Choosing Standard Recovery Diode or Ultra-Fast Diode in Snubber

Texas Instruments

Published Date: 10/09/2015

Description

While using a Snubber circuit is very common for flyback design, suppressing the stress of MOSFET is not the only design consideration for snubber. The Snubber circuit will also impact the efficiency, standby power, and EMI performance. This paper reviews the working principle of snubber and illustrates the diode selection for RCD/R2CD and TVS Snubber.
