UMH13N-TP-HF

Overview

The UMH13N-TP-HF is a dual NPN pre-biased digital transistor manufactured by Micro Commercial Components (MCC). It integrates two NPN transistors with internal base resistors into a single surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a continuous collector current rating of 100mA. Internal specifications include a base resistor value of 4.7 kOhms, a DC current gain minimum of 80 at 10mA and 5V, and a saturation voltage maximum of 300mV under specified conditions. The component operates within a junction temperature range of -55°C to +150°C and has a maximum power dissipation of 150mW.

Feature Summary

• Integrates dual NPN transistors with built-in base biasing resistors for simplified circuit design
• Provides high switching speed capabilities suitable for digital logic applications
• Offers compact surface-mount packaging to minimize board space requirements

Applications

• General-purpose digital switching circuits
• Interface drivers between logic families
• Level shifting applications in low-power systems

Procurement Notes

Verify the specific suffix configuration when sourcing, as variations may exist regarding halogen content or packaging standards. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the ordering part number matches the required electrical characteristics and package type exactly to avoid substitution errors during assembly.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required to reduce external component count. Evaluate the 4.7 kOhm base resistance against the driving source capability to ensure adequate base current. Consider the 150mW power dissipation limit relative to the expected thermal environment and duty cycle of the application.

Part Context

This part belongs to the UMH13 series of pre-biased transistors from MCC. It shares the SOT-363 package form factor with other devices in the family but differs in internal resistor values and transistor parameters. The -HF suffix typically indicates halogen-free manufacturing compliance, distinguishing it from standard versions in procurement channels.

Replacement Considerations

Direct substitutes must match the SOT-363 package, dual NPN configuration, 50V Vceo, and 4.7 kOhm base resistance. Verify pinout compatibility and thermal characteristics before replacing. Cross-reference with other manufacturers' dual NPN pre-biased transistors offering identical electrical ratings.
