SVC270-TL-E

Overview

The SVC270-TL-E is a dual common cathode varactor diode designed for FM electronic tuning applications. It features an excellent large input characteristic and operates with a maximum reverse voltage of 16V. The device provides a minimum capacitance of 25.1pF at 8V (1MHz) and achieves a tuning ratio of 1.65:1. It requires a minimum quality factor of 100 and is housed in a 3-pin MCPH package.

Feature Summary

• Dual common cathode configuration optimized for FM electronic tuning
• Excellent large input characteristic for signal handling
• High quality factor ensuring stable RF performance

Applications

• FM radio receiver tuning circuits
• Voltage-controlled oscillator (VCO) frequency adjustment
• RF filter tuning networks

Procurement Notes

Verify the specific suffix TL-E against official onsemi documentation to confirm tape and reel packaging specifications. Ensure the component matches the required 16V reverse voltage rating and 3-pin MCPH package dimensions for your PCB layout. Cross-reference the datasheet for any updates regarding RoHS compliance or manufacturing site changes before finalizing procurement orders.

Selection Notes

Select this component when a dual varactor structure is required for balanced tuning in FM applications. The 16V rating suits standard low-voltage RF systems. Consider the 25.1pF minimum capacitance and 1.65:1 tuning ratio to ensure adequate frequency coverage. Verify that the MCPH package fits within the available board space constraints.

Part Context

This part belongs to the varactor diode category, specifically engineered for frequency modulation tuning. Unlike single varactors, the dual common cathode design allows for differential tuning or push-pull configurations in RF circuits. It serves as a critical passive component in analog radio receivers and tunable oscillators where precise capacitance control via voltage is necessary.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users must consult official onsemi resources or authorized distributors for verified equivalents. Do not assume functional compatibility with other dual varactor devices without verifying electrical parameters such as capacitance ratios and reverse voltage ratings.
