Overview

The SVC354S-TR-E-SY is a variable capacitance diode manufactured by Sanyo Semiconductor. It is designed for low-voltage electronic tuning applications, specifically serving as a twin-type varactor diode for AM radio circuits. The device features a diffused junction silicon composite structure housed in a small surface-mount package to support compact and slim equipment designs. Key electrical characteristics include a nominal capacitance of 351 pF at zero bias and a minimum breakdown voltage of 16 V. The component operates with a common cathode configuration containing two elements within a single plastic epoxy package.

Feature Summary

• Diffused junction type silicon composite varactor construction
• Twin-type design optimized for low-voltage AM electronic tuning
• High Q factor performance suitable for sensitive tuning circuits
• Surface mount packaging enabling compact and slim device integration

Applications

• Low-voltage AM electronic tuning circuits
• Compact consumer electronics requiring slim form factors
• Variable capacitance applications in radio frequency systems

Procurement Notes

Verify the manufacturer origin carefully, as Sanyo's semiconductor division was acquired by ROHM. Confirm the specific suffixes TR, E, and SY against official datasheets to ensure correct tape-and-reel packaging and environmental compliance status. Request the original data sheet from authorized distributors or ROHM directly to validate the part number authenticity and current production status before ordering.

Selection Notes

Select this component when designing AM tuner circuits that require low operating voltages around 5.5 V. Ensure the circuit design accommodates the 351 pF nominal capacitance and the specified 16 V breakdown limit. Verify that the surface mount package dimensions fit the PCB layout constraints for slim devices. Check if the high Q characteristic meets the signal integrity requirements of the target application.

Part Context

This part belongs to the SVC series of variable capacitance diodes produced by Sanyo Semiconductor. The series is characterized by its use in consumer electronics where space saving and low voltage operation are critical. The specific model indicates a twin-element configuration packaged for surface mount technology, reflecting the industry shift towards miniaturization in portable audio devices during the era of Sanyo's active semiconductor manufacturing.

Replacement Considerations

Since Sanyo Semiconductor is now part of ROHM, check for equivalent parts in the ROHM catalog. Look for other twin-type varactor diodes with similar capacitance values and low voltage ratings. Verify pin compatibility and package dimensions to ensure direct replacement without PCB redesign.
