The Fairchild Semiconductor FGA20S120M is a single N-channel Insulated Gate Bipolar Transistor (IGBT) designed for high-power switching applications. It features a maximum collector-emitter voltage of 1200 V and a continuous collector current rating of 40 A at 25 °C. The device is housed in a TO-3PN three-pin through-hole package, measuring 15.8 x 5 x 20.1 mm. It supports a maximum power dissipation of 348 W and operates within a temperature range of -55 °C to +175 °C junction temperature. The gate-emitter voltage is rated at ±25 V.
Verify the manufacturer origin carefully, as Fairchild Semiconductor's discrete semiconductor division was acquired by onsemi. Ensure the specific part number matches the required datasheet revision and that the component meets all necessary regulatory standards for your target market before finalizing procurement decisions.
Select this component when a 1200 V IGBT with 40 A capacity is required in a TO-3PN package. Confirm that the thermal management solution can handle the 348 W power dissipation rating. Verify compatibility with standard gate drive voltages of ±15 V to ±25 V for optimal switching performance.
This component belongs to the FGA20S series of IGBTs from Fairchild Semiconductor. The series typically includes variants with different voltage ratings, such as the FGA20S140P which offers 1400 V blocking capability. These devices are engineered for medium to high-power industrial applications requiring efficient switching and robust performance under high stress conditions.
The onsemi FGA20S140P is a related variant offering higher voltage tolerance (1400 V vs 1200 V) but similar current ratings. Verify pinout compatibility and thermal characteristics before substitution. Other 1200 V, 40 A IGBTs in TO-3PN packages may serve as alternatives if electrical parameters align.
