The SMV1413-001 is a hyperabrupt junction varactor diode manufactured by Alpha Industries (now Skyworks Solutions). Varactor diodes, also known as varicap diodes, are semiconductor devices whose capacitance varies with the voltage applied to their terminals. This property makes them useful in voltage-controlled oscillators (VCOs), tunable filters, and other applications where voltage-variable capacitance is required.
