FUF4001.. FUF4007 1 Amp. Glass Passivated Ultrafast Recovery Rectifier • Glass Passivated Junction • High current capability • The plastic material carries U/L recognition 94 V-0 • Terminals: Axial Leads • Polarity: Color band denotes cathode
The FUF4001‑FUF4007 series are 1 A glass‑passivated ultrafast recovery rectifiers offered in DO‑41 packages. They provide high‑speed switching with low forward voltage drop and are suitable for applications requiring fast recovery times.
The sheet lists maximum ratings such as peak reverse voltage (50‑1000 V), RMS voltage, DC blocking voltage, forward voltage drop, reverse current, thermal resistance, junction capacitance (15 pF at 1 MHz), and operating temperature range (‑65 °C to +150 °C). Characteristic curves for forward current derating and forward voltage versus temperature are also included.
