Ultra-low forward voltage Schottky diodes

December 05, 2013 // By Graham Prophet
Toshiba Electronics has extended its family of surface mount Schottky barrier diodes (SBDs) with a new device, CxS15S30, for improved forward voltage and reverse current performance; it handles up to 1.5A

The CxS15S30 SBD offers 1.5A and 30V maximum ratings for average rectified current and peak reverse voltage, respectively. Package options comprise an ultra-compact LGA type CST2C package (CCS15S30) measuring 1.6 x 0.8 x 0.48 mm, and a standard SOD-323 package (CUS15S30).

Toshiba says its diode will be particularly suited to space-limited applications where high current handling and low forward voltage (VF) characteristics are key requirements. The CxS15S30 delivers the high-efficiency operation demanded by battery-powered and other power-sensitive designs. A low typical forward voltage rating of VF = 0.39V at 1.5A and the low typical reverse current of only 200 µA ensures lowest loss operation in most common applications such as LED backlight circuits or current backflow prevention in battery charging. A total typical diode capacitance of 200 pF means that the CxS15S30 can also be used in general high-speed switching applications.
