SILICON LOW VOLTAGE HYPERABRUPT VARACTOR DIODES  
ZV950V2, ZV952V2, ZV953V2, ZMDC953, FSD273  
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 perform ance. These parts can be used with control voltages from  
0.5V to 2.5V, m aking them ideal for 3 volt system s. Available in  
m iniature surface m ount packages.  
Features  
• Close tolerance C-V characteristics  
• Tuning from 0.5 to 2.5 Volts to suit 3 volt system s  
• Low IR (typically 10pA)  
• Excellent phase noise perform ance  
• High Q at low voltage  
• Miniature surface m ount packages  
• Band selection for DAB applications - FSD273  
Applications  
• VCXO and TCXO  
• Wireless com m unications  
• Pagers  
• Mobile radio  
• Digital Radio receivers

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. Shipm ents containing several reels  
m ay have reels in different bands. It is not possible to supply a specific band as processing affects which bands  
are available

FSD273 is a band selected version of the ZMDC953. Product is supplied in reels containing a  
single capacitance band. Shipm ents of several reels m ay contain reels of different bands. It is  
not possible for custom ers to specify a particular band, because availability is process depend-  
ent.
