Product Brief
Infineon Bridge Rectifier
Key Features:
 Schottky Diode rectifier with fast
switching speed and low voltage drop
for high energy efficiency rectifiers
 Very small systems
 Full bridge and Half bridge
combinations available
 Suitable also for advanced reverse
polarity protection
E N E R G Y E F F I C I E N T circuit design could have these days crucial
significance for the success of a product.
Since decades bridge rectifier is the state of the art for circuit for all DC Power
supply. A bridge rectifier makes use of four diodes in a bridge arrangement to
achieve full-wave rectification. The energy efficiency of a rectifier is determined by
the forward voltage drop and the switching speed of the diodes.
Rectifiers build by Schottky have such a very low forward voltage drop and switching
speeds that approach zero time. This makes them ideal for energy efficient output
stages of switching power supplies.
Target Applications:
 Rectifier for LED illumination
 Energy saving Lamps
 Mobil Battery charger
(Mobil-Phones, Digital-Cameras, PDAs)
 Toys
The full bridge rectifier is coming in the tiny SOT143 .
