UMF5NTR

Overview

The UMF5NTR is a pre-biased dual transistor array manufactured by Rohm Semiconductor, housed in a UMT6 surface-mount package. It integrates one NPN and one PNP digital transistor within a single compact footprint. The NPN section supports a maximum collector current of 100mA with a 50V collector-emitter breakdown voltage, while the PNP section handles up to 500mA at 12V. Both transistors feature integrated base resistors of 47kΩ and emitter-base resistors of 47kΩ. The device offers a transition frequency of 250MHz for the NPN and 260MHz for the PNP, with a total power dissipation rating of 150mW.

Feature Summary

• Integrates complementary NPN and PNP pre-biased transistors into a single six-terminal surface-mount package.
• Includes built-in biasing resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities with transition frequencies exceeding 250MHz.

Applications

• General-purpose digital switching circuits requiring complementary logic levels.
• Interface drivers for microcontrollers needing both sourcing and sinking capabilities.
• Low-power signal processing stages in portable electronic devices.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to ensure correct packaging configuration. Confirm that the UMT6 package dimensions align with your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure availability matches your production timeline as lead times may vary.

Selection Notes

Select this component when a mixed NPN/PNP configuration is needed in a minimal space. Compare the 100mA/500mA current ratings against your load requirements. Verify that the 47kΩ internal resistors provide appropriate base drive for your application voltage. Consider the 150mW power dissipation limit under your expected operating conditions.
