It is designed for voltage-controlled oscillator (VCO) tuning, phase-shift networks, and bandpass filter adjustment where a predictable capacitance-versus-voltage curve is needed. The 3.8 capacitance ratio (C2/C8) gives a useful tuning range for a 2:1 frequency sweep in LC tank circuits. At 8 V reverse bias the capacitance measures 13 pF (at 1 MHz), and the peak reverse voltage rating of 18 V sets the upper limit of the tuning control voltage. There is no announced last-time-buy window, so the part is safe to specify for new production builds and for sustaining legacy BOM lines. ## Package and mounting — SOT-23-3 with common cathode The three-lead SOT-23-3 (PG-SOT23) houses two varactors with a shared cathode. The common cathode is the centre pin in the standard SOT-23 pinout; the two anodes are the outer pins. Surface-mount soldering follows standard SOT-23 reflow profiles. The -55°C to 150°C junction rating means the part can be placed near hot components — a 1 W resistor or a linear regulator dissipating into the board — without derating the tuning capacitance. No heatsinking is needed; the junction-to-ambient thermal path through the small leadframe is adequate for the low bias currents (microamps) typical of varactor operation.","metaTitle":"Infineon BB844E6327HTSA1 Varactor Diode, Dual Common Cathode","metaDescription":"BB844E6327HTSA1 dual varactor diode from Infineon: 13pF at 8V, capacitance ratio 3.8, 18V peak reverse, -55 to 150°C.
