Phototransistor Output - AC Sensing Input Optocouplers

Overview
Products
Technical Documentation
The family of Phototransistor Output AC Sensing Input Optocouplers from ON Semiconductor consists of two gallium arsenide infrared emitting diodes, connected in inverse parallel, driving a silicon phototransistor output in 4, 6, or 8-pin packages. The devices offer a variety of Current Transfer Ratio (CTR) ranges from 20% to 600% at IF = ±1 mA, VCE = 5 V, TA = 25ºC. Other ideal performance characteristics and features of these devices include bi-polar emitter input, built-in reverse polarity input protection, bidirectional AC Input, protection Against Reversed DC Bias, Guaranteed CTR Symmetry of 2:1 Maximum, and half pitch leads for optimum board space savings. The devices achieve the following safety and regulatory approvals: UL1577 #E90700, DIN EN/IEC60747-5-5, VDE #136480, and CSA #1201524. Applications for the devices include AC-DC Merchant Power Supplies, Consumer Appliances, and Industrial Motors.
