APPLICATIONS Electronic tuning in television tuners with extended VHF range Voltage controlled oscillators (VCO). DESCRIPTION The BB147 is a variable capacitance diode, fabricated in planar technology, and encapsulated in the SOD323 very small plastic SMD package. The excellent matching performance is achieved by gliding matching and a direct matching assembly procedure. ELECTRICAL CHARACTERISTICS Tj = 25 °C; unless otherwise speci ed. SYMBOL IR rs Cd PARAMETER reverse current diode series resistance diode capacitance capacitance ratio CONDITIONS VR = 30 V; see Fig.3 VR = 30 V; Tj = 85 °C; see Fig.3 f .
