Device Description
A range of silicon varactor diodes for use in frequency control and
filtering. Featuring closely controlled CV characteristics, low voltage
operation and high Q. Low reverse current ensures very low phase
noise performance. These parts can be used with control voltages from
0.5V to 2.5V, making them ideal for 3 volt systems.
Available in
miniature surface mount packages.

ZMDC953 is available banded to tighter capacitance range. This product has the order code FSD273TA.
Measured at VR=1.5V the bands are
Band A = 30.0 to 32.5
Band B = 32.3 to 34.7
Band C = 34.5 to 37.0
Product is supplied in reels. A banded reel will only contain a single band. Shipments containing several reels
may have reels in different bands. It is not possible to supply a specific band as processing affects which bands
are available

TYPICAL CHARACTERISTICS
ORDER CODES AND PART MARKING
FSD273 is a band selected version of the ZMDC953. Product is supplied in reels containing a
single capacitance band. Shipments of several reels may contain reels of different bands. It is
not possible for customers to specify a particular band, because availability is process depend-
ent.
