IRF40H233XTMA1 is listed in the FET, MOSFET Arrays range at ChipApex. The manufacturer field lists Infineon Technologies. Its product description is MOSFET 2N-CH 40V 8TDSON. Review the specifications below when checking this part for your BOM.
The IRF40H233XTMA1 is a dual N-channel StrongIRFET power MOSFET housed in a SuperSO8 5x6 surface-mount package. It features a maximum drain-source voltage of 40 V and a continuous drain current of 35 A at 25°C case temperature. The device exhibits a maximum on-resistance of 6.2 mΩ at 10 V gate drive, with typical gate charges of 16 nC for Qgd and 35 nC for Qg. Thermal performance includes a junction-to-case resistance of 45 K/W and a maximum operating junction temperature of 175 °C.
Verify the specific ordering suffix XTMA1 to confirm tape-and-reel packaging quantities and handling specifications. Ensure compatibility with standard SMD reflow soldering profiles for the SuperSO8 footprint. Cross-reference official Infineon documentation for RoHS compliance status and recommended storage conditions prior to assembly.
Select this component for applications requiring compact dual-channel integration with moderate voltage ratings. Evaluate the 6.2 mΩ on-resistance against system conduction loss requirements. Confirm that the 45 K/W thermal resistance aligns with the available heatsinking or PCB copper area constraints for the intended duty cycle.
This part belongs to Infineon's StrongIRFET family, designed to balance switching speed and conduction efficiency. The SuperSO8 package provides a small form factor suitable for dense PCB layouts. It serves as an alternative to discrete dual MOSFET solutions, reducing board space and parasitic inductance in synchronous applications.
Consult official cross-reference tools for verified substitutes. Ensure any replacement matches the 40 V rating, SuperSO8 5x6 footprint, and comparable RDS(on) and thermal characteristics.
