Gate charge totals 32 nC at 10 V, which sets the driver current needed for the target switching frequency: a 32 nC gate switched at 100 kHz draws 3.2 mA average from the driver, well within the capability of most standard MOSFET gate-drive ICs. ## Package and thermal: TO-220FP full-pack isolation The supplier device code is TO-220FP.
