•Industry-leading quality
International Rectifier offers a series of 25V and 30V N-channel trench HEXFET® power
MOSFETs featuring enhanced switching performance for synchronous buck converter
and battery protection in computing applications for consumer and networking sectors.
The family of MOSFETs utilizes IR’s proven silicon technology to deliver benchmark on-state
resistance (RDS(on)) and improved switching performance. The devices’ low conduction
losses improve full-load efficiency and thermal performance while low switching losses
help to achieve high efficiency even at light loads.
Single and dual N-channel MOSFETs are available. Single devices are offered in a PQFN
5x6mm and 3x3mm package to provide improved power density when compared with an
SO-8 package while keeping the same pin-out configuration. The single devices are also
offered in D-PAK, I-PAK, and SO-8 packages while dual devices are offered in TSSOP-8
and SO-8 packages. Depending upon application, the dual SO-8 MOSFETs allow a ‘two for
one’ exchange to reduce component count. The MOSFETs are RoHS compliant and can be
offered as Halogen free.
