Fairchild Semiconductor has developed a new half-pitch mini-flat package configuration for optocouplers
Fairchild Semiconductor has developed a new half-pitch mini-flatpackage configuration for optocouplers. The half-pitch mini-flatpackage features four surface-mount leads on 1.27mm spacing, andhas a 61% smaller footprint than a four-pin dual-inline surfacemount package. This makes it ideal for telecommunications, powerconversion, and industrial control applications where smallcomponent size is crucial.

The first products to be offered inthe half-pitch mini-flat package are the HMHA281, HMHA2801 andHMHAA280 optocouplers.
Fairchild's HMHA series optocouplersconsist of a single gallium arsenide infra-red emitting diode (DCinput) driving a silicon phototransistor.
The HMHA281 has acurrent transfer ratio (CTR) of 50-600% and the HMHA2801 has aCTR of 80-600% at a forward current of 5mA.
The HMHAA optocouplerconsists of two gallium arsenide infra-red emitting diodes,connected in inverse parallel (AC input), driving a siliconphototransistor.
The HMHAA280 has a CTR of 50-600%, at a forwardcurrent of 15mA.
The HMHA281, HMHA2801, and HMHAA280 optocouplersare available in tape and reel configuration, and they are directreplacements for NEC, Sharp and Toshiba.
All full-pitch andhalf-pitch mini-flat package optocouplers are BSI, CSA, UL, andVDE certified.
Samples and production quantities are availablenow..
