DTA113ZM-TP

Overview

The DTA113ZM-TP is a pre-biased NPN digital transistor manufactured by Micro Commercial Components. It integrates an epitaxial planar silicon NPN transistor with bias resistors into a single SOT-523 surface-mount package. The device features built-in base resistor (R1) and base-emitter resistor (R2) to simplify circuit design and reduce component count. Key electrical characteristics include a maximum collector current of 100 mA, a power dissipation rating of 200 mW, and a DC current gain (hFE) minimum of 33 at specified conditions. The unit operates within a junction temperature range of -55°C to +150°C and complies with RoHS standards.

Feature Summary

• Integrates NPN transistor with dual internal bias resistors for simplified driving circuits
• Utilizes compact SOT-523 surface-mount packaging for space-constrained applications
• Constructed using epitaxial planar die technology for reliable performance
• Meets UL 94 V-0 flammability rating for epoxy material safety

Applications

• General-purpose switching applications in consumer electronics
• Driver circuits for logic level translation
• Interface modules requiring compact pre-biased transistor solutions

Procurement Notes

Verify the specific suffix ZM against the manufacturer's official datasheet to confirm pinout and electrical tolerances, as suffixes often denote specific resistance values or tape-and-reel configurations. Ensure the ordering documentation explicitly references Micro Commercial Components as the original equipment manufacturer to avoid counterfeit components. Cross-reference the Mouser part number 833-DTA113ZM-TP with the official MCC product listing for accurate availability status.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required for low-power switching tasks. The SOT-523 package is suitable for high-density PCB layouts where space is limited compared to larger packages like SOT-23. Verify that the 100 mA collector current and 200 mW power dissipation ratings meet the specific load requirements of the target application circuit before finalizing the design.

Part Context

This component belongs to the DTA/DTC series of pre-biased transistors from Micro Commercial Components. The DTA prefix typically indicates PNP polarity, while DTC indicates NPN; however, the specific model DTA113ZM-TP is documented as an NPN type in distributor listings. This series is designed to replace discrete resistor-transistor combinations, offering a standardized solution for digital logic interfacing and signal switching in modern electronic devices.

Replacement Considerations

Compatible substitutes include other NPN pre-biased transistors in the SOT-523 package with similar electrical ratings, such as the DTC113Z series from the same manufacturer. Verify that alternative parts match the internal resistor values and hFE specifications to ensure circuit compatibility without redesign.
