APT26F120B2 is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is MOSFET N-CH 1200V 27A T-MAX. Review the specifications below when checking this part for your BOM.
The APT26F120B2 is a single N-channel Power MOSFET from the POWER MOS 8™ family, manufactured by Microchip Technology. It utilizes T-MAX™ [B2] through-hole packaging (TO-247-3) and silicon technology. Key electrical parameters include a drain-source voltage of 1200 V, continuous drain current of 27 A, and maximum on-state resistance of 580 mΩ at 10 V gate drive. The device supports a power dissipation of 1135 W at case temperature, with an operating junction temperature range of -55°C to +150°C.
Verify the specific suffix B2 corresponds to the T-MAX package variant when sourcing. Confirm datasheet revisions match design requirements. Ensure thermal management solutions align with the 1135 W dissipation rating under intended operating conditions. Cross-reference pinouts with legacy components if replacing existing designs.
Select this component for applications demanding high voltage isolation and moderate current handling. The 580 mΩ resistance offers a balance between conduction loss and cost. Consider the through-hole mounting style for mechanical stability in industrial environments. Evaluate gate charge requirements against driver capabilities for optimal switching performance.
This device belongs to the POWER MOS 8™ series, representing an evolution in trench gate technology. It succeeds earlier generations like the APT series, offering improved ruggedness and switching speed. The T-MAX package provides superior thermal conductivity compared to standard TO-247 variants, facilitating higher power density in compact designs.
Direct substitutes may include other 1200V N-channel MOSFETs in TO-247-3 packages with comparable Rds(on) and current ratings. Verify pin compatibility and thermal resistance values before substitution.
