GC1500A-02

Overview

The GC1500A-02 is a silicon abrupt junction tuning varactor diode from the GC1500 series, designed for VHF to Ku Band applications. It features a minimum breakdown voltage of 30V at 10 uA and a maximum leakage current of 0.02 uA at 25 Volts and 25°C. The device offers a capacitance (CT) of 4 pF ±10% measured at -4V, with a minimum quality factor of 5000 at -4V and 50 MHz. It exhibits a minimum capacitance ratio of 4.2 between -4V and 0V. Operating temperature ranges from -55°C to +125°C, with storage temperatures up to +150°C. The thermal coefficient of capacitance is 300 ppm/°C at 4 Volts.

Procurement Notes

Verify the specific ordering suffix required for the desired package style when placing orders, as standard availability may vary by configuration. Confirm RoHS compliance status and terminal finish specifications directly with the manufacturer or authorized distributors prior to procurement to ensure alignment with project requirements.

Selection Notes

Select this component based on the required capacitance value and operating frequency range within the VHF to Ku Band spectrum. Ensure the design accommodates the 30V breakdown voltage limit and verify that the package style matches the PCB layout constraints, noting that the -02 suffix indicates a specific non-hermetic chip form factor.
