The Vishay Dale H11A1 is an industry-standard single-channel optocoupler with a phototransistor output and base connection. It utilizes a gallium arsenide infrared LED and a silicon NPN phototransistor, providing robust isolation through Vishay's double molding process. This device offers an isolation rated voltage of 4420 Vrms and features an input-output coupling capacitance of less than 0.5 pF.
The H11A1 is housed in a standard dual-in-line 6-pin package (6-DIP) suitable for through-hole mounting. It operates within a temperature range of -55°C to 100°C and handles an input current of up to 60 mA. Key electrical characteristics include a Vce saturation of 400mV (max) and a minimum current transfer ratio of 50% at 10mA.
Applications for the H11A1 include AC mains detection, reed relay driving, switch mode power supply feedback, telephone ring detection, logic ground isolation, and logic coupling with high-frequency noise rejection. Agency approvals include UL, cUL, DIN EN 60747-5-5, BSI, CQC, and FIMKO.
