DMMT3904W-AU_R1_000A1

Overview

The DMMT3904W-AU_R1_000A1 is a dual NPN bipolar junction transistor array manufactured by Panjit International Inc. Housed in a surface-mount SOT-363 package, this component features an epitaxial silicon planar design optimized for general-purpose switching applications. It provides a collector-emitter voltage rating of 40V and a continuous collector current capacity of 200mA per transistor. The device supports a maximum power dissipation of 225mW and exhibits a transition frequency exceeding 300MHz under specified test conditions. This matched pair configuration ensures consistent electrical characteristics between the two internal transistors.

Feature Summary

• Dual NPN matched pair configuration within a single compact surface-mount package
• Epitaxial silicon planar construction for reliable switching performance
• High transition frequency capability suitable for fast signal processing

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Low-power amplifier stages requiring matched pairs

Procurement Notes

Verify the specific ordering suffix against official Panjit documentation to confirm package type and tape-and-reel specifications. Ensure that the requested variant matches the required thermal and electrical ratings for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when a matched dual NPN transistor pair is required in a minimal footprint. The SOT-363 package offers space efficiency compared to discrete solutions. Consider the 40V breakdown voltage and 200mA current limits to ensure adequate headroom for the intended load conditions. Verify compatibility with automated pick-and-place equipment due to the small surface-mount form factor.

Part Context

This part belongs to the MMBT3904 series family of general-purpose NPN switching transistors. While similar to single-transistor variants like the MMBT3904, this specific model integrates two matched units into one package. The AU suffix typically denotes environmental compliance attributes such as halogen-free molding compounds. It serves as a direct replacement for other dual NPN arrays in existing designs requiring matched characteristics.
