Surface Mount Optically Coupled Isolator
4N22U, 4N23U, 4N24U (COTS, TX, TXV)
4N47U, 4N48U, 4N49U (COTS, TX, TXV)
Description:
Each isolator in this series has a 890 nm (for the 4N2_U series) and 935nm (for the 4N4_ series) wavelength
infrared emitting diode and a NPN silicon phototransistor, which are mounted in a hermetically sealed Surface
Mount, 6 Pin package. Devices are designed for military and/or harsh environments. Burn-in condition is VCE =
10V, IF = 40mA, PD = 275 mW, TA = 25° C.
The 4N22U, 4N23U and 4N24 U (TX, TXV) devices are processed to MIL-PRF-19500/486. The 4N47 U, 4N48U
and 4N48U (TX, TXV) devices are processed to MIL-PRF-1 9500/548.
Please contact your local representative or OPTEK for more information.
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
RoHS
Applications:
• Military equipment
• High-Reliability environments
• High voltage isolation between
input and output
• Electrical isolation in dirty
environments
• Industrial equipment
• Medical equipment
• Office equipment
