GC1510-30

Overview

The GC1510-30 is a silicon abrupt junction tuning varactor diode from the GC1500 series, manufactured by Microsemi (now part of Microchip Technology). It features a minimum breakdown voltage of 30 V at 10 uA and operates within a temperature range of -55°C to +125°C. The device provides a nominal capacitance of 5.6 pF with a tolerance of ±10% and a minimum quality factor of 2600 at 50 MHz. It exhibits a minimum capacitance ratio of 4.0 and a thermal coefficient of capacitance of 300 ppm/°C at 4 Volts.

Feature Summary

• High Q factor and low series resistance for efficient signal tuning
• Abrupt junction design optimized for low phase noise applications
• RoHS compliant construction with gold-plated terminations

Applications

• VHF through Ku Band narrow to moderate bandwidth tuning
• Low phase noise voltage controlled oscillators
• Low loss voltage variable filters
• Phase shifters

Procurement Notes

Verify the specific package style suffix when ordering, as standard configurations may vary. Confirm RoHS compliance status and terminal finish requirements directly with the manufacturer or authorized distributors. Ensure ESD handling precautions are observed during storage and assembly due to component sensitivity.

Selection Notes

Select this component based on required capacitance values ranging from 0.4 pF to 10.0 pF within the GC1500 series. Consider the trade-off between Q factor and capacitance ratio for specific frequency bands. Verify that the 30 V breakdown rating meets the circuit's reverse bias requirements and that the operating temperature range aligns with environmental conditions.

Part Context

The GC1510-30 belongs to the GC1500 series of control devices designed for microwave applications. This series offers a wide selection of capacitance values tailored for VHF to Ku band frequencies. The components are engineered to provide high performance in tuning circuits where low insertion loss and stable electrical characteristics are critical.

Replacement Considerations

Direct substitutes include other models within the GC1500 series such as GC1509-30 or GC1511-30, depending on the required capacitance value. Alternative abrupt junction varactors from other manufacturers may be considered if they meet the 30 V breakdown and Q factor specifications.
