SVC390-AL

Overview

The SVC390-AL is a dual common cathode varactor diode manufactured by ON Semiconductor. It utilizes a hyper-abrupt junction silicon composite structure designed for low voltage electronic tuning applications, specifically in twin type AM radio circuits. The device features a maximum repetitive peak reverse voltage of 16 V and a nominal capacitance of 50 pF at zero bias. Key electrical characteristics include a minimum quality factor of 200 and a junction temperature rating up to 150°C. The component is housed in a SPAKVAR package and operates within a storage temperature range of -55°C to +150°C.

Feature Summary

• Hyper-abrupt junction type silicon composite construction
• Dual common cathode configuration for twin tuning applications
• High capacitance ratio and high quality factor performance

Applications

• AM electronic tuning circuits
• Twin type varactor diode applications
• Low voltage electronic tuning systems

Procurement Notes

Verify the manufacturer designation as ON Semiconductor rather than Sanyo Denki, as the source data attributes the SVC390 part number to ON Semiconductor. Confirm the specific suffix meaning if available from official documentation. Ensure compliance with EAR99 classification requirements during import or distribution processes.

Selection Notes

Select this component for applications requiring high Q factors and precise capacitance variation in low voltage environments. The dual common cathode design simplifies circuit layout for twin-tuned RF stages. Verify that the 16V reverse voltage rating meets the peak inverse voltage requirements of the target AM tuning circuit.

Part Context

The SVC390 belongs to the family of variable capacitance diodes used primarily in radio frequency tuning. Unlike standard abrupt junction diodes, the hyper-abrupt profile provides a more linear capacitance-voltage relationship, which is critical for maintaining consistent bandwidth in AM broadcast receivers across the tuning range.
