4N49A

晶体管输出光电耦合器 Optocoupled Isolator

Description:

Each isolator in this series consists of an infraredemitting diode and a NPN silicon phototransistor, which are mounted in a hermetically sealed TO-78 package. Devices are designed for military and/or harsh environments. The suffix letter “A” denotes the collector is electrically isolated from the case.

The 4N22, 4N22A, 4N23, 4N23A,4N24, and 4N24A TX, TXVdevices are processed to MIL-PRF-19500/486.

The 4N47, 4N47A, 4N48, 4N48A, 4N49, and TX, TXV devices are processed to MIL-PRF-19500/548.

Features:

• TO-78 hermetically sealed package

• High current transfer ratio

• 1 kV electrical isolation

• Base contact provided for conventional transistor biasing

• TX and TXV devices processed to MIL-PRF-19500

• Patent No. 4124860
