MMUN2214LT1G

Overview

The MMUN2214LT1G is a single NPN Bias Resistor Transistor (BRT) manufactured by onsemi. It integrates a monolithic silicon transistor with two built-in bias resistors: a series base resistor (R1) of 10 kOhms and a base-emitter resistor (R2) of 47 kOhms, resulting in a typical resistance ratio of 0.21. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. It operates within a temperature range of -55°C to +150°C and is housed in an SOT-23-3 surface-mount package. The component is AEC-Q100 qualified for automotive applications.

Feature Summary

Integrates a single NPN transistor with dual monolithic bias resistors to simplify circuit design
Eliminates external discrete components to reduce board space and assembly costs
Qualified for automotive applications under the AEC-Q100 standard

Applications

Automotive electronic systems requiring AEC-Q100 qualification
General-purpose switching circuits utilizing pre-biased logic levels
Driver stages for relays, solenoids, or small loads

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and material declarations as stated in the datasheet. Confirm that the AEC-Q100 qualification status aligns with project requirements before finalizing procurement orders.

Selection Notes

Select this component when a single NPN digital transistor with a 10 kOhm base resistor and 47 kOhemitter resistor is required. Compare the 50 V breakdown voltage and 100 mA current rating against load requirements. Consider the SOT-23-3 footprint constraints and thermal dissipation limits relative to alternative packages.

Part Context

This part belongs to the MMUN2214L series of Bias Resistor Transistors from onsemi. It serves as a direct replacement for discrete resistor-transistor networks, offering a compact solution for driving low-power loads. The 'L' suffix typically denotes the specific internal resistor configuration within the broader MMUN family.
