4N30** is an optocoupler (optoisolator) manufactured by **MOTO/qtc** (Motorola/Quality Technology Corporation).

The 4N30 is an optocoupler (optoisolator) manufactured by MOTO/qtc (Motorola/Quality Technology Corporation). Below are its key specifications, descriptions, and features:

Specifications:

  • Isolation Voltage: 5,300V (peak)
  • Collector-Emitter Voltage (VCEO): 30V
  • Current Transfer Ratio (CTR): 20% (min) at 10mA forward current
  • Forward Current (IF): 60mA (max)
  • Rise/Fall Time: 2μs (typical)
  • Operating Temperature Range: -55°C to +100°C
  • Package Type: 6-pin DIP (Dual In-line Package)

Description:

The 4N30 is a phototransistor optocoupler that provides electrical isolation between input and output circuits. It consists of an infrared LED optically coupled to a phototransistor, ensuring signal transmission without direct electrical connection.

Features:

  • High Isolation Voltage (5.3kV) for safety in high-voltage applications.
  • Fast Switching Speed (2μs rise/fall time) for digital signal isolation.
  • Wide Operating Temperature Range (-55°C to +100°C) for industrial use.
  • Compact 6-pin DIP package for easy PCB mounting.
  • Reliable Signal Isolation for noise immunity in industrial and automotive systems.

This optocoupler is commonly used in power supply feedback circuits, digital logic isolation, and industrial control systems.
