The B512FS-2 is a power module designed for AC/DC variable voltage output control with a maximum DC output current of 25 A at 85°C junction temperature. It features a maximum voltage drop of 1.65 V at 25 A peak current, an operating junction temperature range of -40°C to 125°C, and supports 240 VAC input (600 VRMS). The module includes a free-wheeling diode and external suppressor, with an isolation voltage rating of 2500 Vrms and a maximum thermal resistance of 0.9°C/W from junction to ceramic base. The B512FS-2 is ideal for industrial power control applications requiring reliable switching performance, with a maximum non-repetitive surge current of 250 A and an I²t rating of 260 A²sec for fusing protection.
