Photocoupler
K201 • K202 • K204
These Photocouplers consist of two Gallium Arsenide Infrared Emitting Diodes connected in a reverse-paralled configuration for AC-input and a Silicon NPN Phototransistor per a channel. The K201 has one channel in a 4-pin mini-flat SMD package. The K202 has two channels in a 8-pin mini-flat SMD package. The K204 has four channels in a 16-pin mini-flat SMD package.
FEATURES
• Mini-flat Package • Collector-Emitter Voltage : Min.50V • Current Transfer Ratio : 50% Min. (at IF= ¡¾5mA, VF=5V) • Electrical Isolation Voltage : AC3750Vrms
APPLICATIONS
• AC Signal Input • Interface between two circuits of difference Potentail • Cordless Phone • Programmable Logic Control
