Schottky barrier diodes look for handheld niche

Torex Semiconductor Europe has two new series of Schottky barrier diodes, the XB01SB04A2BR and the XB0ASB03A1BR.

Torex Semiconductor Europe 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.

Their very low forward voltage brings with it a high current capability, ultra fast switching behaviour and low power dissipation, making them ideal for use with DC/DC convertors.

The XB0ASB03A1BR, supplied in a compact SOD-323 package, has an average rectification current of 0.5A and, when operating at 0.5A, a forward voltage of 410mV.

Reverse voltage is 20V and reverse current typically 35uA.

The XB01SB04A2BR has an average rectification current of 1A and a forward voltage of 500mV at 1A.

Reverse voltage is 40V and reverse current typically 6uA.

It comes in a compact SOD-123 package.

Both devices feature a forward surge current of 10A and a junction temperature of 125C.

In addition to the rectification of compact DC/DC convertors, the XB01SB04A2BR and XB0ASB03A1BR are also ideal for a diverse range of other uses.

These include: the reduction of power losses in notebook PCs, mobile phones, minidisk players, and PDAs; surge absorption caused by the counter force of compact motors; and protection against reverse connection of the battery.
