The HMA121 series is a family of 4-pin mini-flat package optocouplers containing a gallium arsenide infrared emitting diode and a silicon phototransistor, with a lead pitch of 2.54 mm and a maximum standoff height of 2.4 mm. The devices provide 3750 Vrms isolation, with a continuous collector current of 80 mA and a collector-emitter voltage rating of 80 V. They operate from -40°C to +100°C, support infrared reflow soldering up to 230°C for 30 seconds, and meet UL, CSA, BSI, and VDE safety certifications. The HMA121R4 variant corresponds to the tape and reel packaging option with 2500 units per reel and 180° rotation, consistent with the series' standard features.
