Photocoupler
K401 • K402 • K404
These Photocouplers consist of two Gallium Arsenide Infrared Emitting Diodes and a Silicon NPN Photo Darlington transistor per a channel. The K401 has one channel in a 4-pin mini-flat SMD package. The K402 has two channels in a 8-pin mini-flat SMD package. The K404 has four channels in a 16-pin mini-flat SMD package.
FEATURES
• Mini-flat Package • Collector-Emitter Voltage : Min.30V • Current Transfer Ratio : Type 600% (at IF=A1mA, VCE=2V) • Electrical Isolation Voltage : AC3750Vrms
APPLICATIONS
• AC Signal Input • Interface between two circuits of different potential • Automatic Vending Machine • Copiers, Industrial Robots
