余白上35mm Auxiliary Switch Diodes for Snubber SARS01, SARS02, SARS05, SARS10 Data Sheet Description Package The SARS(1) is an auxiliary switch diode especially SARS01 (Axial φ 2.7 / φ 0.60) designed for snubber circuits, which are used in the primary sides of flyback switched-mode power supplies. (1) (2) Being capable of reducing the ringing voltage generated at power MOSFET turn-off, the SARS02 (Axial φ 4 / φ 0.78) SARS-incorporated snubber circuits allow better cross regulation of multiple outputs. (1) (2) The SARS can also improve power supply efficiency s by partially transferring such ringing voltage into the n SARS05 (SJP 4.5 mm × 2.6 mm) secondary side of a power supply unit. g i Features s e (1) (2) ● Improves Cross Regulation D ● Reduces Noise ● Improves Efficiency w e Applications N (1) (2) (1) Cathode For switched-mode power supplies (SMPS) with (2) Anode flyback topology such as: r o ● White Goods SARS10 (TO220F-2L) f ● Adaptor ● Industrial Equipment d (1) e Typical Application d (2) n Clamp snubber e m CS RS1 (1) (2) (1) Cathode side m (2) Anode RS2 o Not to scale SARSc e R Selection Guide Controller Power Supply t R Part I VF Output Power, o AC/DC converter IC S2 Number F(AV) (max.)

The voltage rating is selected according to the voltage s subtraced the input voltage from the peak of VDS. n g ● R S1 i RS1 is the bias resistance to turn off the SARS, and is s 100 kΩ to 1 MΩ. e Since a high voltage is applied to R that has high D S1 resistance, the following should be considered according to the requirement of the application: w - Select a resistor designed for electromigration, or - Connect more resistors in series so that the applied e N voltages of individual resistors can be reduced. The power rating of resistor should be selected from the measurement of the effective current of R based on r S1 actual operation in the application. o f ● RS2 d R is the limited resistance in the energy discharging.
