BB202,115

Overview

The BB202 is a low-voltage variable capacitance diode fabricated in planar technology and encapsulated in the SOD523 ultra-small SMD plastic package. It features a very steep C/V curve with a capacitance ratio of at least 2.5 between 0.2 V and 2.3 V reverse bias. The device operates within a continuous reverse voltage limit of 6 V and supports junction temperatures from -55 °C to +85 °C. Electrical characteristics include a typical series resistance of 0.35 Ω at 100 MHz and a maximum reverse current of 10 nA at 6 V.

Feature Summary

• Very steep capacitance-to-voltage (C/V) curve for precise tuning applications
• Ultra-small SOD523 surface-mount package design
• Low series resistance for high-frequency performance

Applications

• Electronic tuning in FM radio systems
• Voltage Controlled Oscillators (VCO)

Procurement Notes

Verify the specific ordering code BB202,115 against the manufacturer's current product status page to confirm availability and production lifecycle stage. Ensure the selected component matches the required SOD523 package outline and pin configuration before integration into the final design.

Selection Notes

Select this component when a compact variable capacitance diode with a steep C/V characteristic is required for low-voltage circuits. Consider the 6 V reverse voltage limit and the specific capacitance values at 0.2 V and 2.3 V to ensure compatibility with the target oscillator or tuning circuit requirements.

Part Context

The BB202 belongs to NXP Semiconductors' portfolio of discrete semiconductor components, specifically categorized as a varactor or variable capacitance diode. It utilizes planar technology for fabrication and is designed for surface-mount assembly, supporting modern miniaturization trends in electronic equipment.

Replacement Considerations

Consult official substitution guides for compatible varactors with similar C/V ratios and package types. Verify that any alternative device meets the same electrical limits, particularly the 6 V reverse voltage rating and SOD523 footprint dimensions.
