MA27V0500L

Overview

The MA27V05 is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It operates with a maximum reverse voltage of 10 V and features a junction temperature rating of 125 °C. The device provides a typical diode capacitance of 20.5 pF at 1 V reverse bias and 4.1 pF at 4 V, yielding a capacitance ratio of 4.7. It exhibits low series resistance of 0.65 Ω at 470 MHz and minimal reverse current of 10 nA at 10 V. The component is housed in an SSS-Mini type package.

Feature Summary

• Good linearity and large capacitance-ratio in CD-VR relation
• Small series resistance rD
• SSS-Mini type package allowing downsizing of equipment

Applications

• Voltage-controlled oscillators (VCO)

Procurement Notes

Verify the current lifecycle status on the manufacturer's official website before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the RoHS Directive compliance meets your environmental requirements. Ensure the SSS-Mini package dimensions align with your PCB layout constraints.

Selection Notes

Select this component when designing circuits requiring high capacitance ratios and good linearity between capacitance and reverse voltage. The low series resistance makes it suitable for RF applications around 470 MHz. Verify that the operating environment stays within the specified -55 to +125 °C storage temperature range.
