Product details

It is designed for high-current switching applications where low on-resistance and logic-level gate drive are required — typical uses include DC-DC converters, motor drives, battery management, and power supply output stages. The 30 V drain-to-source voltage rating and 116 A continuous drain current make it suitable for 12 V and 24 V bus systems in industrial and automotive environments.

Gate charge of 60 nC at 4.5 V is moderate — a typical gate driver with 1 A peak current can switch this MOSFET in about 60 ns, which is adequate for switching frequencies up to a few hundred kHz. Input capacitance of 3290 pF at 25 V Vds is a consideration for the driver's drive strength and switching losses at higher frequencies.

This means Infineon has discontinued production and no further factory orders are accepted.

Frequently asked questions

Is IRL2203NPBF obsolete?

Yes, the IRL2203NPBF is officially obsolete per Infineon's lifecycle status. No further factory production is planned.

What is the Rds(on) of IRL2203NPBF?

At 4.5 V gate drive the on-resistance will be higher — the datasheet typical curve should be consulted for the exact value at your operating point.
