MMUN2234LT1G

Overview

The MMUN2234LT1G is a single NPN Bias Resistor Transistor (BRT) manufactured by onsemi. It integrates a monolithic bias network consisting of a series base resistor and a base-emitter resistor with an NPN transistor. The device features a typical input resistance of 22 kOhms and a typical resistor ratio of 0.47. Key electrical ratings include a collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 400 mW. The minimum DC current gain (hFE) is 80. It operates within a temperature range of -55°C to +150°C and is housed in an SOT-23-3 package.

Feature Summary

Integrates a single NPN transistor with a monolithic bias network comprising two resistors to replace discrete components.
Reduces printed circuit board space and component count by eliminating external biasing resistors.
Simplifies circuit design through built-in biasing capabilities.

Applications

General-purpose switching applications
Driver circuits for logic outputs
Replacement for discrete transistor and resistor networks

Procurement Notes

Verify the specific suffix LT1G against official datasheets to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and halogen-free certification requirements prior to procurement. Check for automotive qualification markings if AEC-Q101 standards are required for the target application environment.

Selection Notes

Select this component when a compact NPN switch requires integrated biasing. Ensure the 22 kOhm input resistance matches the driving source impedance. Verify that the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Confirm that the SOT-23-3 package fits the available footprint constraints.

Part Context

This part belongs to the MMUN2234L series of digital transistors. The series is designed to simplify designs by combining a transistor and bias resistors into one package. Variants within the series differ primarily in resistor values and packaging options, such as SOT-23 or SC-59.
