EMD3-TP

Overview

The EMD3-TP is a dual digital transistor from Micro Commercial Components, integrating one NPN and one PNP transistor within an SOT-563 (EMT6) surface-mount package. This configuration provides two complete biasing circuits in a single compact component. The device features internal base-emitter resistors for simplified interface design and stable operation. It supports a maximum collector-emitter voltage of 50V and continuous collector currents up to 100mA per transistor. With a power dissipation rating of 200mW and an operating temperature range extending to +150°C, it serves as a robust solution for switching and logic interfacing applications.

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in biasing resistors into a single ultra-small package
• Provides simplified circuit design by eliminating external resistor requirements for base drive networks
• Supports high-temperature operation suitable for demanding electronic environments

Applications

• Differential amplifier input stages requiring matched or complementary transistor pairs
• High-frequency crystal oscillator circuits utilizing integrated biasing
• General-purpose logic level shifting and switching interfaces

Procurement Notes

Verify the specific suffix against official MCC documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing PCB footprints for the SOT-563 form factor. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement plans.

Selection Notes

Select this component when space constraints necessitate combining both NPN and PNP functions into one footprint. Compare internal resistance values against application requirements to ensure proper biasing without external components. Evaluate thermal management needs given the 200mW power dissipation limit in the small outline package.

Part Context

This part belongs to the family of complex transistors designed to replace multiple discrete components. Similar products include the DTA114E series for single-transistor applications. The EMD3-TP specifically addresses designs requiring simultaneous NPN and PNP switching capabilities in minimal board area.

Replacement Considerations

Direct substitutes may include other dual digital transistors in SOT-563 packages such as the EMD3 equivalents from other manufacturers. Verify pinout compatibility and electrical parameter alignment before substitution.
