PC-17T1, PC-17T2, PC-17T4 are three photocouplers, which have small package size, low power consumption, high reliability and so on. These products are suitable for different voltage and current interconnection, such as sensor signal isolation, industrial control, communication equipment, etc.
The PC-17T series from KODENSHI are optocouplers that combine a Gallium Arsenide infrared emitting diode with a silicon NPN phototransistor. The PC-17T1 provides a single channel in a 4‑pin DIP, the PC-17T2 offers two channels in an 8‑pin DIP, and the PC-17T4 contains four channels in a 16‑pin DIP.
Key specifications include a minimum collector‑emitter voltage of 35 V, a current transfer ratio of at least 50 % (IF=5 mA, VCE=5 V), and an isolation voltage of AC2500 V. Electrical characteristics such as forward current (50 mA), reverse voltage (5 V), forward voltage (1.15‑1.30 V), and capacitance (up to 30 pF) are listed, along with temperature ranges for storage and operation.
