PC-17L1, PC-17L2, PC-17L4 Photocouplers, small package size, high isolation voltage, high reliability, widely used in various analog and digital circuits isolation, such as computer terminals, programmable logic controller, power supply, sensors, etc.
The PC-17 series photocouplers from KODENSHI are optically isolated devices that combine a GaAs infrared emitting diode with a silicon NPN phototransistor. The PC-17L1 offers a single channel in a 4‑pin DIP, the PC-17L2 provides two channels in an 8‑pin DIP, and the PC-17L4 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 %, and an isolation voltage of AC 5000 Vrms. The devices are rated for forward current up to 50 mA, operate from –30 °C to +100 °C, and are suitable for applications such as vending machines, cordless phones, motor control, PLCs, power supplies, and computer terminals.
