Overview
The BYW27-50 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 1 A and a peak forward surge current (IFSM) of 50 A at 50 Hz or 55 A at 60 Hz. The maximum repetitive reverse voltage (VRRM) is 50 V. Forward voltage (VF) is less than 1.3 V at 1 A and 25°C. Reverse leakage current (IR) is under 0.2 µA at 25°C and under 5 µA at 100°C when VR equals VRRM. Typical junction capacitance is 15 pF at 4 V reverse bias. Reverse recovery time (trr) is typically 1500 ns. Thermal resistance from junction to ambient is less than 45 K/W, and junction to leads is less than 15 K/W.
