According to information, Diodes corp. has released ZXGD3006E6 gate driver which is specially designed for switching high power IGBT to improve the power conversion efficiency of solar inverter, motor drive and power supply applications.

When the input current is 1mA, the gate drive typically provides 4A drive current, making it is an ideal option for controller’s high output impedance and high-gain buffer stage between low input impedance of IGBT. ZXGD3006E6 configures an emitter follower to prevent latch-up and shoot-through, to achieve the purpose of transmission delay time of less than 10ns.

The operating range of ZXGD3006E6 covers 40V to improve the switching components all around, thus to reduce the conduction loss to a minimum. The device is allowed gate drive from +20 V to-18V to prevent IGBT false triggers caused by dV / dt.

The gate driver provides independent power supply and sink output, which can start up and close the component respectively, so that circuit designers can better set the switch application-specific functionality. In addition, the circuit has 10Amp peak current handling capability, which enable the device to control charge and discharge of gate pole capacitive loads to reduce EMI (electromagnetic interference) problems and the risk of cross-conduction as under higher frequency operation.

The gate drive uses rugged SOT26 package, and provides more competitive devices with higher pulse current to ensure the reduction of heat dissipation, therefore, to improve product reliability. In addition, the new device package pin is optimized to simplify printed circuit board layout and reduce parasitic lead inductance.
