Schottky diodes aid power-sensitive
applications
Rohm Electronics has expanded its family of Schottky diodes with seven new ultrasmall surface-mount devices for low-power rectification and high-speed switching in space-limited applications.
Rohm Electronics has expanded its family of Schottky diodes with seven new ultrasmall surface-mount devices that are designed for low-power rectification and high-speed switching in space-limited and power-sensitive applications Ideally suited to battery-powered and portable equipment, the new high-reliability Schottky diodes feature forward voltage ratings down to just 0.28V (at a forward current of 1mA) and reverse current ratings as low as 0.5uA

Light sensors save power in portable displays
Ambient light sensors feature spectral sensitivity characteristics similar to the photopic luminous efficiency of the human eye.
All of the devices are supplied in ultra small mould type packages with footprints that range from 2.0 x 1.25mm down to 1.2 x 0.8mm.
Board mounting profiles start at 0.5mm.
The seven new devices comprise the RB480Y and RB481Y in an EMD4 package, the RB731XN in a UMD6 package, the RB715W in EMD3 and UMD3 package styles, the RB751S-40, which is available in an EMD2 package, and the UMD2 RB751V-40.
Average rectified forward current (IO) for the RB480Y and RB481Y is rated at 100mA, while all of the other devices offer an IO of 30mA.
At 0.28V, the RB481Y diode has the lowest forward voltage characteristic of the new range, while the RB751S-40 and RB751V-40 have the lowest reverse current ratings at 0.5uA.
The forward voltage of the RB480Y is specified as 0.38V, with the RB715F, RB715W, RB731XN and both the RB751S-40 and RB751V-40 all having forward voltage ratings of 0.37V.
Reverse currents are specified as 1.0uA for the RB480Y, RB715F, RB715W and RB731XN.
Maximum reverse voltages are 30 or 40V depending on the device chosen.
All of the new Schottky diodes can operate with junction temperatures of up to 125C.
