KODENSHI K301

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
