Super barrier rectifier diode with 25% lower Vf drop compared to std diode

Diodes Inc. has unvieled the SBR1U400P1 super barrier rectifier. According to Diodes the rectifier has a forward voltage some 25% lower than standard p-n diode alternatives and has been designed to increase the efficiency of off-line LED drivers.

This 1A, 400V rated super barrier rectifier suits both bridge, with a 120VAC input, and buck stages of driver circuits. This rectifier is suggested for application in LED light bulbs, lighting ballasts, signage and street lighting. The rectifier offers a forward voltage of less than 0.65V for a current of 1A at 125°C means that a significant reduction in power consumption is now possible for a wide range of off-line LED driver circuits. This rectifier comes in a PowerDI123 package. The SBR1U400P1 has a high-speed switching performance with a reverse recovery time of just 85ns (If=0.5A, Ir=0.5A, Irr=0.25A).
