UMD9N-TP

Overview

The UMD9N-TP is a digital transistor manufactured by Micro Commercial Components (MCC). It features an NPN dual configuration housed in a compact surface-mount package. The device integrates internal biasing resistors to simplify circuit design and reduce component count. Key electrical characteristics include a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The unit supports a power dissipation of 150mW and operates within a temperature range of -55°C to +150°C. It is supplied in reel or cut tape formats, with a standard factory packaging quantity of 3000 units per reel.

Feature Summary

• Dual NPN digital transistor architecture for space-efficient designs
• Integrated base and emitter biasing resistors
• High switching frequency capability up to 250 MHz
• Low saturation voltage for efficient power handling

Applications

• General-purpose switching circuits
• Driver stages for relays and solenoids
• Logic level translation interfaces
• Buffer amplifiers in consumer electronics

Procurement Notes

Verify the specific datasheet revision before ordering, as manufacturing notifications may update specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as regulatory details are subject to change. Ensure the required packaging format (Reel or Cut Tape) matches your assembly line equipment capabilities. Cross-reference the Mouser part number 833-UMD9N-TP for accurate sourcing channels.

Selection Notes

Select this component when a dual NPN digital transistor is required in a small SMD footprint. The integrated resistor network eliminates the need for external biasing components, reducing board space and assembly time. Verify that the 50V Vceo and 100mA Ic ratings exceed your circuit's maximum operating conditions. Consider the 150mW power dissipation limit relative to your thermal management strategy.

Part Context

This part belongs to the UMD9N series of digital transistors from Micro Commercial Components. It is functionally similar to other dual NPN pre-biased transistors but offers specific internal resistance values defined by the manufacturer. The TP suffix typically indicates a specific packaging or environmental compliance variant within the MCC product line.

Replacement Considerations

Direct pin-compatible substitutes include the UMH9NHE3-TP from the same manufacturer family. Other generic equivalents may exist, but verification of internal resistor ratios and hFE parameters is essential to ensure circuit compatibility without modification.
