UMG2NTR

Overview

The UMG2NTR is a dual NPN digital transistor manufactured by ROHM Semiconductor, housed in the UMT5 (SOT-353) surface-mount package. It integrates two NPN transistors with built-in bias resistors to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device features a maximum power dissipation (PD) of 150 mW and operates within a temperature range of -55°C to +150°C. Input resistance (R1) options are available from 1 kΩ to 47 kΩ, while emitter-base resistance (R2) ranges from 1 kΩ to 47 kΩ.

Feature Summary

• Integrates two NPN transistors with internal bias resistors in a compact SMD package
• Eliminates external resistor requirements for base drive circuits
• Supports high-temperature operation up to 150°C junction temperature

Applications

• Differential amplifier circuits
• High-frequency crystal oscillator starters
• General-purpose digital switching applications

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct resistor values and polarity. Confirm RoHS compliance status and automotive qualification requirements if applicable to the target application. Check lead times and packaging quantities directly with authorized distributors or the manufacturer.

Selection Notes

Select based on required input resistance values ranging from 1 kΩ to 47 kΩ for R1 and R2. Ensure the 50 V voltage rating and 100 mA current capacity meet circuit demands. Consider the UMT5 package size for space-constrained designs requiring dual NPN functionality.

Part Context

This component belongs to ROHM's UMG series of complex digital transistors. These devices combine multiple transistors and resistors into single packages to reduce board space and assembly complexity. The UMG2NTR specifically provides a dual NPN solution suitable for replacing discrete transistor-resistor networks.

Replacement Considerations

Equivalent single-transistor parts include DTC144E. Verify pin compatibility and electrical characteristics before substitution. Alternative dual NPN digital transistors from other manufacturers may require schematic adjustments due to differing internal resistor configurations.
