UMF7NTR

Overview

The UMF7NTR is a dual digital transistor manufactured by ROHM Semiconductor, featuring an NPN/PNP configuration within a compact SOT-363 (UMT6) surface-mount package. It integrates bias resistors to simplify circuit design, offering a collector-emitter voltage of 50V and continuous collector current of 100mA for both elements. The device operates with a maximum power dissipation of 150mW and supports junction temperatures up to +150°C. Designed for high-frequency applications, it achieves a maximum operating frequency of 250MHz. Typical input resistance values are specified at 4.7kΩ for the NPN section and 47kΩ for the PNP section, ensuring efficient signal processing in low-power digital logic interfaces.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific ordering suffixes against official datasheets. Ensure storage conditions adhere to moisture sensitivity levels to prevent package degradation prior to assembly.

Selection Notes

Select this component when a combined NPN/PNP solution is required to reduce board space. Verify that the 50V rating and 100mA current capacity meet circuit demands. Check input resistance requirements against the typical 4.7kΩ/47kΩ values to ensure proper biasing without external components.

Part Context

Part of the UMF series from ROHM Semiconductor, designed for general-purpose digital switching. The UMT6 package variant offers a small footprint compared to discrete transistor arrangements. This series supports miniaturization trends in modern electronic devices requiring reliable bipolar switching performance.

Replacement Considerations

Consult official substitution guides for equivalent dual digital transistors. Verify pinout compatibility and electrical parameters such as Vceo and hFE before replacing. Consider packages like SOT-363 equivalents from other manufacturers if supply constraints exist.
