Diodes shrink for low power
rectification
The latest miniature surface-mount diodes from Rohm offer low forward voltage and reverse current ratings and are just half the height and one-seventh the volume of previous generations of devices.

Rohm has launched a device that will simplify the design of mobile phones requiring full colour backlights by delivering the increased voltages and driving functionality demanded by white LEDs.
Dual-channel regulators save space
Two new voltage regulators from Rohm Electronics offer simplified circuit layout and reduced component count by combining stable dual outputs with built-in protection.
The RSR264-400 rectifying diode is designed for automotive applications.
Each device is supplied in a small power mould PMDU (SOD123) package measuring just 2.6 x 1.6 x 0.8mm.
This compares with dimensions of 4.5 x 2.6 x 2.0mm for previous generations of diodes in SMA power mould packages.
The new RSR264-400 offers an average rectified forward current (IO) of 0.7A and has a peak DC reverse voltage (VR) rated at 400V.
Both the RB160M-30 and RB161M-20 diodes can deliver average rectified forward currents of 1A and have VR ratings of 30 and 25V, respectively.
At the average IO the RSR264-400 has a typical forward voltage drop (VF) of 1.10V.
Typical VF for the RB160M-30 is only 0.43V.
Target parameter for the RB161M-20 is an industry-leading, ultra-low VF of 0.31V at an IF of 1A.
Both the RSR264-400 and the RB160M-30 are designed for low reverse current (IR) operation with respective ratings of just 10uA and 9.0uA.
All of the new diodes are designed for maximum reliability and can handle forward current surge peaks of between 25 and 30A depending on the particular device.
Maximum junction temperature for the RSR264-400 is 150C.
The RB160M-30 and RB161M-20 both offer a maximum junction temperature of 125C.
