MA27V1200L

Overview

The MA27V1200L is a silicon epitaxial planar variable capacitance diode designed for voltage-controlled oscillator (VCO) applications. It operates with an 8 V maximum reverse voltage and a junction temperature rating of 125 °C. The device provides a typical capacitance of 3.90 pF at 1 V reverse bias and 2.14 pF at 4 V reverse bias, measured at 1 MHz. It achieves a capacitance ratio of 1.90 between these voltages. The series resistance is specified as 0.35 Ω at 470 MHz. The component utilizes the SSSMini2-F1 package, measuring 1.0 mm by 0.6 mm with a height of 0.52 mm.

Procurement Notes

Verify the current lifecycle status directly with Panasonic or authorized distributors before procurement. The official documentation indicates this product falls under maintenance or discontinued categories. Confirm availability of the specific SSSMini2-F1 packaging format and ensure compliance with RoHS Directive requirements during sourcing.

Selection Notes

Select this component when designing circuits requiring a small footprint and high-frequency performance. Ensure the operating reverse voltage remains within the 8 V limit to prevent breakdown. Verify that the required capacitance range aligns with the 1.97 pF to 3.90 pF specifications at standard test frequencies.

Part Context

This part belongs to the MA27V12 series of variable capacitance diodes manufactured by Panasonic Electronic Components. It shares the same functional characteristics and package dimensions as other variants within the MA27V12 family, differing primarily in suffix designations related to packaging or testing conditions.

Replacement Considerations

Consult the official Panasonic replacement guide for verified substitutes. Cross-reference electrical parameters such as capacitance ratio and series resistance to ensure compatibility with existing VCO designs without modifying the circuit layout.
