EMH1-TP

Overview

The EMH1-TP is a dual NPN digital transistor manufactured by Micro Commercial Components. It integrates two NPN transistors with built-in base resistors into a single SOT-563 surface-mount package. This configuration simplifies circuit design by reducing component count and board space requirements. The device features a transition frequency of 250MHz and a minimum DC current gain of 80 at a collector current of 10mA and Vce of 5V. The maximum collector cutoff current is specified at 100mA, ensuring reliable switching performance for digital logic applications.

Feature Summary

• Integrates dual NPN transistors with internal base resistors in a compact SOT-563 package
• Optimized for high-speed switching with a 250MHz transition frequency
• Provides simplified circuit design through integrated resistor network functionality

Applications

• Digital logic interface circuits
• Switching applications in consumer electronics
• Signal level translation between logic families

Procurement Notes

Verify the exact part number suffix to ensure compatibility with specific packaging or tape-and-reel configurations. Confirm that the supplier is an authorized distributor of Micro Commercial Components to guarantee authenticity. Cross-reference the datasheet specifications against your circuit requirements, particularly the current gain and cutoff current limits. Ensure the SOT-563 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when space-saving dual transistor solutions are required for NPN switching tasks. The integrated resistors eliminate the need for external base drive components, reducing assembly complexity. Consider the 250MHz transition frequency for high-speed digital applications where standard bipolar transistors may be too slow. Verify that the SOT-563 package size fits within the available board area compared to discrete transistor alternatives.

Part Context

The EMH1-TP belongs to the family of digital transistors offered by Micro Commercial Components. These devices combine transistors and resistors to simplify biasing networks. The SOT-563 package is a common small-outline surface-mount technology format used in portable and compact electronic devices. This integration approach is standard for reducing bill-of-materials costs in mass-produced consumer electronics.
