BY399 Fast Recovery Diode 3A 800V

Description

BY399 Fast Recovery Diode 3A 800V The BY399 is a high-performance fast recovery rectifier diode engineered for applications requiring efficient switching and minimal power loss. With a maximum repetitive peak reverse voltage of 800V and an average rectified forward current of 3A, it excels in medium to high voltage rectification tasks. Its fast reverse recovery time of 500ns reduces switching losses, making it an excellent choice for high-frequency operations. Encased in a durable DO-201AD package, the BY399 delivers reliable and robust performance across a wide range of power electronics applications. Features Fast switching with a reverse recovery time of 500ns High current handling: 3A average, 100A surge Low forward voltage drop: 1.3V at 3A Low reverse leakage current: 10μA at 800V Wide operating temperature range: -65°C to +150°C High reliability and surge current capability Specifications Parameter Value Maximum Repetitive Peak Reverse Voltage (V RRM ) 800V Maximum RMS Voltage (V RMS ) 560V Maximum DC Blocking Voltage (V DC ) 800V Average Rectified Forward Current (I O ) 3.0A Non-Repetitive Peak Forward Surge Current (I FSM ) 100A Maximum Instantaneous Forward Voltage (V F ) 1.3V at 3.0A Maximum Reverse Current (I R ) 10μA at 800V Reverse Recovery Time (t rr ) 500ns Typical Junction Capacitance (C J ) 60pF Operating Temperature Range -65°C to +150°C Package Type DO-201AD (DO-27) Mounting Position Any Applications High-frequency rectification in power supplies Switch-mode power supplies (SMPS) Inverters and DC-DC converters Freewheeling diodes in motor drives Snubber circuits for transient suppression Bootstrap diodes in half-bridge configurations DataSheet BY399
