The BY203-20STR is a fast avalanche sinterglass diode from Vishay General Semiconductor, part of the BY203 series. It features a repetitive peak reverse voltage of 2000 V and an average forward current of 250 mA. The diode offers a peak forward surge current of 20 A (tp = 10 ms, half sine wave) and a forward voltage of 2.4 V maximum at 200 mA. Its reverse recovery time is 300 ns, classifying it as a fast recovery diode. The device includes a non-repetitive reverse avalanche energy rating of 10 mJ at I(BR)R = 0.4 A.
The diode is designed for fast rectification and switching applications, particularly in TV line output circuits and switch mode power supplies. It features a glass passivated junction and is hermetically sealed in a SOD-57 sintered glass case. The package has plated axial leads solderable per MIL-STD-750, method 2026, and a color band denotes the cathode end. The junction temperature range is -55°C to +150°C, and the storage temperature range is -55°C to +175°C. The component weighs approximately 369 mg.
