International Rectifier has introduced IRFH4257D FastIRFET dual power MOSFET housed in a high performance 4x5 PQFN power block package. The package option expands the power block family's capability to lower power for compact designs in 12V input DC-DC synchronous buck applications including advanced telecom and netcom equipment, servers, graphic cards, desktop, Ultrabook and notebook computers.
The IRFH4257D features IR's latest generation silicon and proprietary packaging technology which offers excellent thermal performance, low on-state resistance (RDS(ON)) and gate charge (Qg). These features deliver superior power density and lower switching losses in a compact 4x5 power block.
The IRFH4257D is qualified to industrial grade and moisture sensitivity level 1 (MSL1), and features an environmentally friendly, lead-free and RoHS compliant bill of materials.
Pricing for the IRFH4257D FastIRFET™ starts at US $0.99 in 10,000-unit quantities. Production orders are available immediately. Prices are subject to change.
