Packaging and Temperature Range
The ACPL-C79x isolation amplifiers are available in a compact 8-pin stretched SO-8 package for automatic SMT assembly and are RoHS compliant. All devices operate over a very wide temperature range, -40 ° C to +105° C.
In order to achieve high insulation ratings, package creepage and clearance is 8 mm and distance-through-isolation, DTI, is 0.5 mm.
U.S. Pricing and Availability
Avago’s ACPL-C79B, ACPL-C79A and ACPL-C790 are priced at $6.25, $5.00 and $3.75 respectively, each in 10,000 piece quantities.

2nd generation SiC (Silicon Carbide) Schottky announced by Infineon Technologies
Infineon Makes 2nd Generation of its ThinQ! Silicon Carbide Schottky Diodes Available in Fully Isolated TO-220 FullPAK Package
Infineon Technologies have announced the availability of its 2nd generation SiC (Silicon Carbide) Schottky diodes in the TO-220 FullPAK package. The new TO220 FullPak portfolio combines the high electrical performance standards of the 2nd generation ThinQ!™ SiC Schottky diodes with the advantages of a fully isolated package, including easier and more reliable mounting without having to use isolating bushing and foil.
Uniquely, the new TO220 FullPAK devices show a similar junction-to-heatsink thermal resistance as the standard non-isolated TO- 220 devices. This is accomplished by using patented diffusion soldering technique from Infineon, which strongly reduces the “chip-to- leadframe” thermal resistance and effectively compensates for the FullPAK´s internal isolation layer. Infineon offers the 600V FullPAK portfolio in current ratings from 2A to 6A, making it the industry´s broadest portfolio of SiC diodes in this package type.
Silicon Carbide (SiC) is a revolutionary material for power semiconductors, with physical properties that far outperform Si power devices. Key features are a benchmark switching behavior, no reverse recovery, virtually no temperature influence on the switching behavior and a standard operating temperature of -55°C to 175°C. Main application areas for SiC Schottky diodes are active Power Factor Correction (PFC) in Switched Mode Power
