BB178,115

Overview

The BB178,115 is a varactor diode manufactured by NXP Semiconductors. It is housed in an SC-79-2 surface-mount package and operates within a temperature range of -55°C to +125°C. Key electrical parameters include a reverse voltage (Vr) of 32 V and a capacitance of 34.65 pF. The device features a single configuration with a minimum tuning ratio of 13.5, tested under conditions of 1 V / 28 V.

Feature Summary

• Provides variable capacitance for RF tuning applications
• Designed for surface-mount technology integration
• Operates reliably across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix against official documentation, as the BB178,115 variant may differ from the commonly referenced BB178,135. Confirm availability status directly with authorized distributors or the manufacturer, as lead times and stock levels fluctuate. Ensure compliance with RoHS directives and check for any regional distribution restrictions before placing orders.

Selection Notes

Select this component when a 32 V reverse voltage rating and approximately 34.65 pF capacitance are required for RF tuning. The SC-79-2 package suits compact surface-mount designs. Verify that the 13.5 minimum tuning ratio meets the specific frequency sweep requirements of the target application circuit.

Part Context

This part belongs to the BB178 series of varactor diodes from NXP Semiconductors. Variants such as BB178,135 share similar electrical characteristics but may differ in packaging quantities or tape specifications. The series is designed for general-purpose RF tuning applications requiring stable capacitance variation over voltage.

Replacement Considerations

Publicly confirmed substitute part numbers for the BB178,115 were not identified in available documentation. Engineers should consult official replacement guides or contact NXP Semiconductors directly for validated cross-reference data.
