MMDT2222A_R1_00001

Overview

The MMDT2222A_R1_00001 is a dual surface mount NPN transistor manufactured by Panjit International Inc. It contains two electrically isolated 2N2222A transistors in an SOT-363 package. Key electrical ratings include a collector-emitter voltage of 40V, collector-base voltage of 75V, and emitter-base voltage of 6.0V. The continuous collector current is 600mA with a total power dissipation of 600mW at 25°C. Thermal resistance from junction to ambient is 625°C/W. DC current gain ranges from 35 to 300, and the gain-bandwidth product is 300MHz.

Feature Summary

• Contains two electrically-isolated NPN transistors within a single ultra-small SOT-363 package.
• Features well-matched hFE characteristics between the internal transistors.
• Complies with EU RoHS 2011/65/EU directives and utilizes halogen-free green molding compound.

Applications

• General purpose amplifier applications
• Hand-held computers
• Personal Digital Assistants (PDAs)

Procurement Notes

Verify the specific ordering suffix R1_00001 against official Panjit documentation to confirm packing type as Tape and Reel and packaging size as 7 inches. Ensure compliance requirements such as RoHS and halogen-free status are explicitly stated for the target revision. Confirm that the device marking code corresponds to M2A on the physical component.

Selection Notes

Select this component when board space is limited due to its compact SOT-363 footprint. It is suitable for portable electronics requiring dual NPN switching or amplification functions. Verify that the 600mW power dissipation rating meets thermal constraints without additional heatsinking on standard FR-4 boards.

Part Context

This part belongs to the MMDT2222A series of dual surface mount NPN transistors. It serves as a compact alternative to discrete single transistors, integrating two matched devices into one package. The series is designed for high-density circuit layouts common in modern consumer electronics.

Replacement Considerations

Direct substitutes must match the SOT-363 package and provide dual electrically isolated NPN transistors. Verify pinout compatibility and ensure equivalent electrical parameters for VCEO, IC, and hFE before implementation.
