Photocoupler
K301 • K302 • K304
These Photocouplers consist of a Gallium Arsenide Infrared Emitting Diode and a Silicon NPN Photo Darlington transistor per a channel. The K301 has one channel in a 4-pin mini-flat SMD package. The K302 has two channels in a 8-pin mini-flat SMD package. The K304 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=1mA, VCE=2V) • Electrical Isolation Voltage : AC3750Vrms
APPLICATIONS
• Interface between two circuits of different potential • Telephone Line Receiver • Automatic Vending Machine • Power Supply Regulators
