UMB11N-TP

Overview

The UMB11N-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It features a dual NPN configuration housed in a SOT-363 surface-mount package. The device integrates internal biasing resistors to simplify circuit design and reduce component count. Key electrical specifications include a maximum collector-emitter voltage of 50V, a continuous collector current of 100mA, and a transition frequency of 250MHz. The unit offers a power dissipation rating of 150mW and operates within a temperature range from -55°C to +150°C. Typical input resistance is specified at 10kOhms with a resistor ratio of 1.

Feature Summary

• Dual NPN digital transistor architecture with integrated pre-biasing resistors
• Compact SOT-363 surface-mount packaging for space-constrained designs
• High-speed switching capability supported by 250MHz transition frequency
• Wide operating temperature range suitable for diverse environmental conditions

Applications

• General-purpose switching circuits requiring compact form factors
• Driver stages for low-power logic interfaces
• Signal conditioning and level shifting applications
• Battery-powered devices where component count reduction is critical

Procurement Notes

Verify the specific datasheet revision and compliance status before integration. Confirm availability through authorized distributors as supply levels may fluctuate. Ensure proper handling procedures are followed due to the small surface-mount package. Cross-reference pinouts with official documentation to prevent mounting errors during assembly processes.

Selection Notes

Select this component when a dual NPN configuration with fixed bias ratios is required. The 10kOhm input resistance suits standard logic interface applications. Consider the 150mW power dissipation limit for thermal management planning. Verify that the SOT-363 footprint aligns with existing PCB layout constraints and manufacturing capabilities.

Part Context

This part belongs to the UMB series of digital transistors from Micro Commercial Components. It shares the SOT-363 package format with other variants in the lineup but differs in internal resistor values and transistor configurations. The series is designed to replace multiple discrete components, offering a simplified solution for switching and amplification tasks in consumer and industrial electronics.

Replacement Considerations

Check for direct equivalents within the same manufacturer's portfolio that share identical pinouts and electrical characteristics. Verify compatibility with existing board layouts if substituting with similar packages from other vendors. Ensure that any alternative maintains the required 50V breakdown voltage and 100mA current ratings for safe operation.
