ISOCOM ISQ203X 4-Channel Optocoupler, DIP16, 5.3kV, 225% CTR

The ISOCOM ISQ203X is a high-density, 4-channel optically coupled isolator in a standard 16-pin DIP (Dual In-line Package) format. It integrates infrared light-emitting diodes (LEDs) with NPN silicon phototransistors to provide reliable galvanic isolation, making it a critical component for protecting sensitive circuitry from voltage spikes and ground loop interference.

Designed for robust performance, this optocoupler features a high isolation voltage of 5.3kVrms (7.5kV peak), ensuring safe signal transmission between systems operating at different potentials. Its 70V minimum collector-emitter breakdown voltage (BVCEO) and ability to handle a forward current of 50mA make it suitable for demanding industrial environments.

Key Features

• Provides electrical isolation between input and output, preventing noise and voltage transients from damaging connected equipment.
• High Current Transfer Ratio (CTR) of 225% minimum ensures efficient signal transmission with good sensitivity.
• All electrical parameters are 100% tested for guaranteed reliability and performance consistency.
• Compact DIP package allows for high-density mounting on printed circuit boards (PCBs), saving valuable board space.

Applications

This component is ideal for isolating digital or analogue signals in a wide range of electronic systems. Its primary uses include industrial system controllers, computer peripherals, and various signal processing applications where clean, noise-free communication between different voltage domains is essential.
