DTA144EM3T5G

Overview

The DTA144EM3T5G is a single NPN Digital Transistor (BRT) manufactured by onsemi, housed in an SOT-723-3 surface-mount package. It integrates a monolithic bias resistor network consisting of two resistors with a typical value of 47 kOhms each and a ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a minimum DC current gain (hfe) ranging from 80 to 140 and a power dissipation (Pd) of 260 mW. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates a single NPN transistor with a monolithic bias resistor network to replace discrete components.
• Designed to simplify circuit design by reducing board space and component count.
• Provides a compact surface-mount solution suitable for high-density applications.

Applications

• General-purpose switching circuits requiring simplified biasing networks.
• Interface logic level shifting where space constraints are critical.
• Consumer electronics assemblies utilizing standard digital transistor configurations.

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation to confirm exact electrical characteristics and mechanical dimensions before integration. Ensure compliance with RoHS directives and material declarations as specified in the official product data sheet. Cross-reference ordering suffixes to match packaging requirements such as cut tape or reel quantities.

Selection Notes

Select this component when a single NPN BRT with 47 kOhm base and base-emitter resistors is required. Compare against alternative resistor ratios if input impedance differs significantly from the 47 kOhm specification. Confirm that the 50 V voltage rating and 100 mA current capacity align with the target circuit's operational limits and thermal management capabilities.

Part Context

This part belongs to the DTC144 series of digital transistors from onsemi. It shares the same internal configuration as other variants in the family but is distinguished by its specific 47 kOhm resistor values and NPN polarity. The SOT-723 package offers a smaller footprint compared to traditional through-hole or larger surface-mount transistor packages.

Replacement Considerations

Direct substitutes include other NPN BRTs with identical 47 kOhm/47 kOhm resistor ratios and compatible pinouts, such as the DTC144 series from other manufacturers. Verify that replacement parts meet the same VCEO, Ic, and hfe specifications to ensure functional equivalence without redesigning the surrounding bias network.
