Schottky Barrier Rectifiers are Small on Size, Big on Power

Combining 490mV forward voltage and peak-current capability of 25A in a 1mm high package, the NXP Semiconductors PMEG4010 low forward-voltage rectifier diode increases efficiency in space-constrained applications.

The PMEG4010 is a member of NXP’s planar Maximum Efficiency General Application (MEGA) Schottky barrier rectifier family. It is available in both the SOD123W and the SOD128 packages that are footprint-compatible with industry-standard SMA packages, but have a 50% lower profile. This is achieved without trading power-handling capability by using NXP’s FlatPower package technology, which features clip-bond construction and an integrated guard ring for stress protection.

As well as its high peak-current capability, the PMEG4010 withstands 1A average continuous current, allowing use in a wide range of power-management circuits, step-down and synchronous converters, and freewheeling circuits for inductive loads andmotor drives. The ultra-low forward voltagemakes the PMEG4010 especially valuable in battery-powered devices and other systems prioritising energy savings and efficiency gains.
