Thermally-efficient MOSFET safely discharges capacitors on FPGA rails

Available now from Digi-Key, Diodes' DMN3027LFG 30V N-channel MOSFET is designed as a switch to rapidly and safely discharge large bulk capacitors used on FPGA power rails. The latest FPGAs found in telecoms equipment, servers, and data centres have multiple power rails that need to be correctly sequenced to safely power these systems up and down. Designers of high-reliability DC-DC power supplies can achieve this quickly and easily with the new MOSFET. To avoid damaging the FPGA system, each power rail needs to discharge before the next rail in the sequence is disabled. This is achieved by actively discharging the capacitors through the DMN3027LFG switch.
