Diodes Incorporated has designed the SBR1U400P1 super barrier rectifier to increase the efficiency of off-line LED drivers.

This 1A, 400V rated part suits both bridge, with a 120VAC input, and buck stages of driver circuits.

The rectifier's typical ultra-low forward voltage is less than 0.65V for a current of 1A at 125°C. It is provided in Diodes' own high performance PowerDI®123 package for best possible heat dissipation.

SBR1U400P1 also has a high-speed switching performance with a maximum reverse recovery time of just 85ns (If=0.5A, Ir=0.5A, Irr=0.25A). The rectifier exhibits a soft recovery and removes ringing, resulting in an overall reduction in electrical noise generation.

Applications include LED light bulbs, lighting ballasts,signage and street lighting.
