| SMALL-SIGNAL DIODE MC2837 FOR HIGH SPEED SWITCHING APPLICATION SILICON EPITAXIAL TYPE(SERIES TYPE) DESCRIPTION MC2837 is a super mini package plastic seal type silicon epitaxial type double diode,especially designed for high speed switching application. Due to the small pin capacitance,short switching time(reverse recovery 0.95 0.4 time),It is most suitable for high speed switching application and 2.9 1.90 limitter,clipper application. 0.5 2.5 1.5 0.5 OUTLINE DRAWING Unit FEATURE Small pin capacitance Quick switching time 1.1 0.8 High voltage Series connected two elements Good two element characteristics Double and super mini package for mounting 00.1 0.16 0.95 APPLICATION For general high speed switching of audio machine,VCR.
