UMA7NTR

Overview

The UMA7NTR is a dual PNP digital transistor from ROHM Semiconductor, housed in a SOT-353-5 package. It features a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device includes built-in resistors for convenient digital circuit integration. Key electrical specifications include a minimum DC current gain (hfe) of 68 at specified conditions, a power dissipation of 150 mW, and an operating temperature range up to +150 C. The component is designed for surface mount applications.

Feature Summary

• Integrated dual PNP transistors with pre-biased resistors
• High collector current capability of 100 mA
• Compact SOT-353-5 surface mount packaging
• Extended maximum operating temperature of +150 C

Applications

• Digital logic interface circuits
• Signal switching applications
• General-purpose amplifier stages

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before procurement, as manufacturing data may vary. Confirm that the UMT5 or SOT-353-5 package designation matches your PCB footprint requirements exactly. Ensure that the NRND status does not impact long-term supply chain stability for your production timeline.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing resistors is required. The 50 V breakdown voltage and 100 mA current rating suit low-voltage digital switching tasks. Consider the thermal performance within the 150 mW dissipation limit and the +150 C temperature ceiling during design validation.

Part Context

The UMA7NTR belongs to the UMA7N series of digital transistors manufactured by ROHM Semiconductor. These devices combine two PNP transistors with internal resistors to simplify circuit design. The series is characterized by compact packaging and high reliability, targeting modern electronics requiring space-efficient solutions.
