The VSD3913R diode is a single, symmetrical, low voltage, ultra-fast, soft-recovery rectifier. It is a special diode optimized for switching power applications including, but not limited to, dc-dc converters. The VSD3913R is capable of high frequency switching, up to 100 kHz, with less reverse-recovery losses and faster switching times. The better reverse-recovery characteristics are the result of the soft-recovery process that produces significantly less electromagnetic interference. This diode has a low maximum junction temperature of 150°C with a high-temperature storage capability due to its thin-layer epitaxial construction.

The VSD3913R is designed to reduce reverse leakage by using an epitaxial process. This process also eliminates bipolar transients associated with recovery process and reduces diode capacitance. This diode is also capable of withstanding high surge currents without thermal runaway, making it ideal for many power switching applications.

The application field of VSD3913R diode includes, but is not limited to, dc-dc converter, high-frequency aftermarket converter, clock converter and AC-DC converters. It can also be used in LED lighting or any application with high surge currents. Moreover, VSD3913R can withstand temperatures up to 150°C and store constant temperature up to 400°C, making it an ideal choice for high-temperature operation circuits.

The working principle of the VDS3913R diode is based on a simple voltage-controlled operation. When a voltage is applied to the diode, the junction will emit electrons that will flow in the forward direction. This phenomenon is known as forward biased. The electrons will flow through the diode and will reach its peak voltage until the maximum reverse current is reached. When the current is reduced, the electrons stop flowing and reverse bias is formed. This process is known as the reverse-bias. The electrons will start flowing in the opposite direction, creating a steady-state current. This process is known as the soft-recovery process.

In conclusion, the VSD3913R diode is a single, symmetrical, low voltage, ultra-fast, soft-recovery rectifier. It is designed to reduce reverse leakage by using an epitaxial process, and can handle high surge currents without any thermal runaway. Its application field includes, but not limited to, dc-dc converter, high-frequency aftermarket converter, clock converter, AC-DC converters and LED lighting. The working principle of the diode is based on a simple voltage-controlled operation and the soft-recovery process.
