Schottky barrier diodes look for handheld niche

22 September 2004 Power Electronics / Power Management Infrastructure

Torex Semiconductor has two new series of Schottky barrier diodes, the XB01SB04A2BR and the XB0ASB03A1BR. Schottky diodes offer a much lower forward voltage drop than standard switching diodes which makes them especially useful in high-current low-voltage applications, particularly in handheld and portable equipment.

The XB0ASB03A1BR, supplied in a compact SOD-323 package, has an average rectification current of 0,5 A and, when operating at 0,5 A, a forward voltage of 410 mV. Reverse voltage is 20 V and reverse current typically 35 μA. The XB01SB04A2BR has an average rectification current of 1 A and a forward voltage of 500 mV at 1 A. Reverse voltage is 40 V and reverse current typically 6 μA. It comes in a compact SOD-123 package. Both devices feature a forward surge current of 10 A and a junction temperature of 125°C.
