Specifications

The IRGIB4620DPBF features a collector-emitter voltage (VCE) of 600V, a continuous collector current (IC) of approximately 20A (depending on temperature and application conditions), and a gate-emitter voltage (VGE) of ±20V. It has a typical turn-on and turn-off time in the range of tens of nanoseconds, making it suitable for high-frequency applications. The operating junction temperature ranges from -55°C to +150°C. The device is typically packaged in a TO-220 or similar through-hole package. The gate charge is very low, contributing to faster switching. The device is also short circuit rated, enhancing robustness in demanding applications.

The low VCE(on) characteristic of the IRGIB4620DPBF minimizes conduction losses, particularly important in high-current applications. The fast switching speed reduces switching losses and allows for higher operating frequencies, improving overall system efficiency and reducing the size of passive components. Its rugged design and short circuit rating further enhances its suitability for industrial and power electronics applications. Because of its low gate charge it can be driven directly from a microcontroller without requiring an external gate driver in some applications.
