Overview
The MMDT3946-TP is a complementary NPN/PNP small signal surface mount transistor array manufactured by Micro Commercial Components. It integrates one 3904-type NPN and one 3906-type PNP transistor in an SOT-363 package. The device features a maximum continuous collector current of 200 mA and a power dissipation rating of 200 mW. Electrical characteristics include a collector-emitter breakdown voltage of 40 V, a transition frequency of 300 MHz for the NPN element, and a DC current gain (hFE) ranging from 100 to 300 at specific test conditions.
Feature Summary
- Complementary pair configuration combining NPN and PNP elements
- Epitaxial planar die construction for reliability
- Halogen-free green device compliant with environmental standards
Applications
- Low power amplification circuits
- General purpose switching applications
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the -TP suffix indicates RoHS compliance and tape-and-reel packaging containing 3,000 units per reel. Ensure storage conditions align with Moisture Sensitivity Level 1 requirements before soldering.
Selection Notes
Select this component for designs requiring a matched complementary pair in a compact SOT-363 footprint. Consider the 200 mW power dissipation limit and thermal resistance when determining heat management needs. Verify that the 40 V breakdown voltage meets the circuit's operating requirements.
Part Context
This part belongs to the MMDT3946 series of small signal transistors. It serves as a surface-mount alternative to discrete through-hole transistors, consolidating two devices into one package to save board space. The internal structure utilizes epitaxial planar technology common in modern semiconductor manufacturing.

FAQ
What is the marking code on the MMDT3946-TP package?
The marking code on the package is K46.
What are the delay and rise times for the NPN transistor?
Both the delay time (td) and rise time (tr) for the NPN transistor are specified as 35 ns under standard test conditions.
Does the 'P' suffix in related part numbers indicate a functional change?
No, the 'P' suffix designates RoHS compliance only and does not alter the electrical function or specifications of the device.
