Overview
The DMB2227A-7 is a complementary NPN/PNP small-signal surface mount transistor array manufactured by Diodes Incorporated. It integrates one 2N2222A-type NPN transistor and one 2N2907A-type PNP transistor within a single SOT-26 package. The NPN device supports a collector-emitter voltage of 40V, while the PNP device supports 60V. Both transistors handle a continuous collector current of 600mA with a total power dissipation of 300mW. The NPN type features a transition frequency of 300MHz, whereas the PNP type operates at 200MHz. The component utilizes epitaxial planar die construction and is designed for low-power amplification and switching applications.
Feature Summary
- Complementary pair configuration integrating NPN and PNP transistors in a single compact package
- Epitaxial planar die construction for reliable performance
- Lead-free design compliant with RoHS standards
Applications
- Low power amplification circuits
- General purpose switching applications
Procurement Notes
Verify the specific ordering suffix to confirm packaging format. The standard -7 suffix indicates tape and reel packaging containing 3000 units per reel. Confirm that the required quantity aligns with the reel size or verify if cut tape options are available from authorized distributors. Ensure the date code marking matches production requirements.
Selection Notes
Select this component when space-constrained designs require matched complementary NPN and PNP pairs. The SOT-26 package offers a smaller footprint compared to discrete components. Verify that the 40V NPN and 60V PNP voltage ratings meet circuit requirements. Consider the 300mW total power dissipation limit and thermal resistance of 417°C/W for heat management on FR-4 PCBs.
Part Context
This part belongs to the DMB2227A series of complementary small signal transistors produced by Diodes Incorporated. It serves as a surface-mount alternative to through-hole discrete transistor pairs. The device combines standard 2N2222A and 2N2907A characteristics into a unified assembly, simplifying board layout for push-pull or differential amplifier stages.
Replacement Considerations
Direct replacements include other complementary NPN/PNP arrays in SOT-26 packages such as the MMBT2222A/2907A variants from other manufacturers. Verify pinout compatibility and electrical parameter margins before substitution.
FAQ
