Overview
The GCX1206-23-0/TR is a single silicon varactor diode manufactured by Microchip Technology. It features a surface-mount SOT-23-3 package and supports a maximum reverse voltage of 30 V. The device exhibits a capacitance of 2.7 pF and a minimum tuning ratio of 3.7 under specified test conditions. It operates within a temperature range of -55 °C to +125 °C. The component is non-hermetic, plastic-encapsulated, and supplied in tape and reel packaging with a quantity of 1000 units per reel.
Feature Summary
- Single-channel silicon varactor diode design for frequency tuning applications
- Surface-mount construction utilizing the compact SOT-23-3 package format
- Non-hermetic plastic encapsulation suitable for standard SMT assembly processes
Applications
- Voltage-controlled oscillator (VCO) circuits
- Frequency synthesizer phase-locked loops
- RF filter tuning networks
Procurement Notes
Verify the specific suffix /TR against official Microchip documentation to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact electrical parameters required for the target application. Cross-reference the datasheet revision date to confirm compliance with current RoHS3 standards and material declarations before finalizing procurement orders.
Selection Notes
Select this component when a single varactor with a 30 V reverse voltage rating is required in an SOT-23-3 footprint. The 2.7 pF capacitance and 3.7 tuning ratio define its performance envelope. Confirm that the -55 °C to +125 °C operating temperature range aligns with the environmental constraints of the intended electronic system design.
Part Context
This part belongs to the Microchip Technology GCX series of silicon varactor diodes. These components are designed for high-frequency signal processing where variable capacitance is necessary for circuit adjustment. The series utilizes standard semiconductor manufacturing processes to provide reliable performance in consumer and industrial electronics requiring precise frequency control.
Replacement Considerations
Consult official Microchip substitution guides or distributor cross-reference tools for verified equivalent parts. Do not assume functional compatibility based solely on package similarity. Verify that any alternative component meets the same 30 V reverse voltage and 2.7 pF capacitance specifications.
