The TT Electronics 4N49U is a surface mount optically coupled isolator designed for military and high-reliability environments. Each isolator in this series comprises an infrared emitting diode and an NPN silicon phototransistor, housed in a hermetically sealed 6-pin surface mount package.
Key electrical specifications include 1 kV of isolation voltage and a maximum collector-emitter voltage of 35V. The device operates within a temperature range of -55°C to +125°C. It is suitable for applications requiring high voltage isolation between input and output, such as military equipment, industrial systems, and medical devices.
The 4N49U is designed for conventional transistor biasing with a provided base contact. Its surface mount (SM), leadless chip carrier (LCC) package facilitates integration into compact electronic assemblies. The device is processed to MIL-PRF-19500/548 standards for enhanced reliability in harsh conditions.
