The B511F-2 is a power module from the B-2 series designed for AC or DC variable voltage output applications up to 15 kW. It features a maximum DC output current of 25 A at Tc = 85°C with a maximum voltage drop of 1.65 V at peak current, and operates over a junction temperature range of -40°C to 125°C. The module includes a free-wheeling diode and supports AC line input voltages of 120 VAC (400 V RMS), 240 VAC (600 V RMS), and 280 VAC (800 V RMS), with a maximum non-repetitive surge current of 250 A. The B511F-2 is UL recognized (E72445) and provides excellent thermal management with a junction-to-ceramic base thermal resistance of 0.9°C/W, making it suitable for industrial power control, variable speed drives, and heating applications requiring reliable switching performance.
