Switching and drive characteristics
The STL210N4F7AG: Total gate charge is 43 nC at 10 V, and input capacitance measures 3600 pF at 25 V drain-source — numbers that define the gate-driver current needed to hit a target switching frequency without excessive crossover loss. The 4 V maximum gate threshold at 250 µA drain current means the device turns on cleanly with standard 5 V or 10 V gate drive logic; the ±20 V Vgs max gives headroom for drive transients in noisy automotive rails.
Package and assembly considerations
Housed in an 8-lead PowerVDFN with a PowerFlat 5x6 mm footprint, this is a surface-mount part with an exposed pad on the bottom that carries the drain current and conducts heat to the board.
