Features:
Surface Mount (SM), Leadless Chip Carrier (LCC)
1 kV electrical isolation
Base contact provided for conventional transistor biasing
TX and TXV devices processed to MIL-PRF-19500
Description:
Each isolator in this series consists of an infrared emiꢀng diode and a NPN silicon phototransistor, which are mounted in a
hermeꢁcally sealed Surface Mount, 6 Pin package. Devices are designed for military and/or harsh environments.
The 4N22U, 4N23U and 4N24U (TX, TXV) devices are processed to MIL‐PRF‐19500/486. The 4N47U, 4N48U and 4N48U (TX,
TXV) devices are processed to MIL‐PRF‐19500/548.
