FGL40N120ANDTU

Overview

The FGL40N120ANDTU is a single N-channel IGBT from onsemi, housed in a TO-264-3 (TO-264AA) package. It features a maximum collector-emitter voltage of 1200 V and a continuous collector current of 40 A at 25°C, with a pulsed current rating of 80 A. The device exhibits a typical saturation voltage of 2.9 V at 40 A and 15 V gate drive. Switching characteristics include a turn-on delay of 45 ns and a turn-off delay of 560 ns under test conditions of 600 V, 40 A, and a 23 Ω gate resistor. Total power dissipation is rated at 391 W, with an operating junction temperature range spanning -55°C to 150°C.

Feature Summary

• Combines MOSFET input characteristics with bipolar transistor conduction for efficient high-power switching.
• Utilizes Trench Field Stop technology to optimize the trade-off between low saturation voltage and fast switching speeds.
• Designed for robust performance in hard-switching applications with high thermal stability.

Applications

• Industrial motor drives and inverters
• High-frequency welding equipment
• Uninterruptible power supplies (UPS)
• Induction heating systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure that the TO-264-3 footprint matches the target PCB design. Cross-reference the part number with official onsemi distributors to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high voltage blocking capability combined with moderate current handling. Evaluate the thermal resistance requirements based on the 391 W power dissipation limit. Consider the gate charge and switching energy values when designing the driver circuit to ensure optimal efficiency and minimize switching losses in the target system.

Part Context

This device belongs to onsemi's discrete IGBT portfolio, specifically utilizing Trench Field Stop architecture. It serves as a replacement or upgrade for older generation IGBTs in power conversion circuits. The TO-264-3 package provides a balance between thermal performance and mounting simplicity for through-hole assembly in industrial power electronics.

Replacement Considerations

Direct substitutes may include other 1200V 40A IGBTs in TO-264 packages from onsemi or competitors, provided pinouts and electrical parameters align. Verify equivalent switching speeds and saturation voltages to maintain system performance. Always consult the latest mechanical drawings for any potential dimensional differences.
