Gate charge totals 48 nC at 5 V, so a driver sourcing 1 A can switch the gate in under 50 ns, though the actual switching loss depends on the gate drive loop inductance and the external series resistor. ## Thermal and package considerations Input capacitance is 1700 pF at 25 V drain-source, which together with the gate charge sets the switching speed limit when driven from a high-impedance source. This means the part is still available for existing production but is not intended for new board spins. It is ROHS3 compliant.","metaTitle":"Infineon IRLZ44NSTRLPBF HEXFET N-Ch 55V 47A D2PAK","metaDescription":"Infineon IRLZ44NSTRLPBF N-channel HEXFET MOSFET, 55V, 47A, 22mOhm Rds(on), D2PAK.
