The APT35GP120BG is a single Insulated Gate Bipolar Transistor (IGBT) manufactured by Microchip Technology. It utilizes Silicon technology and is housed in a TO-247-3 through-hole package. The device features a collector-emitter maximum voltage (VCEO) of 1.2 kV and a collector-emitter saturation voltage of 3.3 V. It supports a continuous collector current of 96 A at 25°C, with a power dissipation rating of 543 W. The gate-emitter maximum voltage range is -20 V to +20 V. Operating temperatures span from -55°C to +150°C.
Verify the specific ordering suffix against the official Microchip datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides authentic components with traceable documentation. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity before purchase.
Select this component when a single-switch topology requires 1200 V blocking capability and high current handling. Evaluate the thermal management requirements based on the 543 W power dissipation rating and the TO-247-3 package thermal resistance. Confirm that the gate drive voltage limits align with the -20 V to +20 V specification for reliable operation.
This component belongs to the Microchip PowerTrench IGBT family, designed for general-purpose power switching. It serves as a discrete alternative to integrated modules in applications where space allows for individual component placement. The TO-247-3 package offers a balance between thermal performance and ease of integration into standard PCB layouts.
Direct replacements must match the 1200 V rating, similar current capacity, and TO-247-3 footprint. Verify that any substitute maintains comparable saturation voltage and switching characteristics to ensure circuit performance consistency.
