Overview
The HMHA281R2V is a phototransistor output optocoupler produced by onsemi. It is part of the HMHA281 series, which consists of a gallium arsenide infrared emitting diode driving a silicon phototransistor. This device is packaged in a compact 4-pin mini-flat package with a lead pitch of 1.27 mm. Although it is not recommended for new designs (with FODM217x being the suggested replacement), it remains available for existing applications. The HMHA281R2V is Pb-free and RoHS compliant, ensuring environmental sustainability.
