DTC144EM-TP

Overview

The DTC144EM-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in the SOT-723 surface-mount package. It integrates biasing resistors R1 and R2, with nominal values of 47 kΩ each. Key electrical specifications include a maximum supply voltage (VCC) of 50 V, a collector current (IC) limit of 100 mA, and a power dissipation (PD) rating of 100 mW at 25°C. The device features a transition frequency (fT) of 250 MHz and a DC current gain (GI) of 68. Input resistance ranges from 32.9 to 61.1 kΩ, while output leakage current remains below 0.5 μA.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Built-in biasing resistors simplify circuit design
• Halogen-free "Green" device compliant with environmental standards
• Moisture sensitivity level 1 classification

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify authenticity by purchasing only from authorized MCC distributors or directly from the manufacturer. Unauthorized sources lack traceability and quality assurance. Confirm the part marking "26" matches the datasheet. Ensure the ordering suffix "-TP" indicates tape-and-reel packaging containing 8,000 pieces per reel. Check RoHS compliance status before integration.

Selection Notes

Select this component when a compact NPN digital switch with integrated biasing is required. The SOT-723 package suits space-constrained designs. Verify that the 100 mA collector current and 50 V breakdown voltage meet system requirements. Consider the 100 mW power dissipation limit and derating curves for thermal management in high-ambient temperature environments.

Part Context

The DTC144EM-TP belongs to the DTC144EM series of NPN digital transistors. It is designed as a replacement for discrete resistor-transistor networks, reducing board space and assembly complexity. The device is suitable for general-purpose switching and logic interface applications where small form factors are critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other manufacturers' NPN digital transistors in the SOT-723 package only after verifying pinout compatibility and electrical parameter equivalence.
