Product details

100 V, 33 A N-channel — what this part was designed for

The TO-262 (I²Pak) through-hole package with long leads suits designs that need a secure mechanical mount to a heatsink or PCB.

For a production line, this means no factory orders are accepted; the only available stock is surplus or excess inventory held by independent distributors. Any BOM using this part should plan for a replacement, either a direct pin-compatible alternative or a functionally equivalent device in the same TO-262 footprint.

Key ratings and their design impact

Gate charge of 71 nC at 10 V is moderate — a standard gate driver can switch it without excessive drive loss.

Because the IRF540NLPBF is obsolete, new-stock procurement runs through independent distribution channels. We source it against an RFQ from our network of vetted excess-stock holders. For dual-sourcing or a long-term production fix, a pin-compatible replacement should be qualified.

Frequently asked questions

Where can I buy IRF540NLPBF and get a price?

The IRF540NLPBF is obsolete, so it is not available through factory-authorized channels. Submit an RFQ for current availability and pricing — we confirm both at quote time.

Is IRF540NLPBF obsolete?

Yes, Infineon lists the IRF540NLPBF as obsolete. No factory orders are accepted; supply is limited to surplus or excess inventory.

What is the replacement for IRF540NLPBF?

Infineon does not publish an official successor order code for the IRF540NLPBF. A functionally equivalent replacement should match the 100 V Vdss, 33 A Id, 44 mΩ Rds(on) at 10 V, and the TO-262 (I²Pak) through-hole footprint. The IRF540N (non-leaded variant) shares the same die but differs in package lead form — verify pin compatibility before substitution.
