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 ﬁlters 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 speciﬁes model number

MA45436 as a common cathode pair. To order parts on

tape and reel add sufﬁx T/R to the end of the part num-

ber. i.e. MA45436CK - T/R.

Mounting Information

Reverse Voltage

30 V

The diagram below indicates the recommended mount-

ing pad configuration for the SOT-23 package. Solder

paste containing ﬂux should be screened onto the pads

to a thickness of 0.005 inches. The SOT-23 device is

placed in position, ﬁrmly adhering to the solder paste.

Forward Current

50 mA

Junction Operating Temperature

Storage Temperature

250 mW

-55°C to +150°C

Note:

1. At 25°C case temperature. Derate linearly to 0 mW at 150°C.

Permanent attachment is performed by a reﬂow soldering

procedure. The tab temperature must not exceed 275°C

and the body temperature must not exceed 250°C.
