CPINUC5206-HF

RF Diode Overview

The CPINUC5206-HF is a PIN diode manufactured by Comchip Technology, designed for RF applications. It features a maximum reverse voltage of 180V and a power dissipation rating of 300mW. The component is housed in an SOD-523F package with two pins. Key electrical specifications include a capacitance of 0.22pF measured at 40V and 100MHz. This low capacitance value supports high-frequency performance by minimizing insertion loss and maximizing isolation in switching circuits.

RF Diode Procurement Notes

Verify the specific datasheet version from Comchip Technology to confirm exact test conditions for capacitance and leakage current. Ensure the SOD-523F package dimensions align with the target PCB footprint. Confirm RoHS compliance status if required by assembly standards. Cross-reference the part number suffix to ensure no functional variations exist between manufacturing batches or revisions.

RF Diode Selection Notes

Select this component when a compact RF switch requires low parasitic capacitance to maintain signal integrity at high frequencies. The 180V rating provides adequate headroom for moderate voltage swings. Consider the 300mW power limit for thermal management in dense layouts. Compare against alternative PIN diodes if higher current handling or different package sizes are necessary for the specific application constraints.

RF Diode Part Context

This device belongs to Comchip Technology's lineup of surface-mount RF components. It utilizes the SOD-523F form factor, which allows for automated pick-and-place assembly. The product falls under the broader category of semiconductor diodes specialized for microwave and radio frequency engineering. It serves as a passive control element within active RF front-end architectures.

RF Diode Replacement Considerations

Direct substitutes must match the 180V reverse voltage, 300mW power rating, and SOD-523F package. Verify that any replacement exhibits comparable capacitance values near 0.22pF at 40V/100MHz to prevent impedance mismatch. Check for identical pinout configurations to ensure board compatibility without redesign.
