• Manufacturer Part Number: 1N5551D3A
• Description: Power Rectifier Diode
• Manufacturer: Semelab Group

MECHANICAL DATA
* The additional contact provides a connection to the lid in the application. Connecting the metal lid to a known electrical potential stops deep
dielectric discharge in space applications; see the Space Weather link
to be specified at order.
† The DLCC3 package design takes full advantage of the proven high reliability pedigree of the HTCC surface mount packaging technology,
which is easily integrated for automated assembly. Semelab has taken the existing standards for ceramic surface mount package manufacture
and added additional design features to enhance thermal performance, to present a competitive alternative for high reliability applications.
SOLDER PAD LAYOUT
Soldering temperature should be 260°C for a
maximum of 10 seconds.

The physical dimensions for the DLCC3 ceramic package are designed
to be different from the published dimensions for the “D-5B” and “E-
MELF” outlines. The DLCC3 design fully utilises the recommended
solder footprint for the “D-5B” / “E-MELF” Package, and as such
presents a drop in replacement for existing board designs.
