Semicoa has implemented a new ceramic surface mount package for their qualified rectifier diodes from MIL-PRF-19500/477
Semicoa and their ceramic package
Semicoa is a supplier that design and development of bipolar power devices for high-reliability military, defense, aerospace, and space applications for 50 years.
Recently, has announced a new ceramic surface mount package called UMC, for their ultrafast rectifiers diodes from MIL-PRF-19500/477. The new UMC package improves the traditional glass melf packages in these aspects:
- Pick and place friendly
- Fully laser marked part-number, date code, serial number
- Cathode identification clearly visible
- Positive verification of solder attach through the use of castellations
- Near zero CTE mismatch
- A ceramic lead ensures hermeticity to the fine leak level
Versus problems in traditional glass melf packages:
- Difficult automatic pick and place
- No marked serial number on the part
- Lack of hermeticity
- Possibility of crack the glass
The JANS1N5806UMC, JANS1N5802UMC, JANS1N5804UMC ultrafast rectifiers diodes are now qualified on the DLA’s Land and Maritime QPL-19500.
