Isocom ISQ203X 4-Channel Optocoupler DIP16 5.3kV 225% CTR

Isocom ISQ203X 4-Channel Optocoupler is a 16-pin DIP optically coupled isolator with four channels and a 5.3kVrms isolation rating, providing galvanic isolation between circuit sections that operate at different potentials.

The ISQ203X integrates infrared light-emitting diodes (LEDs) with NPN silicon phototransistors to provide reliable signal isolation. It is designed to protect sensitive circuitry from voltage spikes and ground loop interference, and it features a 70V minimum collector-emitter breakdown voltage (BVCEO) and a forward current rating of 50mA for demanding industrial environments.

Key Features

• Four-channel, high-density design in a standard 16-pin DIP (Dual In-line Package)
• Isolation voltage of 5.3kVrms (7.5kVpk) for safe signal transmission between systems
• Current Transfer Ratio (CTR) of 225% minimum for efficient signal transmission and good sensitivity
• Provides electrical isolation between input and output, helping to prevent noise and voltage transients from affecting connected equipment
• Compact DIP package suitable for high-density mounting on printed circuit boards (PCBs)
