Input capacitance is 4610 pF at 25 V Vds. ## Temperature grade and application envelope The gate threshold voltage maximum is 3.9 V at 100 µA drain current. With a 6 V to 10 V drive range for minimum Rds(on), a 5 V logic-level gate signal will not fully enhance the channel — you need a 10 V rail or a dedicated gate-driver IC to hit the 2.4 mOhm spec.","metaTitle":"IRFR7440TRPBF N-Channel MOSFET, 40 V, 90 A, 2.4 mOhm Rds(on)","metaDescription":"IRFR7440TRPBF N-Channel HEXFET MOSFET, 40 V Vdss, 90 A continuous drain, 2.4 mOhm Rds(on) at 10 V.
