EMD22-13P

Overview

The EMD22-13P is a digital transistor manufactured by Micro Commercial Components (MCC). It is configured as a dual single NPN type, integrating two NPN transistors within a single package. The component features a typical input resistance of 22 kOhms with a corresponding resistor ratio of 21. It is designed for surface mount device (SMD/SMT) installation and utilizes the SOT-23-3L package configuration. Key electrical specifications include a minimum DC collector/base gain (hfe) of 100, a maximum operating frequency of 250 MHz, and a maximum collector-emitter voltage (VCEO) of 50 V. The device supports a continuous collector current of 100 mA and a peak DC collector current of 100 mA, with a power dissipation rating of 150 mW. It operates within a temperature range from -55°C to +150°C.

Feature Summary

• Integrates dual single NPN transistors in a compact SOT-23-3L package for space-efficient circuit design.
• Includes built-in 22 kOhm input resistors to simplify biasing networks and reduce external component count.
• Supports high-frequency operation up to 250 MHz for use in RF and switching applications.

Applications

• Switching circuits requiring integrated biasing resistors
• Driver stages for low-power logic interfaces
• High-frequency signal processing applications

Procurement Notes

Verify the specific manufacturer datasheet for the EMD22-13P to confirm pinout compatibility and absolute maximum ratings before integration. Ensure that the selected supplier provides traceable documentation matching the MCC part number. Cross-reference the SOT-23-3L package dimensions with your PCB footprint library to guarantee mechanical fit. Confirm thermal management requirements align with the 150 mW power dissipation limit under expected operating conditions.

Selection Notes

Select this component when a dual NPN configuration with integrated base resistors is required to minimize board space. The 22 kOhm input resistance suits standard logic levels, while the 50 V VCEO rating provides adequate headroom for low-voltage systems. Consider the 250 MHz frequency limit for high-speed switching needs. Verify that the SOT-23-3L package is compatible with your assembly process and that the -55°C to +150°C temperature range meets environmental specifications.

Part Context

This part belongs to the broader category of digital transistors offered by Micro Commercial Components. These devices combine bipolar junction transistors with internal resistors to replace multiple discrete components. The EMD22-13P specifically addresses designs needing dual NPN switching capabilities in a minimal footprint. Such components are commonly used in consumer electronics and industrial control panels where space conservation and simplified bill of materials are critical design drivers.

Replacement Considerations

Publicly confirmed substitute part numbers for the EMD22-13P are not available in the provided reference data. Verify functional equivalents by matching the dual NPN configuration, 22 kOhm input resistance, SOT-23-3L package, and 50 V VCEO rating from other manufacturers.
