Features M Industry Standard Outlines: SOD323 and SOT23 Packages @ High Q Abrupt and Hyperabrupt Junction Designs M@ Single, Common Anode and Common Cathode Configurations @ Available for 3 Volt Battery Operated Circuits @ Priced for High Volume Commercial Applications @ Available in Tape and Reel @ Also Available as Chips Description The surface mount plastic varactor diodes are designed for RF and Microwave applications in VCOs, electronically tunable filters and matching networks. Package offerings include the SOT23 and the small footprint SOD-323 package. Alpha offers a comprehensive capability in capacitance values, package options and voltage ratings all aggressively priced for high volume commercial applications. The SMV 1247-001 to SMV1255001 varactors were specifically designed for battery operated applications where 3 to 5 volts is available. These varactors have capacitance ratios of greater than 12 from 0.3 to 4.7 volts. Alphas hyperabrupt varactors are available in a wide variety of tightly specified capacitance values and Plastic Packaged Surface Mount Varactor Diodes SS SSS ooo aaarpDpDhnaOoODoOoDDDDD Maximum Ratings (T, = 25C) Forward Current: 100 mA Power Dissipation: 250 mW Junction Temperature: 125C Storage Temperature: 55 to 150C Operating Temperature: 55 to 125C high capacitance ratios. They are available as single junctions and common cathode configurations where they may be employed in a backtoback orientation to reduce distortion. Alphas abrupt junction varactors are noted for extremely high Q factor and are the preferred choice in applications that require low phase noise and high temperature stability. The inductance of the SOT23 package is typically 1.5 nH for each junction. Employing a common cathode SOT-23 with the varactor junctions connected in parallel reduces the inductance to approximately 0.9 nH. The inductance of a varactor in the SOD-323 package is approximately 1.5 nH.

Capitance measured at 1 MHz. 2. For multiple junction packages specifications apply to single junction. Unpackaged chips are available for purchase by replacing the dash number with 000. For example, to purchase the chip from the SMV1 408-001, the part number becomes SMV1408000. The package capacitance of 0.13 pF should be subtracted from the Cr specifications to indicate junction capacitance. > Chips available through distribution: SMV1212-000 SMV1213-000 SMV1214000 SMV1233-000 SMV1236000 Alpha Industries [617] 935-5150 e Fax [617] 824-4579 E-mail sales@alphaind.com e Visit our web site: www.alphaind.com 2-7Plastic Packaged Surface Mount Varactor Diodes Typical Capacitance Curves 100.0 1000 10.0 SMV1237 100 f Lc c E & SMV1236 & P 8 SMV1235 8 L c c BS SMV1229 SMV1234 OS 1.05 3 10 g E SMV1233 g SMV 1228 w E w SMV1207 oO C o SMV1227 L smvi244 SMV1205 SMV1206 0.1 Ll | Ll | Ll | Ll | Ll 1 Ll | Ll | Ll | 1 0 2 4 6 8 10 0 2 4 6 8 10 12 14 16 18 20 Reverse Voltage (Volts) Reverse Voltage (Volts) Capacitance vs. Reverse Voltage Capacitance vs. Reverse Voltage 100 - 1 E 8 Ss a i > 2 Sy @ 10 SMV1422 a re N SMVv1421 5 S = IN SMV1419 a. w SMV1417 8 3 SMV1415 SMV1413 SMV1410 1 qlitiltiti tls |r SMV1408 o 10 10.0 0 2 4 6 8 10 12 14 16 18 20 Reverse Voltage (Volts) .
