UMH9N-TP

Overview

The UMH9N-TP is a dual NPN pre-biased transistor array manufactured by Micro Commercial Components. It integrates two NPN transistors with internal base resistors in a compact SOT-363 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The device features a typical base resistor value of 10 kOhms, a minimum DC current gain (hFE) of 68 at 5mA/5V, and a transition frequency of 250MHz. Maximum power dissipation is rated at 150mW.

Feature Summary

• Integrates dual NPN transistors with built-in biasing resistors to reduce external component count.
• Designed for high-speed switching applications with a 250MHz transition frequency.
• Utilizes a compact SOT-363 package suitable for space-constrained printed circuit board layouts.

Applications

• General-purpose digital switching circuits
• Interface drivers for logic level translation
• High-frequency signal processing stages

Procurement Notes

Verify the specific manufacturer suffix against official datasheets to confirm exact electrical tolerances and packaging variations. Ensure compatibility with automated pick-and-place equipment due to the small SOT-363 form factor. Cross-reference pinout configurations with target PCB footprints to prevent installation errors during assembly processes.

Selection Notes

Select this component when dual NPN switching functionality with integrated biasing is required in a minimal footprint. Compare the 10kOhm base resistor value against circuit requirements to ensure proper drive current levels. Evaluate the 50V voltage rating against peak operating conditions to maintain adequate safety margins for reliable long-term performance.

Part Context

This part belongs to the UMH9N series of digital transistors from Micro Commercial Components. It serves as a discrete alternative to complex driver ICs, offering simplified design integration for low-power switching tasks. The series provides standardized electrical characteristics across multiple resistor ratio options within the same package family.

Replacement Considerations

The ROHM Semiconductor UMH9NTN is a publicly confirmed substitute part number with identical dual NPN configuration and SOT-363 packaging. Verify pin-to-pin compatibility and minor parameter deviations before finalizing any substitution decisions.
