MMDT4403_R1_00001

Overview

The MMDT4403_R1_00001 is a dual PNP general-purpose switching transistor manufactured by Panjit International Inc. It features an epitaxial silicon planar design housed in an SOT-363 plastic package. The device supports a collector-emitter voltage of -40V and a continuous collector current of -600mA, with a maximum power dissipation of 225mW at 25°C ambient temperature. Key electrical parameters include a DC current gain ranging from 20 to 300 depending on the operating point, and a transition frequency of 200MHz. The component complies with EU RoHS 2011/65/EU directives and utilizes halogen-free green molding compound.

Feature Summary

• Dual PNP configuration within a single compact SOT-363 package for space-efficient circuit designs
• Epitaxial silicon planar construction optimized for high-speed switching applications
• Halogen-free green molding compound compliant with IEC61249 standards

Applications

• General-purpose signal switching circuits
• Complementary pairs with NPN transistors in amplifier stages
• Low-voltage logic interface applications

Procurement Notes

Verify the ordering suffix against official documentation to confirm packing specifications. The suffix indicates tape and reel packaging on a 13-inch reel. Confirm compliance requirements such as RoHS status and lead-free solderability per MIL-STD-750 Method 2026 before procurement. Ensure the lot number is recorded for tracking purposes upon receipt.

Selection Notes

Select this component when a dual PNP configuration is required in a small outline package. Verify that the -40V collector-emitter voltage and -600mA current ratings meet the specific circuit demands. Consider the thermal resistance of 625°C/W and the 225mW power dissipation limit for proper heat management in the final assembly.

Part Context

This part belongs to the MMDT4403 series of dual PNP transistors produced by Panjit International Inc. It serves as a complementary counterpart to NPN dual transistors in balanced circuit topologies. The R1 suffix specifically denotes tape and reel packaging on a 13-inch reel, distinguishing it from other packaging variants like bulk or tube formats.

Replacement Considerations

Direct replacements must match the SOT-363 footprint and dual PNP configuration. Verify that substitute components offer equivalent VCEO, IC, and hFE characteristics. Ensure the alternative parts support the same switching speeds and thermal limits for reliable operation in existing designs.
