Infineon BB644 BB664 Variable Capacitance Diode Datasheet
The BB644 and BB664 series are silicon variable capacitance diodes designed for VHF TV tuners. They offer a high capacitance ratio, low series inductance and resistance, and excellent uniformity due to an in‑line matching assembly procedure.
The document provides maximum ratings, electrical characteristics, capacitance versus voltage curves, and temperature coefficients for the diodes, enabling designers to select appropriate parts for their applications.
