SVC348S-AL

Overview

The SVC348S-AL is a twin-type varactor diode manufactured by onsemi, designed specifically for AM electronic tuning applications. It features a common cathode configuration housed in a 3-SPA through-hole package. The device offers a high capacitance ratio of 18.5 (measured at C1/C8) and supports a maximum peak reverse voltage of 16 V. This component provides high quality factor performance suitable for precise variable capacitance requirements in radio frequency circuits.

Feature Summary

• Twin type varactor diode structure optimized for AM electronic tuning
• High capacitance ratio ensuring effective variable capacitance control
• Common cathode configuration for simplified circuit integration

Applications

• AM electronic tuning circuits
• Radio frequency variable capacitance applications
• Amplitude modulation receiver systems

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging format, as the device may be available in tape reel configurations. Confirm that the 3-SPA through-hole package matches the intended PCB layout requirements. Ensure storage conditions adhere to dry storage cabinet standards with humidity protection packages to maintain component integrity prior to assembly.

Selection Notes

Select this component when a dual varactor with common cathode topology is required for AM tuning. The 16 V peak reverse voltage rating defines the operational limits. The high capacitance ratio is critical for achieving desired tuning linearity. Verify that the through-hole 3-SPA package is compatible with the manufacturing process and mechanical constraints of the target design.

Part Context

This part belongs to the variable capacitance diode family from onsemi. It serves as a specialized component for analog radio frequency tuning rather than general-purpose rectification. The twin configuration allows for balanced tuning or differential applications within AM broadcast band receivers.
