UMD9N-TPQ2

Overview

The UMD9N-TPQ2 is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two NPN transistors with built-in bias resistors into a single surface-mount package. The device features a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. Typical input resistance is 10kΩ, with a DC current gain minimum of 68 at 5mA and 5V. Power dissipation is rated at 150mW, operating within a temperature range of -55°C to +150°C. The component utilizes an SOT-363 package for compact circuit integration.

Feature Summary

• Dual NPN configuration with integrated base bias resistors
• High switching speed suitable for digital logic applications
• Compact SOT-363 surface-mount packaging

Applications

• Digital logic level shifting
• Switching circuits in consumer electronics
• Driver stages for small-signal loads

Procurement Notes

Verify the exact suffix 'Q2' against official MCC documentation to confirm automotive qualification status or specific tape-and-reel specifications. Standard distributors may list only the base 'UMD9N-TP' part number; ensure the datasheet matches the requested variant before ordering.

Selection Notes

Select this component when a dual NPN digital transistor with 50V rating and 100mA current capacity is required. The SOT-363 package is ideal for space-constrained designs. Ensure the 10kΩ input resistance aligns with the driving source impedance requirements of the target application circuit.

Part Context

This part belongs to the UMD9N series of pre-biased digital transistors from Micro Commercial Components. These devices are designed to replace multiple discrete components, reducing board space and assembly costs. The series typically includes variants with different resistor values and transistor polarities.

Replacement Considerations

Check for direct substitutes such as UMD9N-TP from other manufacturers offering identical pinouts and electrical characteristics. Verify that any replacement maintains the same SOT-363 footprint and thermal performance.
