MA3J142KGL

Single Diodes Overview

The MA3J142KGL is a silicon epitaxial planar switching diode from Panasonic, designed for high-density mounting in electronic circuits. It features a short reverse recovery time and low terminal capacitance. The device operates with a maximum reverse voltage of 80 V and a forward current rating of 100 mA. Key electrical characteristics include a typical reverse recovery time of 3 ns and a terminal capacitance of 2 pF at 1 MHz. It utilizes an SMini3-F1 package (EIAJ: SC-79) with three terminals, where pin 1 serves as the cathode and pin 3 as the anode.

Single Diodes Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required specifications before integration into designs. Check official sources for the latest lifecycle status, as maintenance or discontinuation notices may affect long-term availability. Ensure compliance with RoHS directives if applicable to your manufacturing standards.

Single Diodes Selection Notes

Select this component for applications requiring fast switching speeds within low-voltage environments. The 80 V reverse voltage rating limits its use to low-power signal processing rather than high-voltage power supplies. Consider the SMini3-F1 footprint constraints during PCB layout planning. Evaluate thermal management requirements against the specified junction temperature range for reliable operation under varying ambient conditions.

Single Diodes Part Context

This component belongs to the MA3J142 series, which includes variants like the MA3J142A. Both share similar physical dimensions but differ in electrical performance metrics such as reverse recovery time and capacitance. The series represents Panasonic's standard offering for compact, high-speed rectification tasks in consumer and industrial electronics.

Single Diodes Replacement Considerations

Direct substitutes are not explicitly listed in the provided documentation. Designers should evaluate other silicon epitaxial planar diodes with comparable 80 V ratings and similar package footprints. Verify that any alternative meets the specific reverse recovery time and capacitance requirements of the original design.
