Working Principle

The IRG4BC20FD-STRL is a half-controlled, "ON/OFF" type of transistor with an integrated Soft Recovery Diode (SRD). The IRG4BC20FD-STRL works by controlling the voltage across the IGBT base-emitter junction. At low gate drive voltages, the device will remain off and the SRD will remain in its "blocking" state, leaving the IGBT disabled. When the gate voltage is increased to a certain level, the base-emitter voltage will increase to the point where the IGBT junction turns on, allowing current to flow through the device. At this point, the SRD becomes active, allowing the IGBT to switch off quickly when the gate voltage is decreased. This fast switching with low gate drive voltages makes the IRG4BC20FD-STRL efficient and ideal for high speed applications.

Conclusion

In conclusion, the IRG4BC20FD-STRL is a fast IGBT with Soft Recovery Diode (SRD) integrated into the same package. It is a single-chip solution with a small size and fast switching capabilities that make it suitable for a variety of applications including electric vehicle inverters and power supplies, uninterruptible power supplies (UPS), and solar inverters.
