Description

BB139 is 30V, VHF / FM Varactor Diode. Variable capacitance diode is a type of diode that exhibits a variable capacitance when a voltage is applied across it. It is also known as a voltage-variable capacitor or tuning diode. Varicap diodes are primarily used in electronic circuits for tuning and frequency modulation in applications such as radio receivers, television tuners, and voltage-controlled oscillators.
