Heat generation/dissipation reduction
Aims to reduce heat generation and dissipation compared to SBD by utilizing MOSFET. Heat generation and dissipation are dependent upon externally connected Nch_MOSFET.
Wide input voltage range
Compatible with a wide range of input voltages from 4.5 to 65V, which allows for use in a wide range of devices.

Selectable reverse current protection function
The reverse current protection function can be switched ON and OFF via the REV terminal Hi/Lo status.
No function : Bidirectional conduction is possible.
