Description
HEXFET® Power MOSFETs from International Rectifier
utilize advanced processing techniques to achieve extremely low on-resistance per silicon area. This benefit,
combined with the ruggedized device design, that International Rectifier is well known for,
signer with an extremely efficient and reliable device
for battery and load management.
The TSSOP-8 package has 45% less footprint area than
the standard SO-8. This makes the TSSOP-8 an ideal
device for applications where printed circuit board space
is at a premium. The low profile (<1.2mm) allows it to fit
easily into extremely thin environments such as portable
electronics and PCMCIA cards.
