The SMV1263-040LF is a Silicon Variable Capacitance Diode designed as a customer customizable switchable varicap diode. It is built on a planar process, and usually supplied in a Hermetically Sealed capsule.

The devices are used in applications such as tuners, oscillators, filters and amplifiers in consumer video and audio systems. The do so by varying the voltage across its terminals to create a capacitance change. This in turn allows for frequency control, allowing an audio or video signal to be tuned.

The SMV1263-040LF works by using charge layer modulation across the diode’s junction. This process occurs when a voltage is applied to the electrode, creating an electric field. As the field varies, the mobility of the electrons is altered, thus changing the amount of charge stored at the depletion region. This variance results in a change in capacitance.

The device has an integrated cusp junction, which allows for the control of the spontaneous breakthrough voltage. This in turn increases the dynamic range of the diode; by maintaining the capacitance difference instead of diminishing it when the voltage is increased across the terminals.

The planar process also provides an advantage of improved thermal stability and minimized hysteresis. This helps when combining parts such as a wideband amplifier, limiter and modulator.

The main benefit of the SMV1263-040LF device is its flexibility. Depending on the application, the operating temperature and the voltage variation ranges specified can be adjusted. For example in applications like FM tuners, capacitor banks with over 100 pF can be used.

Overall, the SMV1263-040LF is an advanced Variable Capacitance Diode. Its flexibility makes it an ideal choice for applications requiring a tunable, frequency controlled switch. Its planar process design allows for improved thermal stability and decreased hysteresis, making it more reliable and easier to integrate into complex systems.
