The IXGT20N120BD1 is a single N-channel Insulated Gate Bipolar Transistor (IGBT) manufactured by IXYS. It features a 1200 V collector-emitter breakdown voltage and a continuous collector current of 20 A at 25°C. The device utilizes a TO-268AA surface-mount package, also known as D3PAK, with two leads plus a tab. Key electrical characteristics include a maximum gate-emitter voltage of ±20 V and an operating junction temperature range from -55°C to +150°C. The component incorporates an integrated anti-parallel fast recovery diode.
Verify the specific suffix BD1 against the manufacturer's datasheet to confirm the presence of the integrated diode and exact pinout configuration. Ensure the procurement source provides original manufacturer documentation to validate authenticity. Confirm that the TO-268AA package dimensions match the target PCB footprint requirements before finalizing orders.
Select this component when a high-voltage IGBT with an integrated freewheeling diode is required in a surface-mount form factor. The 1200 V rating suits applications exceeding standard 600 V or 650 V limits. Evaluate the thermal resistance of the TO-268AA package against the expected power dissipation to determine adequate heatsinking needs for the specific operating conditions.
This device belongs to the IXGT series of high-voltage IGBTs produced by IXYS. The series is designed for general-purpose power switching applications requiring reliable performance under high voltage stress. The integration of the diode distinguishes it from standard single IGBTs, offering a compact solution for half-bridge configurations.
Direct substitutes may include other IXYS IGBTs in the TO-268AA package with matching 1200 V ratings and integrated diodes. Cross-brand replacements require verification of pin compatibility, thermal characteristics, and electrical parameters such as saturation voltage and switching times.
