GC1500A-00

Overview

The GC1500A-00 is a silicon abrupt junction tuning varactor diode from the GC1500 series, designed for microwave applications. It features a minimum breakdown voltage of 30 V at 10 uA and a maximum leakage current of 0.02 uA at 25 Volts and 25°C. The device offers a nominal capacitance (CT) of 4 pF ±10% measured at 1 MHz, with a minimum quality factor of 5000 at -4V and 50 MHz. The capacitance ratio (CT0/CT-30) is a minimum of 4.2. Operating temperature ranges from -55°C to +125°C, with a thermal coefficient of capacitance of 300 ppm/°C at 4V. Standard capacitance tolerance is ±10%, and specifications include 0.18 pF case capacitance.

Feature Summary

• Silicon abrupt junction construction providing high Q and low series resistance
• RoHS compliant manufacturing process
• Gold plated terminations as standard finish

Applications

• VHF to Ku Band Tuning
• Voltage Variable Filters (VVF)
• Phase Shifters

Procurement Notes

Verify the specific ordering suffix required for the desired package style when placing orders, as the GC1500A-00 designation specifically indicates chip form. Confirm terminal finish requirements with the manufacturer if gold plating is not suitable for the application. Check for product change notifications regarding material or process updates before finalizing procurement plans.

Selection Notes

Select this component for narrow to moderate bandwidth tuning in low phase noise voltage controlled oscillators and low loss filters. Ensure the design accounts for the included 0.18 pF case capacitance in total circuit calculations. Verify that the operating frequency range aligns with the specified Q factor measurement conditions at 50 MHz.

Part Context

This part belongs to the GC1500 series of 30 Volt abrupt junction tuning varactors manufactured by Microsemi (now Microchip Technology). The series provides a large selection of capacitance values optimized for VHF through KU band frequencies. The GC1500A variant is distinctively available only in chip form, differentiating it from other series members that may offer additional package styles.

Replacement Considerations

Consult the factory for alternative terminal finishes or custom mechanical configurations. Other package styles within the GC1500 series are available upon request but require specific ordering suffixes.
