Product details

Gate charge and switching speed

Total gate charge is 220 nC at 10 V, with an input capacitance of 9400 pF at 50 V drain-source. That Qg number tells the gate-driver designer the energy per switching cycle — at 20 kHz switching, the average gate current is 4.4 mA, easily handled by a standard driver, but the peak current during the Miller plateau determines the rise time and the cross-conduction window.

Through-hole TO-220AB — thermal and mechanical fit

The TO-220AB package with through-hole mounting suits designs where the PCB is the primary heatsink or where a clip-on heatsink is acceptable.

Frequently asked questions

What is the Rds(on) of IRFB3077PBF?

The maximum on-resistance is 3.3 mOhm at 75 A drain current with 10 V gate drive. This is the worst-case value at 25°C junction temperature; actual Rds(on) increases with temperature per the normalised curve in the datasheet.

What is the gate charge of IRFB3077PBF?

Total gate charge is 220 nC at 10 V gate voltage. This value determines the gate-driver current requirement and switching losses at the target frequency.

Can IRFB3077PBF be used for motor control?

Yes — the 75 V drain-source rating and 120 A continuous current capability, combined with the 3.3 mOhm Rds(on), make it suitable for DC brush and brushless motor drives up to 48 V nominal bus voltage, provided the switching frequency and gate-drive design account for the 220 nC gate charge.
