With a gate charge of 22.7 nC at 10 V, the drive power requirement is modest — a simple PWM controller's totem-pole output can drive it directly at switching frequencies up to 100 kHz without excessive gate-drive loss. ## Thermal and switching headroom The part is ROHS3 compliant.","metaTitle":"STP3NK90Z N-Channel MOSFET, 900 V, 3 A, TO-220-3","metaDescription":"STP3NK90Z N-channel 900 V 3 A MOSFET in TO-220-3.
