Targeting high performance computing and communications, International Rectifier has expanded its StrongIRFET family to include 20-30V devices. This family 
includes the company’s IRL6283M 20V DirectFET, featuring ultra-low on-state resistance (Rds(on)).
The company points out that this device features Rds(on) of only 500µOhm (typical) in a low profile 30mm2 DirectFET Medium Can package. This has the capability to significantly reduce conduction losses. As a result this makes it ideal for active ORing and electronic fuse (eFuse) applications.
The new device can be used from 3.3V, 5V or 12V rails and is claimed to offer 15 percent lower losses at 20A than similar PQFN devices in the same 30mm2 form factor, enabling designers to reduce part count in high current applications.
The company adds that, this latest device allows top-side cooling for enhanced electrical and thermal performance and wire bond-free construction for improved reliability. Moreover, the DirectFET package meets all RoHS requirements such as a completely lead-free bill of materials being well suited for long lifecycle designs.
Alternative high performance packages feature high-lead die attach under RoHS exemption 7(a) which is due to expire in 2016.
A datasheet and Spice Model are available on the International Rectifier website at http://www.irf.com.
