Microsemi Corp. announced that DSCC qualification has been granted for its 200 volt, 400 volt and 600 volt family of MIL-PRF-19500/590 ultrafast rectifiers in a compact thermally matched glass package.
Microsemi's MIL-PRF-19500/590 rectifiers maintain ultrafast switching characteristics even at extremely high temperatures. This stability is important for more efficient high frequency switching regulated power supplies and other applications requiring ultrafast switching speeds. Previously, the only DSCC-qualified ultrafast devices in this particular compact size package and current ratings were limited to 150 volts (1N5807 through 1N5811 qualification). While Microsemi's 1N6626 through 1N6628 qualification enable applications up to 600 volts, the company is continuing work to qualify the /590 family up to 1000 volts (1N6629 through 1N6631).
The new DSCC qualifications for Microsemi Part Numbers 1N6626 through 1N6628 qualifications include JAN, JANTX and JANTXV quality levels. Both axial and surface mount MELF packages are available for 2.3 Amp applications of 200V, 400V and 600V.
