The 600 mOhm Rds(on) at 4.6 A and 10 V drive defines the conduction loss at full load.
Package and mounting — through-hole matters
The SPI07N65C3 comes in a TO-262-3 long-lead package (I²Pak), Infineon's PG-TO262-3-1 variant. Through-hole mounting means it goes into a PCB with the drain tab to sink heat into the board or an external heatsink.
Lifecycle and compliance — active and RoHS3
No last-time-buy notice, no end-of-life risk for current designs. The CoolMOS series has been around long enough that the process is mature, and Infineon typically supports these parts for years.
