DMMT2907A-7

Overview

The DMMT2907A-7 is a dual PNP small signal transistor manufactured by Diodes Incorporated, housed in an SOT-26 surface-mount package. It features a collector-emitter voltage (VCEO) of -60 V and a continuous collector current (IC) of -600 mA, with a peak pulsed current capability of -1 A. The device operates within a temperature range of -55°C to +150°C and dissipates up to 1.28 W at 25°C ambient. Electrical characteristics include a DC current gain (hFE) ranging from 75 to 300, a transition frequency (fT) of 307 MHz, and a saturation voltage (VCE(sat)) of -1.6 V at -500 mA. It meets AEC-Q101 standards for high reliability.

Feature Summary

• Dual PNP transistors integrated into a single SOT-26 package to reduce footprint compared to two separate SOT-23 devices.
• Epitaxial planar die construction designed for low power amplification and switching applications.
• Qualified to AEC-Q101 standards for automotive and high-reliability environments.
• Totally lead-free, fully RoHS compliant, and halogen and antimony free.

Applications

• Low power amplification circuits
• General purpose switching applications
• Automotive electronics requiring AEC-Q101 qualified components

Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the 3,000-unit reel quantity and 7-inch tape width as documented in the manufacturer's ordering information. Confirm that the 'Green' device designation aligns with required environmental compliance specifications for bromine, chlorine, and antimony content limits before finalizing procurement orders.

Selection Notes

Select this component when space constraints require two PNP transistors in a compact SOT-26 footprint instead of discrete SOT-23 packages. Ensure the application demands a -60 V rating and -600 mA continuous current. Verify thermal management requirements against the 1.28 W power dissipation limit and derating curves for the intended operating environment.

Part Context

This part belongs to the DMMT2907 series of dual PNP transistors. It serves as a complementary or alternative solution to single-transistor configurations like the MMST2907A, offering integrated functionality in a smaller area. The device is distinct from the NPN counterpart PMBT2222 and other variants in the general-purpose transistor family.

Replacement Considerations

Direct pin-compatible replacements may include other dual PNP transistors in SOT-26 packages, such as the DMMT2907 without the 'A' suffix if electrical tolerances allow. Verify that any substitute matches the -60 V rating, -600 mA current, and AEC-Q101 qualification if automotive reliability is required.
