| MA4ST1200 Series Low Tuning Voltage / Low Rs Silicon Hyperabrupt Varactor Diode Features * Low Series Resistance at Low Tuning Voltages * High Capacitance Ratio at Low Tuning Voltages * Surface Mount Plastic Packages : SC-79, SOD323, SC-70 ( 3L ) * SPC Process for Superior C vs V Repeatability * Lead-Free (RoHs Compliant) equivalents available with 260C reflow compatibility SC-70 (3 lead) SOD-323 Rev. V7 SC-79 Description M/A-COM's MA4ST1200 series is a highly repeatable, UHCVD/ion-implanted, hyperabrupt silicon tuning varactor in a cost effective surface mount package. This series of varactors is designed for high capacitance ratio, and high Q for low battery voltage operation. It is efficient for wide band tuning and low phase noise application where the supply voltage is limited to 5 volts or less. The Varactors are offered as Singles in SC-79, and SOD-323 along with a Common Cathode version offered in the SC-70, 3 Lead. These diodes are offered with standard Sn/Pb plating , as well as with 100% matte Sn plating on our RohS compliant equivalent devices. Absolute Maximum Ratings 1,2 @ TA=+25 C (Unless Otherwise Noted) Parameter Reverse Voltage Forward Current Operating Temperature Storage Temperature Absolute Maximum 12 V 50 mA -55 C to +125 C -55 C to +125 C 1. Operation of this device above any one of these parameters may cause permanent damage. 2.

MA4ST1200 Series Low Tuning Voltage / Low Rs Silicon Hyperabrupt Varactor Diode Mounting Information The illustration indicates the recommended mounting pad configuration for the SC-79, SOT-323 and SOD-323 packages. Solder paste containing flux should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package is placed in position, firmly adhering to the solder paste. Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed +275 C and the body temperature does not exceed +250 C, for standard models and +260 C for the RoHS compliant devices.
