30V MOSFET from Diodes Incorporated Enables Rapid and Safe Discharge of Bulk Capacitors on FPGA Power Rails

Business Wire
Diodes Incorporated (Nasdaq: DIOD), a leading global
manufacturer and supplier of high-quality application specific
standard products within the broad discrete, logic and analog
semiconductor markets, today introduced the DMN3027LFG 30V
N-channel MOSFET. This device 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 centers 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 this new MOSFET from Diodes.
The DMN3027LFG has an RDS(on) of 26mΩ at 4.5V, which is low
enough to discharge a 15mF capacitor in <10ms but not so low
that sharply rising current peaks could cause EMI issues or give
rise to transient thermal stresses, potentially damaging the MOSFET
or capacitor bank. Under the typical FPGA low-voltage rail
conditions of 1V, this current is self-limited by the MOSFET
channel resistance as specified in the safe operating area (SOA).
This SOA is given at a +60°C ambient temperature with minimal
heat-sinking to support the typical application conditions,
allowing peak currents up to 20A to be safely handled in
<10ms.
The DMN3027LFG is offered in a PowerDI®3333 package, which has a
low thermal resistance from junction to exposed pad of <10°C/W
enabling the dissipation of up to 3W. For further information,
