MMDT3906-TPQ2

Overview

The MMDT3906-TPQ2 is a dual PNP bipolar junction transistor (BJT) array manufactured by Micro Commercial Components. It integrates two electrically isolated transistors within an SOT-363 surface-mount package. The device supports a maximum collector current of 200 mA and withstands collector-emitter and collector-base voltages of 40 V, with an emitter-base voltage rating of 5 V. Key electrical parameters include a transition frequency of 250 MHz, a power dissipation capacity of 200 mW, and a DC current gain range from 30 to 300. It operates reliably across a temperature range of -55°C to +150°C.

Feature Summary

• Dual configuration containing two electrically isolated PNP switching transistors
• Ultra-small SOT-363 surface-mount package design for board space efficiency
• Epitaxial planar die construction for robust performance

Applications

• General-purpose amplifier circuits
• Low-power signal switching applications
• Portable electronic devices where space is limited

Procurement Notes

Verify the specific suffix Q2 against official MCC documentation to confirm its exact meaning regarding packaging or qualification status. Ensure the component matches the standard MMDT3906 electrical specifications if no distinct functional changes are documented. Cross-reference datasheets to validate availability and compliance details before procurement.

Selection Notes

Select this component when a dual PNP configuration is required in a compact footprint. It serves as a suitable alternative to single-transistor solutions requiring two units. Verify that the 40V voltage rating and 200mA current limits align with the circuit requirements. Consider the SOT-363 package dimensions for PCB layout constraints.

Part Context

This part belongs to the MMDT3906 series of dual PNP small-signal transistors. It shares core characteristics with other variants like the MMDT3906HE3-TP but may differ in packaging or qualification specifics due to the unique suffix. It is designed for portable applications requiring high-density mounting.

Replacement Considerations

Standard equivalents include the MMDT3906 from Panjit or Diodes Incorporated. Verify pinout compatibility and thermal characteristics when substituting.
