Applications

• Frequency modulation circuits
• Voltage-controlled oscillators
• RF tuning networks

Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm component status as the part may be discontinued or subject to design changes. Ensure compatibility with existing PCB footprints and soldering profiles before procurement.

Selection Notes

Select this component when a dual varactor with a 15 V rating and approximately 25.5 pF initial capacitance is required. Compare the 3.8 capacitance ratio against circuit requirements for tuning range. Verify that the SOT-23 package dimensions fit the mechanical constraints of the target assembly.

Part Context

This component belongs to the BB2xx series of silicon varactor diodes designed for RF applications. These devices are typically used where variable capacitance is needed for frequency adjustment in communication systems. The BB200 variant specifically targets applications requiring moderate capacitance values and standard tuning ratios.

Replacement Considerations

Check for direct substitutes within the BB2xx family, such as the BB201,215 or BB207,215, which share similar packaging but differ in capacitance and ratio specifications. Ensure any replacement matches the 15 V rating and SOT-23 form factor.
