Switching and drive considerations
Gate charge totals 66 nC at 10 V, so a gate driver sourcing 1 A can switch the FET in roughly 66 ns — fast enough for mid-frequency SMPS and motor pre-drive stages. Input capacitance is 860 pF at 25 V drain bias, which influences the driver's peak current requirement and the switching losses at higher frequencies. The gate threshold voltage is specified at 4 V maximum with 250 µA drain current, meaning a 5 V logic-level gate drive will not fully enhance the channel — the datasheet recommends 10 V drive to achieve the rated Rds(on).
Thermal and environmental reach
The 175°C maximum junction also provides headroom in high-current designs where self-heating pushes the die temperature well above the board ambient.
Package and footprint
Housed in the standard D-Pak (TO-252-3, DPAK) surface-mount package, the IRFR6215TRLPBF uses the exposed tab (drain) as the primary thermal path — the PCB copper area under the tab sets the junction-to-ambient thermal resistance. The 0.50 mm pitch leads are compatible with standard DPAK land patterns.
