GCX1209-23-0/TR

Overview

The GCX1209-23-0/TR is a surface-mount variable capacitance diode from the GCX1200–23 series, manufactured by Microchip Technology. It utilizes an abrupt junction silicon design housed in a compact SOT23 package. The component provides a nominal diode capacitance of 8.2 pF and supports a maximum repetitive peak reverse voltage of 30 V. Designed for high performance, it features a minimum quality factor of 2000 and low series resistance, making it suitable for narrow to moderate frequency bandwidth applications across HF through 1500 MHz.

Feature Summary

• Abrupt junction silicon construction for high Q and low series resistance
• Compact SOT23 surface-mount packaging for commercial assembly
• Single diode configuration within the GCX1200–23 series

Applications

• Narrow to moderate frequency bandwidth circuits
• HF through 1500 MHz tunable filter designs
• RF tuning networks requiring high quality factors

Procurement Notes

Verify the specific suffix -0/TR against official Microchip documentation to confirm single-diode configuration and tape-and-reel packaging status. Ensure compatibility with RoHS Directive 2002/95/EC requirements if mandated by your project specifications. Cross-reference the part number with current datasheets to validate availability and any superseding device information before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring high Q varactors in small form factors. The 8.2 pF nominal capacitance and 30 V rating suit specific RF tuning ranges. Compare against other series members for different capacitance values or common cathode configurations if system architecture requires multiple tuned elements in a single package.

Part Context

This part belongs to the GCX1200–23 series of surface-mount varactors, which supersede earlier GC1200–23 versions. The series offers silicon abrupt junction devices optimized for high performance in limited space. The -23 designation indicates the SOT23 package type, while the -0 suffix typically denotes the single diode variant within the family.

Replacement Considerations

Consult factory resources for availability details on potential substitutes. Verify that alternative varactors match the 8.2 pF capacitance, 30 V rating, and SOT23 footprint to ensure direct interchangeability without circuit redesign.
