The 4N37M is a general purpose optocoupler with a gallium arsenide infrared emitting diode and a silicon phototransistor in a standard PDIP6 package. It provides a minimum current transfer ratio of 100% at I_F = 10 mA and V_CE = 10 V. The device meets UL1577 with a 4,170 VAC isolation rating for one minute and DIN-EN/IEC60747-5-5 with an 850 V peak working insulation voltage. Electrical isolation features include an external creepage and clearance of at least 7 mm and a distance through insulation of at least 0.5 mm. The operating temperature range is -40 °C to +100 °C, and the maximum collector-to-emitter
