HALF PITCH MINI-FLAT PACKAGE

4-PIN OPTOCOUPLERS

HMHAA280

HMHA2801 SERIES

HMHA281

DESCRIPTION

The HMHA281, HMHA2801 Series consists of a gallium arsenide infrared emitting diode driving a silicon

phototransistor in a compact 4-pin mini-ﬂat package. The lead pitch is 1.27 mm.

The HMHAA280 series consists of two gallium arsenide infrared emitting diodes, connected in inverse

parallel, driving a single silicon phototransistor in a compact 4-pin mini-ﬂat package. The lead pitch is 1.27mm.
