Optocoupler Transistor Output DIP 4-Pin 50mA 5.3kV

The ISP620-1X Optocoupler from ISOCOM COMPONENTS is a high-density, optically coupled isolator featuring a single-channel transistor output housed in a compact DIP package. This device consists of two infrared light-emitting diodes (LEDs) connected in inverse parallel, paired with a sensitive NPN silicon phototransistor, ensuring reliable signal isolation and transmission. It is engineered to facilitate safe communication between systems operating at different electrical potentials and impedances, making it a fundamental component for robust circuit design.

With a maximum forward current of 50mA and total power dissipation of 200mW, it balances performance with efficiency. The key specification is its high isolation voltage of 5.3kV, which provides critical protection against voltage surges and prevents ground loops, enhancing the safety and reliability of the overall system. A minimum current transfer ratio (CTR) of 50% ensures effective signal coupling.

Key Features & Applications

This optocoupler is ideal for a wide range of industrial and electronic applications. Its primary use is in industrial systems controllers, where it isolates sensitive logic circuits from noisy power stages. It is equally vital for signal transmission between circuits of differing voltage levels, protecting microcontrollers and other logic devices.

Common applications include interfacing in computers and computer peripherals, industrial automation systems, communications and networking equipment, and various signal processing circuits. Every unit undergoes 100% testing of all electrical parameters, guaranteeing consistent performance and reliability straight from the manufacturer.
