BB182LX,315

Overview

The BB182LX,315 is a silicon variable capacitance diode designed for VHF band applications. It utilizes planar technology and is housed in an ultra-small SOD523 (SC-79) plastic surface-mount package with two pins. The device features a nominal junction capacitance of 57 pF at zero bias and a minimum breakdown voltage of 32 V. It offers a minimum capacitance ratio of 20.6 and operates within a temperature range of -55 °C to 125 °C. The component is lead-free, RoHS compliant, and classified under EAR99.

Feature Summary

• High linearity performance suitable for precision RF tuning
• Excellent matching capability achieved through direct assembly procedures
• Ultra-small plastic SMD package for compact board layouts

Applications

• Electronic tuning in VHF television tuners (Band A up to 160 MHz)
• Voltage controlled oscillators (VCO)

Procurement Notes

Verify the specific suffix '315' against official NXP documentation to confirm reel quantity or tape-and-reel specifications. Ensure the SC-79 package designation matches the required footprint. Confirm lead-free status and RoHS compliance requirements align with target manufacturing standards before finalizing orders.

Selection Notes

Select this component when high linearity and tight capacitance matching are critical for VHF frequency stability. The SOD523 package is ideal for space-constrained designs requiring low series resistance. Consider the 32 V breakdown voltage limit when designing circuits with higher reverse bias potentials.
