Power MOSFET Optocoupler Radiation Tolerant, ± 90V - 0.8A

Power MOSFET Optocoupler Radiation Tolerant, ± 90V - 0.8A
The 53124 is a single channel power MOSFET optocoupler which is suitable as a pin for pin replacement for the Mii 53111 when radiation tolerant performance and similar electrical performance to the 53111 is required. The primary difference between the 53124 and 53111 is that the radiation tolerant power MOSFETs employed in the 53124 exhibit a higher RDS(ON). The higher values of RDS(ON) results in a lower current for the same power dissipation or higher power dissipation for the same current levels relative to the 53111.
