Description
The MA45430 series are abrupt junction silicon tuning
varactors in the SOT-23 surface mount package. These
thermal oxide passivated diodes feature high capacitance
ratio and quality factor. They are well suited for tuning in
the HF to UHF frequency bands. The standard capaci-
tance tolerance is ±10%, with tighter tolerances available.
Capacitance matching at one or more bias voltages is
also available.
Applications
The MA45430 series tuning varactor is useful for tuning
applications in the HF through UHF ranges. Applications
include VCOs and voltage tuned lters in radios, cable
TV tuners and test instruments where low cost and excel-
lent lot-to-lot repeatability are critical.
Ordering Information
The part numbers shown are for single diodes. When
ordering diodes in common cathode pairs add suffix
“CK.” For example, MA45436CK species model number
MA45436 as a common cathode pair. To order parts on
tape and reel add sufx T/R to the end of the part num-
ber. i.e. MA45436CK - T/R.
Mounting Information
The diagram below indicates the recommended mount-
ing pad configuration for the SOT-23 package. Solder
paste containing ux should be screened onto the pads
to a thickness of 0.005 inches. The SOT-23 device is
placed in position, rmly adhering to the solder paste.
Permanent attachment is performed by a reow soldering
procedure. The tab temperature must not exceed 275°C
and the body temperature must not exceed 250°C.
