HMA121 - Brand New onsemi Transistor Output Optocouplers
-
Description
The HMA121 is part of the HMA124 and HMA2701 series, which consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor. It is packaged in a compact 4-pin mini-flat package with a lead pitch of 2.54 mm. The HMAA2705, on the other hand, consists of two gallium arsenide infrared emitting diodes connected in inverse parallel, driving a single silicon phototransistor. It also comes in a compact 4-pin mini-flat package with a lead pitch of 2.54mm.
