Product details

Gate drive and switching — what 20 nC gate charge means for your driver

The IRL520NPBF: Gate charge is 20 nC at 5V Vgs. That is moderate — a typical MCU GPIO sourcing a few milliamps will take microseconds to charge the gate, so for PWM above a few kHz you will want a dedicated gate driver. The input capacitance is 440 pF at 25V Vds, which helps keep the Miller plateau manageable. The ±16V maximum gate-source rating gives headroom for gate-drive overshoot, but stay within the 4V to 10V drive range the datasheet specifies for achieving the rated Rds(on).

Frequently asked questions

What is the Rds(on) of the IRL520NPBF at 10V Vgs?

Maximum on-resistance is 180 milliohms at 6A drain current with 10V gate-source drive.

Can the IRL520NPBF replace the IRF520 in a 100V circuit?

Both are 100V N-channel TO-220AB MOSFETs, but the IRL520NPBF has a lower gate threshold (2V max vs higher for the IRF520), making it logic-level compatible. Check the pinout — both use the standard TO-220 pin arrangement — and verify that the 180mOhm Rds(on) and 10A rating meet your load requirements. The IRF520 typically has higher Rds(on) and requires a higher gate drive voltage.
