Handling Precautions for IGBTs
Operating Frequency Information
Insulated Gate Bipolar Transistors are susceptible to
gate-insulation damage by the electrostatic discharge of
energy through the devices. When handling these devices,
care should be exercised to assure that the static charge
built in the handler’s body capacitance is not discharged
through the device. With proper handling and application
procedures, however, IGBTs are currently being extensively
used in production by numerous equipment manufacturers in
military, industrial and consumer applications, with virtually
no damage problems due to electrostatic discharge. IGBTs
can be handled safely if the following basic precautions are
taken:
Operating frequency information for a typical device

performance for a specific application. Other typical
frequency vs collector current (I ) plots are possible using

6. Gate Termination - The gates of these devices are
essentially capacitors. Circuits that leave the gate
open-circuited or floating should be avoided. These
conditions can result in turn-on of the device due to
voltage buildup on the input capacitor due to leakage
currents or pickup.
