UMB18N-TPQ2

Overview

The UMB18N-TPQ2 is a dual pre-biased transistor array manufactured by Micro Commercial Components (MCC). It integrates two NPN transistors with built-in biasing resistors within a compact SOT-363 surface-mount package. The device features a maximum collector-emitter voltage of 50V and a continuous collector current rating of 100mA. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at 10mA and 5V, a power dissipation capacity of 150mW, and a transition frequency of 200MHz. The unit operates reliably up to a maximum junction temperature of +150°C.

Feature Summary

• Integrates dual NPN transistors with pre-biased resistors for simplified circuit design
• Provides high-density packaging in a small SOT-363 form factor
• Supports high-speed switching applications with a 200MHz transition frequency
• Rated for high thermal stability with a maximum operating temperature of +150°C

Applications

• Signal switching and logic interface circuits
• Driver stages for low-power loads
• General-purpose amplification in consumer electronics
• Embedded system control interfaces

Procurement Notes

Verify the specific suffix 'Q2' against the manufacturer's latest documentation to confirm automotive qualification status or any revision differences compared to the standard UMB18N-TP variant. Ensure that the ordering information matches the exact package type and pin configuration required for the target PCB layout. Cross-reference the datasheet revision date to ensure compliance with current RoHS and REACH environmental standards before finalizing procurement.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required to reduce external component count and board space. The SOT-363 package is suitable for applications with strict size constraints. Consider the 50V voltage rating and 100mA current limit to ensure adequate headroom for the intended load. Verify that the thermal resistance and power dissipation capabilities align with the expected operating conditions and ambient temperatures of the final assembly.

Part Context

The UMB18N-TPQ2 belongs to MCC's line of pre-biased digital transistors, which combine bipolar junction transistors with internal resistor networks. This family is designed to replace multiple discrete components, simplifying schematic design and improving reliability. The Q2 suffix typically indicates specific automotive or enhanced quality grading within the broader UMB series portfolio, distinguishing it from standard commercial grade parts.

Replacement Considerations

Direct substitutes include the UMD18N-TP and UMD18N-TPQ2, which share identical electrical specifications and pinout configurations. The UMB9N-TP is a similar dual pre-biased array but utilizes PNP transistors instead of NPN, requiring polarity reversal in circuit design. Always verify pin compatibility and voltage ratings when substituting.
