UMH9NHE3-TP

Overview

The UMH9NHE3-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 (Vceo) of 50V and a continuous collector current (Ic) of 100mA. The device features a typical base resistor (R1) value of 10 kΩ, a minimum DC current gain (hFE) of 68 at 5mA/5V, and a transition frequency (fT) of 250MHz. It operates within a temperature range of -55°C to +150°C with a power dissipation of 150mW.

Feature Summary

• Dual NPN configuration with integrated biasing resistors for simplified circuit design
• AEC-Q101 qualified for automotive reliability standards
• Compact SOT-363 package suitable for space-constrained applications

Applications

• Automotive electronic control units requiring AEC-Q101 compliance
• High-speed switching circuits operating up to 250MHz
• Digital logic interface and level shifting applications

Procurement Notes

Verify the specific suffix HE3 indicates Halogen-free and RoHS compliance status against the manufacturer's latest documentation. Confirm that the AEC-Q101 qualification applies to the specific batch or lot codes intended for automotive use. Ensure the ordering quantity matches the standard reel size of 3,000 units if tape-and-reel packaging is required for automated assembly processes.

Selection Notes

Select this component when a dual NPN digital transistor with a 10kΩ base resistor is required. The 50V rating and 100mA current capacity suit low-power switching tasks. Compare hFE minimums and saturation voltages against alternative series like UMD12NHE3-TP if higher gain or different resistance ratios are needed. Verify thermal management requirements given the 150mW power dissipation limit in the small SOT-363 footprint.

Part Context

This part belongs to the UMH9N series of pre-biased transistors from Micro Commercial Components. It shares the same physical package and general electrical characteristics as the non-qualified UMH9N-TP variant but includes additional automotive-grade testing and certification. The HE3 suffix typically denotes environmental compliance features such as halogen-free materials, distinguishing it from standard commercial grade parts in the same family.

Replacement Considerations

The UMH9N-TP is a direct functional substitute lacking automotive qualification. For single-transistor replacements, consider DTC143T variants. Cross-manufacturer equivalents should be verified for pin compatibility and electrical limits.
