Overview
The MMDT4146-7-F is a complementary NPN/PNP small-signal surface mount transistor manufactured by Diodes Incorporated. It integrates two transistors in a single SOT-363 (SC-88) package with six pins. The device supports a maximum DC collector current of 200 mA. Electrical ratings include a collector-emitter voltage (VCEO) of 25 V and a collector-base voltage (VCBO) of 30 V. The emitter-base voltage (VEBO) is rated at 5 V. The component is designed for surface mounting applications.
Feature Summary
- Integrates complementary NPN and PNP bipolar junction transistors within a compact SOT-363 package to reduce board space.
- Provides isolated transistor configuration suitable for general-purpose switching and amplification tasks.
Applications
- General-purpose signal switching circuits
- Complementary amplifier stages
- Digital logic interface buffers
Procurement Notes
Verify the specific manufacturer designation, as the component is associated with both DiodesZetex and Diodes Incorporated branding. Confirm the package type matches the required SOT-363 footprint. Ensure the electrical parameters align with the circuit design requirements before finalizing procurement decisions.
Selection Notes
Select this component when a dual complementary transistor solution is required in a minimal footprint. The 200 mA current rating and 25 V voltage rating define the operational limits. Verify that the thermal dissipation capabilities of the SOT-363 package are sufficient for the intended application load.
Part Context
This part belongs to the MMDT series of complementary small-signal transistors from Diodes Incorporated. Similar devices in this family include the MMDT2227 and MMDT3946, which offer different voltage and current characteristics while maintaining comparable packaging formats for system integration flexibility.
Replacement Considerations
Potential substitutes include the MMDT4146 without the suffix or other complementary pairs in SOT-363 packages such as the MMDT2227. Verify pinout compatibility and electrical specifications before substitution.
