SMSSMV20413 SMV20413-01 Single Varactor (Tuning) Diode 22pF VARACTOR DIODES - PRODUCT DESCRIPTION Varicap Diode, Varactor Diode, Variable Capacitance Diode or Tuning Diode is a type of diode which has a variable capacitance that is a function of the voltage impressed on its terminals. Varactors are operated reverse-biased so no current flows, but since the thickness of the depletion zone varies with the applied bias voltage, the capacitance of the diode can be made to vary. Generally, the depletion region thickness is proportional to the square root of the applied voltage; and capacitance is inversely proportional to the depletion region thickness. Thus, the capacitance is inversely proportional to the square root of applied voltage. All diodes exhibit this phenomenon to some degree, but specially made varactor diodes exploit the effect to boost the capacitance and variability range achieved - most diode fabrication attempts to achieve the opposite. Varactors are principally used as a voltage-controlled capacitor, rather than as rectifiers. They are commonly used in parametric amplifiers, parametric oscillators and voltage-controlled oscillators as part of phase-locked loops and frequency synthesizers. Single Varactor Diodes BD series are available in die form in two configurations, Top Cathode XXXX-BD or Top Anode XXXXA-BD. In die form, these products are ideal for high reliability hybrid circuits and multi chip module applications. Common Cathode or Common Anode Varactor Diodes BD series are available in die form in single configuration: Common Cathode in TOP ANODE configuration and Common Anode in TOP CATHODE configuration. HIGH RELIABILITY BARE DIE AND SYSTEM IN PACKAGE - SHORT APPLICATION NOTE COB (Chip on Board) and SiP (System-in-Package) are integrating proven mature products in bare die of mixed technologies i.e. Si, GaAs, GaN, InP, passive components, etc that cannot be easily implemented in SOC (System-on-Chip) technology. COB and SiP have small size footprint, high density, shorter design cycle time, easier to redesign and rework, use simpler and less expensive assembly process. For extreme applications the bare die has to withstand also harsh environmental conditions without the protection of a package. KGD, Known Good Die concept is no longer satisfactory if the die cannot withstand harsh environmental conditions and degrades. Standard semiconductor devices supplied by many manufacturers in bare die are build with exposed aluminum pads that are extremely sensitive to moisture and corrosive components of the atmosphere. Semiconix has reengineered industry standard products and now offers known good die for bare die applications with gold interconnection and well-engineered materials that further enhance the die reliability. Semiconix also offers Silicon Printed Circuit Board technology with integrated passive components as a complete high reliability SIP solution for medical, military and space applications. See AN-SMX-001 DISCRETE SEMICONDUCTORS MANUFACTURING PROCESS Discrete semiconductors are manufactured using Semiconix in house high reliability semiconductor manufacturing processes. All semiconductor devices employ precision doping via ion implantation, silicon nitride junction passivation, platinum silicided contacts and gold interconnect metallization for best performance and reliability. MNOS capacitors, Tantalum Nitride TaN or Sichrome SiCr thin film resistors are easily integrated with discrete semiconductors on same chip to obtain standard and custom complex discrete device solutions.

For AuSn or AuGe die attach process, Ti/Pt/Au or Ti/Pd/Au are recommended backside metallization. For soft solder die attach, backside metallization may be any of Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au. For silver filled conductive epoxy die attach, AuSi as well as Ti/Ni/Au, Ti/Pt/Au, Ti/Pd/Au may be used. In general, after die attach, prior to wire bonding operation an oxygen RF plasma clean operation is recommended. IMPORTANT NOTE: Aluminum wire should not be used with gold pads due to potential reliability problem known as purple plague. Same it applies to Aluminum bonding pads with gold wire! In the transition from SnPb solder to lead free and RoHS compliant packaging and assembly processes the reflow temperature has increased in some cases from 180°C to 220°C. This may cause an increase of the rate of formation of gold aluminum intermetallic compounds that are brittle and are conducive to increased contact resistance and or bond failure.
