55V, 30A N-channel in D2PAK
The IRLZ34NSTRLPBF: The 35 mOhm maximum on-resistance is specified at 16 A with a 10 V gate drive, and the device is also characterized for logic-level drive at 4 V. The D2PAK (TO-263) surface-mount package suits automated assembly on power supply and motor control boards where the backside tab is soldered to a copper island for thermal management. The 68 W power dissipation at the case (Tc) versus 3.8 W at ambient (Ta) means the heatsinking on the PCB pad determines the real-world current capability.
Total gate charge is 25 nC at a 5 V gate drive, and the input capacitance measures 880 pF at 25 V drain-source. These numbers set the switching speed ceiling: a gate driver sourcing 1 A charges the gate in roughly 25 ns, but the practical edge rate also depends on the gate loop inductance and the Miller plateau duration.
