The RGF1M is an ultra-fast, high-temperature resistant, and high-voltage rectifier diode manufactured by EIC Semiconductor. It features a forward voltage of 1.3 volts at 1 ampere (1A), a turn-on delay of 500 nanoseconds (500ns), a reverse breakdown voltage of 1,000 volts (1kV) and conforms to SMA (surface mount assembly) and RoHS standards. This diode also offers low leakage, fast recovery time, and low forward voltage drop, making it suitable for high-frequency rectification and high surge current applications.
