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
time),It is most suitable for high speed switching application and
limitter,clipper application.
FEATURE
● Small pin capacitance
● Quick switching time
●High voltage
●Series connected two elements
●Good two element characteristics
● Double and super mini package for mounting
APPLICATION
For general high speed switching of audio machine,VCR.
