Characteristics STPS1L30U Units The STPS1L30U surface-mount Schottky rectifier has been
designed for applications requiring low forward drop and
small foot prints on PC boards. Typical applications are in disk
drives, switching power supplies, converters, free-wheeling
diodes, battery charging, and reverse battery protection.
Small foot print, surface mountable
Very low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability

(2) Formula used: TC = TJ - (Pd + PdREV) x RthJC ;
Pd = Forward Power Loss = IF(AV) x VFM @ (IF(AV) / D) (see Fig. 6);
PdREV = Inverse Power Loss = VR1 x IR (1 - D); IR @ VR1 = 80% rated VR
