MMDT4413_R1_00001

Overview

The MMDT4413 is a complementary NPN/PNP small-signal surface-mount transistor manufactured by Panjit International Inc. It integrates one 4401-type NPN and one 4403-type PNP transistor within an ultra-small SOT-363 plastic package. The device features epitaxial planar die construction and is designed for low-power amplification and switching applications. Maximum ratings include a collector-emitter voltage of 40V, a continuous collector current of 200mA, and a total power dissipation of 225mW at 25°C ambient temperature. The component complies with EU RoHS 2011/65/EU directives and utilizes a green molding compound that is halogen-free.

Procurement Notes

Verify the specific ordering suffix to confirm packaging type and compliance status. The _R1_00001 suffix indicates Tape and Reel packing on a 7-inch reel with RoHS compliance. Confirm the marking code M6A matches the physical component received. Ensure the lot number is recorded for tracking purposes as per manufacturer guidelines.

Selection Notes

Select this component when a matched complementary NPN/PNP pair is required in a minimal footprint. The SOT-363 package limits total power dissipation to 225mW, necessitating careful thermal management. Verify that the 40V breakdown voltage and 200mA current rating meet the circuit requirements. Consider the gain bandwidth product and saturation voltages for high-speed or low-voltage drop performance needs.

Part Context

This part belongs to the family of complementary small-signal transistors produced by Panjit International Inc. It serves as a surface-mount alternative to through-hole complementary pairs, facilitating automated assembly. The internal structure combines distinct NPN and PNP elements, allowing for push-pull configurations or differential stages within a single compact housing.

Replacement Considerations

Direct replacements must match the SOT-363 package and complementary NPN/PNP configuration. Verify pinout compatibility and electrical parameters such as V(BR)CEO and hFE ranges.
