SMV1263-074LF

Overview

The SMV1263-074LF is a silicon hyperabrupt junction tuning varactor diode from Skyworks Solutions Inc., designed for 3 V platforms. It features a SC-70 (Green) package with an inductance of 1.4 nH and marking EN3. The device operates within a temperature range of -55°C to +125°C. Key electrical specifications include a maximum reverse voltage of 20 V, a typical capacitance ratio of 2.5 at C0.5/C2.5, and a series resistance of 1.2 Ω at 900 MHz. At 1 MHz, the capacitance is typically 6.7 pF at 0.5 V reverse bias and 2.6 pF at 2.5 V reverse bias.

Feature Summary

• High capacitance ratio achieved at low reverse voltages
• Packages rated MSL1 and 260 °C per JEDEC J-STD-020

Applications

• Low-noise and wideband UHF and VHF VCOs
• High-volume, low-cost battery-powered tuning circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status via official documentation. Check current availability as manufacturing status may change. Ensure proper ESD handling precautions are followed during storage and assembly to prevent damage.

Selection Notes

Select this component for designs requiring high capacitance ratios at low reverse voltages. Suitable for wireless systems operating up to and over 2.5 GHz. Verify package compatibility with SC-70 footprint. Consider thermal management within the specified operating temperature range.

Part Context
