SMMUN2214LT1G

Overview

The SMMUN2214LT1G is a single NPN digital transistor from the MMUN2214L series, manufactured by onsemi. It integrates an NPN bipolar junction transistor with built-in bias resistors in a surface-mount SOT-23-3 package. Key electrical parameters include a collector-emitter maximum voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistor value of 10 kOhms and a typical resistor ratio of 0.21. It operates within a temperature range of -55°C to +150°C and holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Integrates an NPN transistor with monolithic bias resistors to simplify circuit design
• AEC-Q100 qualified for automotive electronics reliability standards
• Operates over an extended industrial temperature range up to +150°C

Applications

• Automotive switching circuits requiring AEC-Q100 compliance
• General-purpose digital switching applications
• Interface circuits between logic gates and loads

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required packaging format, such as cut tape or reel, as these affect handling procedures. Ensure the procurement documentation includes relevant quality certifications and material declarations to meet regulatory requirements for the intended application environment.

Selection Notes

Select this component when a single NPN configuration with a 10 kOhm base resistor is required. The SOT-23-3 package offers space efficiency for surface-mount designs. Consider the 50 V voltage rating and 100 mA current capacity against load requirements. Verify thermal management needs given the 246 mW power dissipation limit in the specified package type.

Part Context

This part belongs to the MMUN2214L family of pre-biased transistors. It serves as a compact alternative to discrete resistor-transistor networks. The 'S' prefix indicates a specific manufacturing variant or traceability code within the standard MMUN2214L product line offered by onsemi.

Replacement Considerations

Direct functional substitutes include the MMUN2214LT1G (PNP version) for complementary configurations. Other compatible parts within the same series may offer different resistor ratios but share identical pinouts and electrical ratings.
