MAVR-001340-1146FT

Overview

The MAVR-001340-1146FT is a silicon hyperabrupt varactor diode from the MAVR-0013xx series, designed for low voltage and low series resistance applications. It features a common cathode configuration in an SC-70 (3L) plastic package. Key electrical specifications include a nominal capacitance of 18 pF at zero bias, with a minimum breakdown voltage of 12 V and a maximum reverse leakage current of 100 nA at 10 V. The device exhibits a typical capacitance ratio of 3.40 between 0.5 V and 3.0 V tuning voltages, and a maximum series resistance of 0.85 Ω at 2.0 V.

Procurement Notes

Verify component authenticity through authorized MACOM distributors or direct channels. Confirm RoHS compliance status and lead-free packaging details against the latest datasheet revision. Ensure ordering suffixes match the required package style and configuration to prevent assembly errors during procurement.

Selection Notes

Select this part when a common cathode topology is required for differential or balanced circuit applications. The 18 pF nominal capacitance suits specific frequency ranges within the UHF spectrum. Evaluate the 0.85 Ω maximum series resistance against insertion loss requirements in the target RF path.

Part Context

This component belongs to the MAVR-0013xx series of silicon hyperabrupt varactors. The series offers various capacitance values and package options, including single diodes in SOD-323/SC-79 and common cathode pairs in SC-70. The -1146FT suffix specifically denotes the SC-70 3-lead package with common cathode configuration.

Replacement Considerations

Direct substitutes within the same series include MAVR-001320-1146FT, MAVR-001330-1146FT, and MAVR-001350-1146FT. These share identical packaging and configuration but differ in nominal capacitance values ranging from 9.5 pF to 48 pF.
