UMG5NTR

Overview

The UMG5NTR is a dual NPN pre-biased transistor array manufactured by ROHM Semiconductor. It integrates two NPN transistors with built-in biasing resistors within a compact SOT-353 (UMT5) surface-mount package. Key electrical specifications include a collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a maximum power dissipation (PD) of 150 mW. The device features a typical base input resistance (R1) of 10 kOhms and an emitter-base resistance (R2) of 47 kOhms. It operates at a transition frequency (fT) of up to 250 MHz and supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates two NPN transistors with internal biasing resistors in a single ultra-small package
• Simplifies digital circuit design by eliminating external resistor components
• Supports high-frequency operation with a transition frequency of 250 MHz

Applications

• Differential amplifier circuits
• High-frequency crystal oscillators
• Starters and general-purpose digital switching applications

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm packaging configuration, as suffixes may indicate variations in tape-and-reel specifications or cut-tape availability. Confirm RoHS compliance status directly from the manufacturer's datasheet before finalizing procurement plans.

Selection Notes

Select the UMG5NTR when a dual NPN configuration with fixed 10 kOhm base and 47 kOhm emitter resistors is required. Ensure the 50 V voltage rating and 100 mA current capacity align with the target circuit requirements. Verify that the SOT-353 footprint matches the PCB layout constraints.

Part Context

This component belongs to the UMG series of complex transistors designed for space-constrained applications. It serves as a functional equivalent to discrete combinations such as the DTC114Y pair, offering a simplified alternative to using separate transistors and resistors in digital logic interfaces.
