12 Why TO-277B from Littelfuse? DST series Ultra-Low VF Schottky, TO-277B

13 Advantage in Auto application Most Automotive infotainment applications are up to 10A D-PAK (TO-252) has been popular for 5-10A range Littelfuse offers up to 10A in Auto-grade TO-277B TO-277B foot print area 1/3 of D-PAK, 1/6 of D 2 -PAK TO-227B 1.1mm high, D-PAK 2.3mm high TO-277B D-PAK 13

14 Footprint & Dimensions 14

15 Advantage of Ultra-Low V F Schottky Trench-MOS structure to further enhance low V F characteristics Lower conduction loss for higher efficiency in converter and lower heat generation in reverse blocking diode DST10100S-A (10A, 100V) V F specification 15

16 What Does it Offer? Features u Provides ultra-low forward voltage drop (V F ) Benefits u Reduced thermal and electrical conduction losses, thereby improving system efficiency u Provides fast switching speed u Can be used in very high-frequency applications with minimal switching loss u Offers high junction temperature capability u High reliability in high ambient temperatures or applications with minimal cooling available u Requires 1/3 of foot print compared to conventional D-PAK products u Enable much smaller device design, or more functions in same size 16

17 Key Advantages DST Series Schottky Barrier Rectifiers (Ultra-Low VF Schottky) offer ultra-low forward voltage drop and less heat dissipation vs. conventional diodes, thereby reducing thermal and electrical conduction losses and improving system efficiency. DST Series Schottky Barrier Rectifiers (Ultra-Low VF Schottky) offer fast switching speeds and are suitable for high frequency with minimal switching loss applications. High junction temperature capability improves reliability in high ambient temperatures or applications with minimal cooling available. 17
