The RFIS70N06SM is a power field-effect transistor manufactured by Harris Corporation. It is an N-channel silicon metal-oxide semiconductor FET housed in a TO-263AB package. The device features a minimum drain-source breakdown voltage of 60V and supports a maximum continuous drain current of 70A. Its maximum on-resistance is specified at 0.014 ohms, with an avalanche energy rating of 19 mJ.
Verify the manufacturer designation as Harris Corporation against current corporate records, noting historical acquisitions. Confirm the specific suffix 'S' indicates the correct package variant and pinout compatibility for your PCB footprint. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards, as older Harris parts may not.
Select this component when a 60V rating and high current capacity near 70A are required. The low on-resistance minimizes conduction losses in power paths. Verify that the thermal management solution can handle the dissipation associated with the specified current levels in the TO-263AB package.
This part belongs to the RF1S series of power MOSFETs from Harris Corporation. The series covers various voltage and current ratings within the TO-263AB form factor. This specific model targets applications needing robust performance at 60V with minimal resistive loss.
