IRF1104L is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Infineon Technologies. Its product description is MOSFET N-CH 40V 100A TO262. Review the specifications below when checking this part for your BOM.
The IRF1104L is a discontinued N-channel power MOSFET from Infineon Technologies, part of the HEXFET series. It features a 40V drain-source voltage rating and a continuous drain current of 100A at case temperature. The device utilizes a TO-262 through-hole package with a maximum on-resistance of 9 milliohms at 10V gate drive. Key electrical parameters include a gate charge of 93 nC and an input capacitance of 2900 pF. Power dissipation reaches 170W at case temperature, supporting operation across a junction temperature range of -55°C to 175°C.
Verify component authenticity carefully as this item is officially discontinued. Confirm manufacturing date codes against project timelines due to potential supply chain limitations. Ensure replacement strategies are in place if long-term availability is required for new designs. Cross-reference datasheet revisions to match specific lot requirements.
Select this component only when legacy compatibility or specific through-hole form factors are mandatory. Evaluate thermal management capabilities given the 170W case dissipation limit. Compare against modern surface-mount alternatives for improved efficiency and space utilization in new product developments.
This device belongs to Infineon's established HEXFET portfolio, representing earlier generations of planar MOSFET technology. It serves as a predecessor to newer OptiMOS and StrongIRFET lines, offering reliable performance for industrial applications where high current density in traditional packages remains necessary.
Consider the IRF1104 for similar pin-compatible needs, though it also carries discontinuation status. For active alternatives, evaluate the IRF1404Z which offers higher current ratings in comparable packages.
