60 V, 24 A N-channel in DPAK — STripFET™ II generation
The STD20NF06LT4 is a 60 V, 24 A N-channel power MOSFET from STMicroelectronics built on the STripFET™ II technology. It targets low-voltage DC-DC converters, load switches, and motor-drive half-bridges where conduction loss and switching speed both matter. The DPAK (TO-252) footprint keeps the board area tight while the 175°C junction rating lets it run hot in a cramped enclosure.
40 mOhm Rds(on) at 12 A — where the conduction loss lands
The on-resistance is specified at 40 mOhm maximum with 10 V on the gate and 12 A through the drain. That is the number to use when sizing the copper pour on the DPAK tab for a 24 A continuous load — at full current the dissipation hits about 23 W, and the 60 W package limit (Tc) leaves headroom if the heatsinking is adequate. The drive voltage range (5 V minimum for rated Rds(on)) means a 5 V logic gate drive will work, but the 10 V condition delivers the lowest resistance.
13 nC gate charge — fast switching without a heavy gate driver
With a total gate charge of 13 nC at 10 V, the STD20NF06LT4 switches cleanly from a modest gate-drive IC or even a push-pull from a PWM controller. The input capacitance sits at 660 pF at 25 V Vds, so the driver sees a light capacitive load. That combination keeps switching losses low in a 100–200 kHz converter and reduces the risk of gate-ringing on a long PCB trace.
STMicroelectronics lists the STD20NF06LT4 as Active.
