MA2S30400L

Overview

The MA2S30400L is a silicon epitaxial planar variable capacitance diode designed for Voltage Controlled Oscillator (VCO) applications. It features a single-diode configuration housed in an SS-Mini type package, which facilitates equipment downsizing and automatic insertion via taping. The device operates with a maximum reverse voltage of 30 V and a junction temperature rating of 150 °C. Key electrical characteristics include a typical diode capacitance of 8.3 pF at 4 V and 1 MHz, achieving a capacitance ratio of 3.0 between 1 V and 4 V bias points. The series resistance is specified as low as 1.0 Ω at 100 MHz.

Feature Summary

• Good linearity and large capacitance-ratio in the C_D-V_R relation
• Small series resistance r_D
• SS-Mini type package allowing downsizing of equipment and automatic insertion through the taping package

Applications

• Voltage Controlled Oscillators (VCO)
• General electronic equipment
• Communications equipment
• Measuring instruments
• Household appliances

Procurement Notes

Verify current lifecycle status before design-in, as this component may be discontinued or subject to maintenance schedules. Confirm that the latest Panasonic datasheet matches required specifications. Ensure compatibility with RoHS Directive standards. Check for authorized distributors if standard supply channels are unavailable due to end-of-life status.

Selection Notes

Select based on required capacitance tuning range and linearity for VCO designs. Consider the SS-Mini package dimensions for PCB layout constraints. Verify operating temperature ranges against environmental conditions. Evaluate series resistance impact on circuit Q-factor at target frequencies.

Part Context

The MA2S30400L belongs to the MA2S304 family of silicon epitaxial planar variable capacitance diodes manufactured by Panasonic Industry. These components are engineered for RF applications requiring stable capacitance variation with reverse voltage. The specific suffix '00L' denotes the packaging and marking configuration within this product line.

Replacement Considerations

Check Panasonic's official replacement list for the MA2S304 series. Verify pinout compatibility and package dimensions (SC-79/SSMini2-F2). Compare electrical parameters such as capacitance ratio and series resistance to ensure circuit performance is maintained.
