Product details

The IRL2203NL: It is a logic-level device, specified with a minimum drive voltage of 4.5V for the lowest Rds(on), making it suitable for 5V or 3.3V gate drive circuits common in battery-powered or low-voltage systems.

30V Vdss provides headroom for a 12V or 24V rail. 7mOhm Rds(on) at 10V gate drive and 60A.

The only available stock sits in independent distribution channels — surplus inventory, excess lots, or last-time-buy overruns. Independent distributors can quote this part against an RFQ with confirmed availability and current pricing at the time of inquiry.

Frequently asked questions

What is a good replacement for the IRL2203NL?

No official successor is listed by Infineon for the IRL2203NL. A replacement should match the 30V Vdss, 116A Id, 7mOhm Rds(on), and TO-262 package. Candidates in the same HEXFET family with similar ratings and package are the closest starting point, but verify pin compatibility and gate drive voltage requirements.

Can I use the IRL2203NL in a 12V circuit?

Yes, the 30V Vdss and logic-level gate drive (minimum 4.5V) make it well suited for 12V circuits. The 7mOhm Rds(on) at 10V gate drive keeps conduction losses low, and at 4.5V the on-resistance is still manageable for moderate currents.

Where can I buy the IRL2203NL?

Since the part is obsolete, it is available through independent semiconductor distributors who stock surplus and last-time-buy inventory. Independent distributors typically offer date-code and lot-traceability documentation for verification.
