BB 804 SF2 E6327

The BB 804 SF2 E6327 is a variable capacitance diode (varactor) manufactured by Infineon Technologies, designed for applications requiring voltage-controlled capacitance. This component features a 1 pair common cathode configuration, providing two diodes in a single SOT-23 package for space-efficient circuit designs.

Key electrical characteristics include a maximum reverse voltage of 18V, a typical capacitance of 47.5pF at 2V and 1MHz, and a capacitance ratio of 1.71 (C2/C8). The diode exhibits a quality factor (Q) of 200 at 2V and 100MHz, indicating good performance for RF applications. The operating temperature range spans from -55°C to 125°C (junction temperature), suitable for demanding environments.

The device is surface mountable and comes in a TO-236-3, SC-59, or SOT-23-3 package with a PG-SOT23 supplier device package. This compact form factor makes it suitable for high-density PCB designs in consumer electronics, telecommunications, and RF tuning circuits.

As a variable capacitance diode, this component is commonly used in voltage-controlled oscillators (VCOs), phase-locked loops (PLLs), and RF tuning applications where precise capacitance variation with applied voltage is required. The common cathode configuration simplifies circuit layout by sharing a common connection point for both diodes.
