SMV1249-079LF Description

Short technical summary and product information.

The SMV1249-079LF is a silicon hyperabrupt junction varactor diode from Skyworks Solutions, part of the SMV1247-SMV1255 series. It is designed for low tuning voltage Voltage Controlled Oscillators (VCOs) in high-volume commercial systems.

 

Key electrical specifications include a reverse voltage rating of 15V, a typical capacitance of 2.8pF at Vr=4.7V and f=50MHz, and a high capacitance ratio of 12.1 (C0.3V/C4.7V). The device offers a typical Q factor of 600 at Vr=3V and f=50MHz, making it suitable for RF applications requiring low loss.

 

The SMV1249-079LF is supplied in a surface-mount SC-79 package, rated MSL Level 1 (unlimited) per JEDEC J-STD-020. It is RoHS3 compliant, lead-free (LF suffix), and halogen-free per Skyworks GreenTM definition. Operating temperature range is -55°C to 125°C.
