It is designed for voltage-controlled oscillator (VCO) tank circuits, RF tuners, and phase-locked loop (PLL) filter tuning where a reverse-bias voltage changes the junction capacitance to set the resonant frequency. Peak reverse voltage is rated at 12V, giving headroom for a typical 0V to 8V tuning line without approaching the breakdown region. For new designs, this means no LTB risk during the development cycle; for existing BOMs, the supply channel is stable through authorized distribution and independent stock.","metaTitle":"Infineon BBY6605WE6327 Varactor Diode, 13.5pF at 4.5V","metaDescription":"Infineon BBY6605WE6327 variable capacitance diode, 1 pair common cathode, 13.5pF @ 4.5V, 5.41 ratio, 12V Vr, -55 to 150°C, SOT-323.
