BB207,215

Overview

The BB207,215 is a dual varactor diode manufactured by NXP USA Inc., housed in an SOT-23 (TO-236AB) surface-mount package. It features a common cathode configuration with two independent varactor elements sharing a single cathode terminal. The device supports a maximum peak reverse voltage of 15 V and operates within a junction temperature range of -55°C to +125°C. At 8 V reverse bias and 1 MHz frequency, the capacitance is specified as 26.3 pF. The component exhibits a minimum tuning ratio of 2.6, with a typical capacitance ratio of 3.3 measured at C1/C7.5 conditions.

Feature Summary

• Dual varactor structure with common cathode configuration for compact circuit integration
• Surface-mount SOT-23 packaging suitable for automated assembly processes
• Wide operating temperature range supporting harsh environmental conditions

Applications

• Frequency modulation circuits requiring variable capacitance control
• Voltage-controlled oscillator (VCO) designs for RF signal generation
• Tuning networks in radio frequency receivers and transmitters

Procurement Notes

Verify the specific ordering suffix against official NXP documentation to confirm tape-and-reel specifications or cut-tape availability. Confirm current lifecycle status, as distribution sources indicate this part may be discontinued. Ensure compatibility with existing PCB footprints and soldering profiles before finalizing procurement orders.

Selection Notes

Select this component when a dual varactor solution with common cathode topology is required in a minimal footprint. Compare the 26.3 pF capacitance value and 15 V rating against circuit requirements. Evaluate the tuning ratio performance relative to alternative NXP series such as the BB201 if different capacitance characteristics are needed.

Part Context

The BB207 belongs to NXP's broader portfolio of silicon varactor diodes designed for RF and microwave applications. It shares the SOT-23 form factor with related parts like the BB201, offering designers standardized mounting options. These components are integral to tuning circuits where precise capacitance variation via reverse bias voltage is essential for frequency stability.

Replacement Considerations

Public sources list the BB201,215 as a related variant within the same family. Verify if the BB201's distinct capacitance (25.5 pF) and higher tuning ratio (3.8) meet the design requirements as a functional substitute.
