830 series
Silicon 25V hyperabrupt varactor diodes
ZC829, ZDC833, ZMV829, ZMDC830 and ZV831
Description
A range of silicon varactor diodes for use in
frequency control and filtering. Featuring
closely controlled CV characteristics and high
Q. Low reverse current ensures very low phase
noise performance. Available in single or dual
common cathode format in a wide rage of
miniature surface mount packages.
Features
• Close tolerance CV characteristics
• High tuning ratio
•Low I
R
(typically 200pA)
• Excellent phase noise performance
•High Q
• Range of miniature surface mount packages
Applications
• VCXO and TCXO
• Wireless communications
• Pagers
• Mobile radio
Where steeper CV slopes are required there is the 12V hyperabrupt range:
ZC930, ZMV930, ZV930 and ZV931
SOT23 SOT323
SOD523 SOD323
