Description

Auxiliary Switch Diode for Snubber SARS01 / SARS05 / SARS10. The SARS02 is the auxiliary switch diode for snubber circuit, used in the primary side clamp snubber circuit of switched-mode power supplies with fly back topology. Since the ringing voltage at turning off the power MOSFET is more reduced by the clamp snubber circuit using SARS, the cross regulation of multi-outputs is improved.

Being capable of reducing the ringing voltage generated at power MOSFET turn-off, the SARS01/05-incorporated snubber circuits allow better cross regulation of multiple outputs. The SARS01/05 can also improve power supply efficiency by partially transferring such ringing voltage into the secondary side of a power supply unit.

Description

B30A45VC is 45V, 30A, Schottky Barrier Diode. A Schottky Barrier Diode (SBD), often simply referred to as a Schottky diode, is a semiconductor device that provides rectification and switching functions. It is named after the German physicist Walter H. Schottky, who contributed to its development. Schottky diodes are characterized by their low forward voltage drop and fast switching capabilities, making them useful in various electronic applications.

1. Metal-Semiconductor Junction: Unlike conventional PN junction diodes, Schottky diodes have a metal-semiconductor junction. The metal side (anode) of the diode is placed in contact with a semiconductor material (cathode), forming a rectifying junction.

2. Low Forward Voltage Drop: One of the primary advantages of Schottky diodes is their low forward voltage drop (typically around 0.2 to 0.5 volts). This leads to less power loss and faster switching compared to standard PN diodes, which have higher forward voltage drops.

3. Fast Switching Speed: Schottky diodes have a fast reverse recovery time due to their metal-semiconductor junction structure. This makes them suitable for high-frequency applications and fast-switching circuits.

1. Average Output Rectified Current: IO=30A.
