Nexperia – 40V, 0.5A Schottky barrier rectifier has a low forward voltage


The PMEG4005CEA from Nexperia, the discrete power components business recently spun-off from NXP Semiconductors, is a planar Schottky barrier rectifier with a low forward voltage. This makes it suitable for low-voltage rectification and for applications in which power-conversion losses must be kept to a minimum.

The PMEG4005CEA is housed in a SOD323 (SC-76) surface-mount plastic package which has a footprint of just 1.8mm x 1.35mm. It features an integrated guard ring for stress protection.

The rectifier is rated for a maximum reverse voltage of 40V, and an average forward current of up to 0.5A at a switching frequency of 20kHz and a temperature of up to 135°C. Typical forward voltage is just 550mV, measured at a pulsed forward current of 500mA and a junction temperature of 25°C.
