The physical dimensions for the DLCC ceramic packages are designed to fully utilise the recommended solder footprint for the popular MELF packages, and are therefore a drop in replacement for existing board design. Thermal vias improve the heat transfer to the solder pads reducing the diode junction temperature and increasing operating lifetime; options are also available to allow the lid to be connected to the Anode or Cathode. Connecting the metal lid to a known electrical potential stops deep dielectric discharge in space applications; as described in the Space Weather link on Semelab’s web site. www.semelab.co.uk/mil/DLCC
