Hi-Reliability Optically Coupled Isolator
4N22, 4N23, 4N24 [A] (COTS, TX, TXV)
4N47, 4N48, 4N49 [A] (COTS, TX, TXV)
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
Applications:
• High-voltage isolation
between input and output
• Electrical isolation in dirty
environments
• Industrial equipment
• Medical equipment
• Office equipment
Description:
Each isolator in this series has a 890 nm (for the 4N2_ series) and 935nm (for the 4N4_ series) wavelength
infrared emitting 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. Burn-in condition is VCE = 10V, IF = 40mA,
PD = 275 mW, TA = 25° C. The suffix letter “A” denotes the collector is electrically isolated from the case.
The 4N22, 4N22A, 4N23, 4N23A,4N24, and 4N24A (TX, TXV) devices are processed to MIL-PRF-19500/486.
The 4N47, 4N47A, 4N48, 4N48A, 4N49, and 4N49A (TX, TXV) devices are processed to MIL-PRF-19500/548.
