BB178

VHF variable capacitance diode

Rev. 3 — 5 September 2011

Product data sheet

1. Product profile

1.1 General description

The BB178 is a planar technology variable capacitance diode, in a SOD523 (SC-79) ultra

small plastic package. The excellent matching performance is achieved by gliding

matching and a Direct Matching Assembly (DMA) procedure.

1.2 Features and benefits

 Excellent linearity

 Excellent matching to 2 % DMA

 Ultra small plastic SMD package

 C_d(28V): 2.6 pF; C_d(1V)to C_d(28V)ratio: 15

 Very low series resistance.

1.3 Applications

 Electronic tuning in VHF television tuners, band B up to 460 MHz

 Voltage Controlled Oscillators (VCO).
