IRL100HS121 Description

Short technical summary and product information.

The Infineon IRL100HS121 is an N-channel MOSFET belonging to the OptiMOS™5 family, designed for higher power density and switching frequency applications. It offers a drain-source voltage (Vds) of 100V and a maximum on-resistance (RDS(on)) of 42mΩ at 10V gate-source voltage.

Key electrical characteristics include a typical gate charge (Qg tot) of 3.7nC and a gate threshold voltage (Vgs(th)) of 1.7V. The continuous drain current (ID) is rated at 11A at 25°C case temperature with a 10V gate-source voltage.

This MOSFET is housed in a compact PQFN 2mm x 2mm package, suitable for surface mounting. It is supplied on tape and reel with a standard quantity of 4000 units. The operating junction and storage temperature range is from -55°C to +175°C.

Target applications include wireless charging, adapters, and telecom power systems. Its design benefits include reduced parts count and the ability to be driven directly from microcontrollers.
