EMH11-TP

Overview

The EMH11-TP is a pre-biased bipolar transistor array manufactured by Micro Commercial Components. It contains two NPN transistors in a single SOT-563 surface-mount package. The device features a maximum collector-emitter voltage of 50V and a continuous collector current rating of 100mA. Power dissipation is limited to 150mW, with a transition frequency of 250MHz. Internal biasing resistors provide a ratio of 1.2, supporting a DC current gain of 30 at 5mA and 5V. Output saturation voltage is specified at 300mV under standard test conditions.

Feature Summary

• Integrates dual NPN pre-biased transistors within a compact SOT-563 surface-mount footprint
• Includes internal biasing network with a fixed resistor ratio for simplified circuit design
• Optimized for high-speed switching applications with a 250MHz transition frequency

Applications

• General-purpose signal switching circuits
• Logic level translation interfaces
• Driver stages for low-current loads

Procurement Notes

Verify the complete part number including the -TP suffix to ensure correct packaging and compliance specifications. Confirm that the SOT-563 footprint matches the target PCB layout dimensions. Cross-reference the manufacturer's latest datasheet for thermal derating curves and absolute maximum ratings prior to final design approval.

Selection Notes

Select this component when space constraints require dual NPN functions in a minimal outline. Ensure the application current remains below 100mA and voltage does not exceed 50V. Consider the 150mW power dissipation limit for thermal management. Verify that the internal biasing configuration aligns with the required drive characteristics.

Part Context

This device belongs to the family of pre-biased digital transistors offered by Micro Commercial Components. It serves as an alternative to discrete resistor-transistor networks, reducing component count and assembly time. The SOT-563 package provides a balance between pin count and board area efficiency for consumer electronics.

Replacement Considerations

Consult official substitution lists from Micro Commercial Components for verified equivalents. Ensure replacement parts maintain identical pinout configurations and electrical parameters such as Vceo and Ic ratings.
