Three new package types, TEFP, EFP, and SFP, will be joined in addition to Current 0.6 × 0.3 (mm) size varicap diodes

Renesas Technology Expands its Lineup of Halogen-Free Resin Diode Products Three new package types, TEFP, EFP, and SFP, will be joined in addition to Current 0.6 × 0.3 (mm) size varicap diodes Tokyo, December 7, 2006 Renesas Technology Corp. today announced the expansion of its lineup of environmentally friendly halogen-free resin diodes with the addition of five new products. Sample shipments will begin in Japan on December 8, 2006. The five new products substitute environmentally friendly aluminum hydroxide* 1 for the halogen bromine* 2 used as a flame retardant in the epoxy resin. Three package types are available: TEFP, EFP, and SFP* 3 . PIN diodes*4 : HVL142AM-N HVL142AM-N (TEFP package), HVL142-N HVL142-N (EFP package) Schottky diodes*5 : HSL226-N HSL226-N (EFP package), HRD0103C-N HRD0103C-N (SFP package), HSD226-N HSD226-N (SFP package) The features of the halogen-free plastic-sealed diodes are as follows. (1) Uses halogen-free resin certified under the UL 94 standard of Underwriters Laboratories* 6 as V-0* 7 Changing the flame retardant used in the epoxy resin from bromine to aluminum hydroxide enables the resin used in the diode package to be certified as V-0 under the UL 94 standard of Underwriters Laboratories. The use of halogens is completely eliminated and overall environmental impact is reduced. (2) Delivers reliability and characteristics equivalent to current diodes Changing the flame retardant used in the epoxy resin to aluminum hydroxide has no negative effect on the reliability or characteristics of the diodes. The new diodes are equivalent to current products and can be used interchangeably with them. < Development Background > Renesas Technology's efforts at environmental preservation are ongoing and include a shift to lead-free solder in compliance with the EU RoHS Directive* 8 . The bromine employed as a flame retardant in the epoxy resin used in semiconductor molds is not covered by the RoHS Directive, but it nevertheless is thought to have an adverse impact on the environment. Against this background and in consideration of the environmental effects, Renesas Technology has now, through the cooperation of a material manufacturer, created a technology uses aluminum hydroxide as a substitute for bromine while retaining the same flame retardant effectiveness. Renesas Technology first used the new technology in products such as the RKV653KP RKV653KP varicap diode* 9 supplied in a MP6 package. The products to be newly introduced extend the series and are available in TEFP, EFP, and SFP packages. - more - Renesas Technology will offer still more products in new environmentally friendly packages.
