Schottky Diodes are built in hermetic packages.

Press Release Summary:



Models APT15S20G and APT30S20C are 200 V Schottky diodes rated at 15 and 30 A, respectively. They can replace Epitaxial Diodes as output rectifiers in 48 V DC-DC converters and as free wheeling and anti-parallel diodes in low-voltage converters. Units come in TO-257 and TO-254 packages for Hi-Rel applications or harsh environments. Low forward voltage drop minimizes conduction losses, and soft reverse recovery characteristics result in reduced EMI.



Original Press Release:



New 200 Volt Hermetic Schottky Diodes Improves Efficiency of 48 Volt Outputs Used In Harsh Enviroments



Bend OR..... Advanced Power Technology (NASDAQ: APTI) is pleased to announce its new product line of 200 volt rugged Schottky Diodes built in hermetic packages. APT's Schottky Diodes offer several dramatic improvements over existing Epitaxial Diodes (FREDs), including:

o Lower forward voltage drop (VF) to minimize conduction losses enabling higher power conversion efficiencies
o Softer reverse recovery characteristics, resulting in reduced EMI
o Avalanche energy rated for improved reliability
o Built in hermetic TO-257 and TO-254 packages for Hi-Rel applications or harsh environments where added protection is required
o Military screening available

Power supply designers can now use APT's new Schottky Diodes to increase the efficiency of their designs. Designs with APT's Schottky Diodes will have 10-15% lower losses then FRED's with the same voltage ratings. These cost effective Schottky Diodes can replace FRED's as output rectifiers in high power 48 Volt DC-DC converters and as free wheeling and anti-parallel diodes in low voltage converters.

200 volt, 15 Amp and 30 Amp Schottky are available in TO-257 and TO-254 hermetic packages. Data sheets describing the features and benefits are available to assist the designer. These may be downloaded from APT's website at www.advancedpower.com or obtained from the factory.
