Product details

The device is packaged in a TO-262 through-hole package (I²Pak) with long leads, intended for board-level mounting where a robust thermal connection to the PCB or heatsink is required.

This wide range suits applications exposed to severe thermal cycling, such as automotive under-hood or industrial motor drives, though the obsolete status means new designs should not rely on this specific part number.

Lifecycle status and what it means

The IRL2203NLPBF is listed as obsolete. Buyers should plan for last-time-buy or surplus-channel procurement.

The maximum gate charge is 60 nC at 4.5 V gate-source, which influences the switching speed and gate-driver sizing. Input capacitance is 3290 pF at 25 V drain-source, a parameter to consider when estimating switching losses in high-frequency converters.

Frequently asked questions

What is the replacement for IRL2203NLPBF?

No official replacement part number is documented for the IRL2203NLPBF. A functionally equivalent N-channel MOSFET in the same TO-262 package with a 30 V Vdss rating and similar Rds(on) would need to be selected based on the specific current and switching requirements of the application.

Where to buy IRL2203NLPBF?

The IRL2203NLPBF is obsolete and not stocked in standard distribution. It can be sourced through independent and surplus distributors; availability and pricing are confirmed upon request via an RFQ.
