Description

Product Overview

The BB844 is a Silicon Variable Capacitance Diode designed for FM radio tuners with an extended frequency band of 77MHz to 108MHz. It is engineered for applications requiring a back-to-back diode configuration to optimize signal distortion and detuning. This diode offers a high tuning ratio at low supply voltages, making it suitable for car radio applications. Featuring a monolithic chip with a common cathode for perfect dual diode tracking, it also boasts good C-V linearity and a high figure of merit. The BB844 is available in a Pb-free (RoHS compliant) SOT23 package.
