Microsemi Corp. (Irvine, CA) unveiled the first in a series of commercial
silicon carbide (SiC) Schottky diodes housed in the company’s Powermite surface-mount packages.
The devices, UPSC200, 400 and 600, and UPSC203, 403 and 603 Series, are rated
at 1A-600V and 4A-600V. The UPSC200, 400 and 600 feature a maximum current rating of 1A, a forward voltage drop of 1.6V typical and a reverse leakage of 20µA. The UPSC4600 has a maximum current rating of 4A, a forward voltage drop of 1.7V typical and a reverse leakage of 20µA.
The UPSC200, 400 and 600 are packaged in the two-lead Powermite package, with a footprint of 2.54mm x 2.67mm. The UPSC4600 is
packaged in Microsemi’s three-lead Powermite 3 package, with a 4.82mm x 5.33mm footprint.
"These new silicon carbide devices are powerful additions to our line of surface-mount Schottky diodes," said Manuel Lynch, vice president of business development. "We expect their combination of efficiency and high voltage to be particularly
valuable in cardioverter defibrillator applications, military aircraft and high-voltage telecommunications switching equipment."
Both devices are available now for sampling and volume shipment. The UPSC200, 400 and 600 Series are priced at $15 each and the UPSC203, 403 and 603 Series are priced at $25 each, both in quantities of 1,000.
