APT10045JLL is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is MOSFET N-CH 1000V 21A ISOTOP. Review the specifications below when checking this part for your BOM.
The APT10045JLL is a single N-channel Power MOSFET module from the POWER MOS 7 ISOTOP family, manufactured by Microchip Technology. It utilizes silicon technology and features an SOT-227-4 (miniBLOC) package designed for screw mount installation. Key electrical specifications include a drain-source breakdown voltage of 1 kV, a continuous drain current of 21 A, and a maximum on-resistance of 450 mOhms at 10 V gate drive. The device supports a gate-source voltage range of ±30 V with a threshold voltage of 3 V. It offers a power dissipation capacity of 460 W and operates within a junction temperature range of -55°C to +150°C.
Verify the specific suffix JLL against official Microchip documentation to confirm pinout compatibility and thermal characteristics. Ensure that the ordering information matches the exact datasheet revision required for your design. Cross-reference the SOT-227-4 footprint dimensions with your PCB layout guidelines. Confirm RoHS compliance status through the manufacturer's current product status page before finalizing procurement.
Select this component when designing circuits requiring a 1 kV rating with moderate current handling capabilities around 21 A. The 450 mOhm on-resistance makes it suitable for applications prioritizing efficiency over extreme current density. Consider the ISOTOP package for simplified thermal management compared to standard TO-247 variants. Evaluate the 460 W power dissipation limit against your system's cooling strategy and ambient operating conditions.
This part belongs to the APT100 series of discrete power modules, which are engineered for industrial and commercial power conversion. The ISOTOP packaging distinguishes these devices by integrating the drain terminal directly with the insulating base, facilitating efficient heat transfer to external cooling structures while maintaining electrical safety.
Consult Microchip's official cross-reference guides for verified substitutes. Potential alternatives may include other APT100 series variants with different Rds(on) ratings or voltage classes, provided they maintain compatible pinouts and thermal profiles.
