UMC5NTR

Overview

The UMC5NTR is a dual pre-biased transistor array manufactured by Rohm Semiconductor, housed in a surface-mount UMT5 package (SOT-353/SC-70-5). It integrates one NPN and one PNP digital transistor within a single component. The device supports a maximum collector-emitter voltage of 50V. Collector currents are rated at 30mA for the NPN section and 100mA for the PNP section. Internal base resistors are 47kΩ for the NPN and 4.7kΩ for the PNP, while emitter-base resistors are 47kΩ and 10kΩ respectively. The transition frequency is 250MHz, with a maximum power dissipation of 150mW.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors to simplify circuit design.
• Provides high-speed switching capabilities with a transition frequency of 250MHz.
• Utilizes a compact SOT-353 surface-mount package to minimize board space requirements.

Applications

• General-purpose digital switching circuits
• Interface drivers between logic families
• High-frequency signal processing applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging configuration. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production workflows. Cross-reference the part number with official distributor catalogs to validate availability and lead times.

Selection Notes

Select this component when a mixed NPN/PNP configuration is required in a minimal footprint. Ensure the internal resistor values align with the driving logic levels. Verify that the 150mW power dissipation limit accommodates the thermal conditions of the target application environment.

Part Context

This component belongs to the UMC5 series of complex transistors from Rohm Semiconductor. These devices are designed to replace multiple discrete components, reducing assembly complexity. The UMT5 package is standard for low-power surface-mount applications requiring dual transistor functionality.

Replacement Considerations

Publicly confirmed substitute part numbers include UMD5NTR and UMD12NTR. Verify pin compatibility and electrical specifications before substitution.
