(ie: umx4000sm) the umx series meets rohs requirements per eu directive 2002/95/ec. important: for the most current data, consult our website: www.microsemi.com absolute maximum ratings at 25o c (unless otherwise specified) package condition um4000 um4900 pd (w) ( o c/w) pd (w) ( o c/w) a 25 o c pin temperature 25 6 37.5 4 ? in. total length to 25 o c contact 12 1.25 12 12.5 b & e free air 2.5 2.5 c 25 o c stud temperature 25 6 37.5 4 d 25 o c stud temperature 18.75 8 25 6 sm 25 o c end cap temperature 20 7 n/a all 1 us pulse (single) 100 kw 100 kw voltage ratings reverse voltage @ 10 ua um4000 um4900 100 um4001 um4901 200 um4002 um4902 400 - - 600 um4006 UM4906 1000 um4010 - key features ? voltage ratings to 1000 v ? power dissipation to 37.5 w ? series resistance rated at 0.5 ? ? carrier lifetime greater than 5 s ? non cavity design ? rohs compliant version available 1 ? thermally matched configuration ? low capacitance at 0 v bias ? low conductance at 0 v bias ? compatible with automatic insertion equipment 1- rohs compliant version is supplied with a matte tin finish.
