BB174X

Overview

The BB174X is a varactor diode from NXP USA Inc., designed for variable capacitance applications in the VHF frequency range. It features a single configuration and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a reverse voltage rating of 30 V, a forward current capacity of 20 mA, and a minimum tuning ratio of 8.45. The device has a capacitance of 2.1 pF and is housed in a DFN1006D-2 package suitable for SMD/SMT mounting.

Feature Summary

Designed for variable capacitance applications in VHF circuits
Single configuration with high tuning ratio capability
Operates reliably across extended industrial temperature ranges

Applications

VHF tuning circuits
Frequency modulation modules
RF filter adjustment networks

Procurement Notes

Verify the specific suffix designation (e.g., XX) against official NXP documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the ordering part number matches the exact electrical specifications required for the target VHF application design.

Selection Notes

Select this component based on its 30 V reverse voltage rating and 2.1 pF capacitance value for VHF designs. Consider the DFN1006D-2 package size for space-constrained PCB layouts. Verify that the operating temperature range of -55°C to +125°C meets the environmental conditions of the final assembly.

Part Context

This component belongs to the Varactor Diodes category under General Purpose Diodes. It is manufactured by NXP Semiconductors and is specifically optimized for variable capacitance functions in radio frequency and communication systems requiring stable performance in the VHF band.

Replacement Considerations

Check for direct pin-compatible substitutes with similar capacitance and reverse voltage ratings. Verify if alternative varactor diodes offer comparable tuning ratios and package dimensions for seamless integration into existing VHF circuit designs without layout modifications.
