It features a single-diode configuration housed in an SOT-23 surface-mount package. The device operates with a peak reverse voltage of 15 V and exhibits a capacitance of 2 pF at 6 V and 50 MHz. It has a capacitance ratio of 3.4 under C1/C6 conditions. The component supports a junction temperature range from -55°C to 125°C and is RoHS compliant. Factory packaging quantities are listed as 3,000 units per reel.

Feature Summary

• Single varactor diode structure optimized for RF tuning circuits
• Surface-mount SOT-23 package for compact board integration
• Capacitance ratio of 3.4 for effective frequency modulation

Applications

• RF tuning circuits requiring variable capacitance
• Voltage-controlled oscillators (VCOs)
• Frequency synthesizers and phase-locked loops (PLLs)

Procurement Notes

Verify the current lifecycle status before procurement, as the product is listed as End-of-Life or Last Time Buy in multiple distributor records. Confirm availability through authorized channels, noting that stock may be limited or restricted. Ensure compliance with RoHS standards and check for any specific handling requirements associated with the SOT-23 package during assembly.

Selection Notes

Select this component when a single varactor diode with a 15 V peak reverse voltage rating is required. The SOT-23 package suits space-constrained designs. Verify that the 2 pF capacitance at 6 V meets the circuit's tuning range needs. Consider the -55°C to 125°C operating temperature range for environmental suitability. Compare against other SMV series parts if different capacitance ratios or packages are needed.

Part Context

The SMV1222-001LF belongs to the SMV12xx series of varactor diodes from Skyworks Solutions. This series typically offers low inductance and high Q-factor characteristics suitable for RF applications. The part shares design similarities with other single-varactor devices in the lineup but differs in specific electrical parameters like capacitance and voltage ratings. It is distinct from PIN diodes or switches offered by the same manufacturer.
