRM) and 3 A average rectified current (IO) in a DO-201AD through-hole package, it delivers low loss, stable thermal behaviour, and dependable surge capability for SMPS, DC–DC converters, and general rectification stages.
The SF30BG-B offers a proven balance of fast recovery, low leakage, and rugged DO-201AD construction, ideal for cost-sensitive rectification and protection tasks. For new builds, confirm lifecycle status and pre-qualify a pin-for-pin, super-fast alternative with equivalent 100 V/3 A capability and similar TRR to preserve efficiency and EMI margins.
