Device identity and switching performance
The SM74101SD/NOPB: It delivers a peak output current of 3 A source and 7 A sink, which directly determines how fast the gate capacitance charges and discharges — the 14 ns rise and 12 ns fall times (typical) keep switching losses low in a 500 kHz to 2 MHz DC-DC converter stage.
Package and thermal interface
Housed in a 6-WDFN with exposed pad (supplier package 6-WSON 3x3 mm), the part relies on the pad soldered to a copper plane for thermal dissipation.
