About this product
Fairchild G20N60B3D is a 600 V, 40 A IGBT with an anti-parallel hyperfast diode built in. It is used in switching stages of motor drives, inverters and induction heating, where the diode provides a freewheeling path for inductive loads. A suitable gate driver is required.

Frequently asked questions
What gate drive does the G20N60B3D need?
An IGBT is voltage-driven and is normally switched with a gate-emitter voltage of around 15 V through a gate driver. Do not exceed the maximum gate-emitter voltage listed in the datasheet.
Why is the built-in diode important?
The anti-parallel hyperfast diode gives inductive loads a path for current when the IGBT turns off, protecting the device from voltage spikes in motor and inverter circuits.
