The IRG4BC20K is a standard input single IGBT manufactured by Infineon Technologies, housed in a TO-220AB through-hole package. It features a maximum collector-emitter voltage of 600 V and a continuous collector current of 15 A at 25°C. The device has a typical saturation voltage of 2.3 V at 9 A with a 15 V gate drive. Key switching parameters include a turn-on delay time of 43 ns, a fall time of 240 ns, and a reverse recovery time of 37 ns for the integrated anti-parallel diode. Gate charge is specified at 27 nC, and the maximum power dissipation is 60 W.
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status as older revisions may differ from current standards. Ensure thermal management solutions match the 60 W dissipation rating under expected ambient conditions. Validate that the TO-220AB package fits the target PCB footprint and mounting constraints before finalizing procurement.
Select this component when a balance between moderate current handling and fast switching speed is required in compact designs. It serves as a suitable replacement for legacy parts in existing circuits requiring 600V blocking capability. Consider the 2.3 V saturation voltage for efficiency calculations in low-to-medium power applications where thermal resistance is manageable without excessive heatsinking.
This part belongs to Infineon's BC series of IGBTs, which are engineered for general-purpose power switching applications. The series emphasizes cost-effectiveness and ease of integration into standard industrial and consumer electronics designs. It complements other discrete power devices within the manufacturer's portfolio for complete power stage implementation.
