The PC-16T1 is a 4-pin single-channel photocoupler. Its features include small package size, minimum collector-emitter voltage of 35V, minimum current transfer ratio of 50% (at IF=1mA, VCE=5V), and electrical isolation voltage of AC2500Vrms. This photocoupler is suitable for applications such as interface between two circuits of different potential, programmable logic control, power supply, and computer terminals.
The PC-16T1 photocoupler integrates a Gallium Arsenide infrared emitting diode with a silicon NPN phototransistor in a 4‑pin package. It offers a small package size, a minimum collector‑emitter voltage of 35 V, and a current transfer ratio of at least 50 % (IF=1 mA, VcE=5 V). The device is rated for AC 2500 V rms isolation and meets UL file No. E107486.
Typical applications include interfacing circuits with different potentials such as vending machines, cordless phones, fax machines, motor control, PLCs, power supplies, and computer terminals. Detailed electrical characteristics, maximum ratings, and performance graphs are provided for design reference.
