EMD2-TP

Overview

The EMD2-TP is a dual digital transistor from Micro Commercial Components, integrating one NPN and one PNP epitaxial planar silicon transistor with built-in bias resistors into a single SOT-563 (EMT6) surface-mount package. This configuration provides a collector-emitter voltage of 50V for the NPN element and -50V for the PNP element. The device supports a continuous collector current of 100mA and features a typical input resistance of 1kΩ or 22kΩ with a resistance ratio of 1:1 or 22:1. It operates within a junction temperature range of -55°C to +150°C and dissipates up to 150mW of power.

Feature Summary

• Integrates independent NPN and PNP transistor elements with built-in resistors in a compact SOT-563 package to reduce board space and mounting costs.

Applications

• Differential amplifier circuits
• High-frequency crystal oscillator drivers
• General-purpose switching applications requiring complementary logic levels

Procurement Notes

Verify the specific resistor values and polarity configuration required for the design, as the UMD2N series offers variations in input resistance. Confirm that the SOT-563 footprint matches the PCB layout constraints. Ensure the supplier provides the official datasheet to validate electrical characteristics against the application requirements.

Selection Notes

Select this component when a complementary pair of digital transistors is needed in a minimal footprint. Compare the internal resistor ratios against standard single-transistor digital equivalents like DTA124E or DTC124E if discrete solutions are considered. Verify thermal dissipation limits relative to the ambient operating conditions.

Part Context

This part belongs to the UMD2N series of dual digital transistors manufactured by MCC. It serves as a direct equivalent to ROHM's EMD2 device, offering identical pinout and functional characteristics. The series is designed for applications where space savings and simplified circuit design are prioritized over discrete component assembly.

Replacement Considerations

The ROHM EMD2 is a confirmed public substitute. Other compatible parts include the UMD2NS-TP from MCC, which shares the same dual NPN/PNP configuration and SOT-363/EMT6 packaging.
