EMD22-TP

Overview

The EMD22-TP is a dual pre-biased NPN transistor manufactured by Micro Commercial Components. It integrates two NPN transistors with built-in bias resistors in a single SOT-363 (SC-88) surface-mount package. The device features a collector-emitter voltage of 50V and a continuous collector current of 100mA. Each transistor section includes an internal base resistor, simplifying circuit design for switching applications. The component operates within a temperature range of -55°C to +150°C and dissipates up to 200mW of power.

Feature Summary

• Dual NPN configuration with integrated bias resistors
• Compact SOT-363 surface-mount packaging
• High thermal stability with extended operating temperature range

Applications

• General-purpose switching circuits
• Driver stages for low-power loads
• Logic interface buffering

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Micro Commercial Components or authorized distributors before procurement. Confirm that the SOT-363 footprint matches the target PCB layout requirements. Ensure supply chain authenticity through certified channels to avoid counterfeit components.

Selection Notes

Select this component when a compact dual NPN solution with fixed biasing is required. Compare the 100mA current rating and 50V voltage limit against circuit demands. Consider the internal resistor values if precise base drive currents are critical for the application timing.

Part Context

This part belongs to MCC's line of pre-biased digital transistors. It serves as a space-saving alternative to discrete NPN transistors paired with external base resistors. The EMD series typically offers matched characteristics between the two internal transistors for balanced performance in differential or push-pull configurations.

Replacement Considerations

Potential substitutes include the UMD22NHE3-TP from MCC or the EMD22T2R from ROHM. Verify pinout compatibility and electrical parameter equivalence, particularly the hFE gain and internal resistance values, before implementing any cross-brand replacement.
