Siliconix Intros Si4880DY, Si4800DY and Si4890DY Power MOSFETs

May 09, 1999 by Jeff Shepard

Vishay Siliconix (Santa Clara, CA) announced three new power MOSFETs with improved specs for notebook computer and CPU point-of-use dc-to-dc conversion applications. The devices include the Si4880DY, which offers on-resistance of 8.5 millohms at a 10V gate drive, with gate charge of 19.5nC and turn-off times of 46ns. Intended for designs requiring the fastest possible switching, the Si4800DY offers a turn-off time of 22ns, which is claimed to be a record for this type of device, as well as on-resistance of 18.5 milliohms and gate charge of 8.7nC. The Si4890DY offers on-resistance of 12 milliohms, gate charge of 14nC and turn-off time of 35ns. The new MOSFETs are packaged in the LITTLE FOOT SO-8. Samples and production quantities are available now, with lead times of 8 to 10 weeks for larger orders. Pricing starts at $0.71 in 100,000-piece quantities.
