BSP125 E6433 is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Infineon Technologies. Its product description is MOSFET N-CH 600V 120MA SOT223-4. Review the specifications below when checking this part for your BOM.
The BSP125 E6433 is an N-channel power MOSFET from Infineon Technologies, part of the OptiMOS 5 family. It features a 600V drain-source voltage rating and a continuous drain current of 120mA. The device utilizes advanced vertical DMOS technology for high-efficiency switching. It is housed in a SOT-223 (TO-261-4) surface-mount package. Key electrical parameters include a maximum power dissipation of 1W and a typical on-resistance optimized for low-loss operation. The component is designed for robust performance in various power management applications.
Verify the specific suffix E6433 to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status as historical data may vary. Check lifecycle status as some listings indicate obsolete or end-of-life conditions. Ensure compatibility with standard SOT-223 footprints during integration.
Select this component when a 600V blocking voltage is required with low gate charge characteristics. The 120mA current rating suits light-load switching applications. Consider thermal management due to the small package size. Compare against newer OptiMOS generations if higher current density is needed.
This part belongs to Infineon's OptiMOS 5 series, which represents a generation of power MOSFETs designed for improved figure-of-merit. The series targets applications requiring efficient high-voltage switching with minimal conduction losses. The BSP125 variant specifically addresses niche requirements for moderate current at high voltage levels.
Direct substitutes may include other 600V N-channel MOSFETs in SOT-223 packages from compatible manufacturers. Verify pinout compatibility and thermal resistance values before substitution. Newer OptiMOS iterations might offer enhanced performance but require design review.
