Product details

The 26.5 mOhm maximum on-resistance at 22 A with 10 V gate drive sets the conduction loss baseline for a 48 V or 72 V bus design. Total gate charge of 63 nC at 10 V means a standard gate-driver IC can switch it in the tens-of-kilohertz range without excessive drive current.

The gate threshold voltage maximum of 4 V at 250 µA means a 5 V logic-level gate drive will turn it on, but the Rds(on) will be significantly higher than the 10 V figure — the drive voltage for minimum Rds(on) is 10 V. For a 12 V gate drive rail the 63 nC gate charge is manageable with a standard totem-pole driver; at higher switching frequencies the input capacitance of 1770 pF at 25 V drain-source becomes the dominant switching loss term.

Frequently asked questions

Is IRF540ZSPBF a direct replacement for IRF540N?

The IRF540ZSPBF is a different variant within the same HEXFET family. The IRF540N is typically a through-hole TO-220 device, while the IRF540ZSPBF is a surface-mount D2PAK. Electrical ratings differ — verify the 100 V Vdss, 36 A Id, and 26.5 mOhm Rds(on) against your IRF540N BOM requirements before substituting. Pin compatibility is not guaranteed across package types.
