The input capacitance is 450 pF at 50 V drain bias, so the gate-drive loop inductance and the driver's peak current capability set the turn-on and turn-off edge rates. The gate-source threshold voltage is 4.5 V maximum at 50 µA drain current, meaning a 10 V drive rail is needed to achieve the rated Rds(on); a 5 V logic-level gate drive will not fully enhance the channel. ## Package and mounting — DPAK thermal interface The TO-252-3 (DPAK) surface-mount package has a drain tab that is the primary thermal path.","metaTitle":"STD4N62K3 N-Channel MOSFET, 620 V, 3.8 A, DPAK","metaDescription":"STD4N62K3 N-channel 620 V 3.8 A MOSFET in DPAK.
