The 1300 pF input capacitance at 25 V drain bias is moderate — the gate drive sees a capacitive load that rises with Vds, so the driver's peak current must be sized for the full Ciss at the operating voltage. The 4 V threshold at 250 µA is a typical hard-switching turn-on point; the 10 V drive voltage for minimum Rds(on) is standard for logic-level gate drives that can source 10 V.","metaTitle":"IRFR1205TRPBF N-Channel MOSFET, 55V 44A DPAK","metaDescription":"IRFR1205TRPBF HEXFET N-channel MOSFET, 55V Vdss, 44A continuous drain, 27mOhm Rds(on) at 10V.
