UMC2NT1G

Overview

The UMC2NT1G is a dual Bias Resistor Transistor (BRT) containing complementary NPN and PNP silicon transistors with monolithic bias resistor networks in an SC-88A/SOT-353 package. It integrates a series base resistor and a base-emitter resistor to replace discrete components. Maximum ratings include a collector-base voltage of 50 Vdc, collector-emitter voltage of 50 Vdc, and continuous collector current of 100 mAdc for both transistors. The device operates within a temperature range of -65°C to +150°C with a total package dissipation of 150 mW at 25°C ambient.

Feature Summary

• Integrates complementary NPN and PNP transistors with monolithic bias resistor networks into a single surface mount device
• Reduces board space and component count by eliminating external resistor bias networks
• Available in lead-free, halogen-free, and RoHS compliant packages

Applications

• Low power surface mount applications where board space is limited
• Automotive and other applications requiring unique site and control change requirements
• Digital switching circuits requiring simplified design

Procurement Notes

Verify the specific ordering suffix and prefix when sourcing. The NSV prefix indicates AEC-Q101 qualification and PPAP capability for automotive use. Confirm the package type is SC-88A/SOT-353 and check for Pb-Free compliance. Ensure the procurement matches the exact part number as variations exist within the UMC2NT1 family.

Selection Notes

Select the UMC2NT1G when a complementary pair of digital transistors is required in a minimal footprint. Verify that the integrated resistor values meet the circuit biasing requirements. Consider the thermal resistance of 833 °C/W for heat dissipation calculations. Ensure the operating voltage does not exceed the 50 Vdc limits for either transistor type.

Part Context

The UMC2NT1G belongs to the UMC2NT1 series of dual common base-collector bias resistor transistors. This series includes complementary devices housed in the SOT-353 package. Other variants in the family include UMC3NT1G and UMC5NT1G, which differ primarily in their internal resistor values.

Replacement Considerations

Direct substitutes within the same family include NSVUMC2NT1G, which shares identical electrical characteristics but carries the NSV prefix for automotive qualification. Other members like UMC3NT1G or UMC5NT1G may serve as functional replacements if their specific resistor ratios align with the application needs.
