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.
Features
1. Improving cross regulation
2. Reducing noise
3. Improving efficiency
Application:
For Switched-mode power supply (SMPS) with flyback topology such as for the followings:
1. White goods
2. Adaptor
3. Industrial equipment
Typical Application Clamp snubber CS RS1 RS2 SARS SARS05 (SMA 4.5×2.6) SARS10 (TO220F-2L) Not to Scale Lineup ● VRM=800V RS2 External component Products SARS01 IF (AVG) VF (max.) 1.2 A 0.92 V Power supply output power, PO- ~50W SARS02 1.5 A 0.92 V ~100W SARS05 1 A 1.05 V ~50W Built-in 22Ω SARS10 0.3 A 13 V ~300W – PO is the reference value at selection. The temperature of SARS should be measured based on actual operation in the application. Cont. AC/DC converter IC SARS01/02/05/10 – DSJ Rev.1.0 SANKEN ELECTRIC CO.,LTD.
