Characteristics 10BQ030 Units
The 10BQ030 surface-mount Schottky rectifier has been de-
signed 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
