DTC113ZUA-TP

Overview

The DTC113ZUA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN epitaxial planar transistor with built-in biasing resistors in a compact SOT-323 surface-mount package. The device features a typical base resistor (R1) of 1 kOhms and an emitter-base resistor (R2) of 10 kOhms, resulting in a standard resistance ratio of 10. Key electrical specifications include a maximum collector current of 100 mA, a transition frequency of 250 MHz, and a power dissipation rating of 200 mW. The component supports a minimum DC current gain (hFE) of 33 at 5V/5mA and operates within a junction temperature range up to +150°C.

Feature Summary

• Integrates NPN transistor with pre-biased resistors for simplified circuit design
• Utilizes SOT-323 surface-mount packaging for space-constrained applications
• Features high-speed operation with a 250 MHz transition frequency
• Constructed using epitaxial planar die technology

Applications

• General-purpose switching circuits
• Driver applications for relays and solenoids
• Logic level translation interfaces
• High-frequency signal processing stages

Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required voltage ratings and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into assembly processes. Cross-reference ordering information with official distributor catalogs to validate current production status and availability constraints.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for high-speed switching. Ensure the 100 mA collector current limit and 200 mW power dissipation meet the load requirements. Verify that the SOT-323 footprint aligns with the PCB layout constraints and that the 1 kOhm input resistance matches the driving source impedance.

Part Context

This part belongs to the DTC113 series of digital transistors from Micro Commercial Components. It shares functional similarities with other SOT-323 packaged devices but is distinguished by its specific 1 kOhm/10 kOhm resistor network and NPN polarity. The series is designed to replace discrete resistor-transistor combinations, reducing board space and assembly complexity.

Replacement Considerations

Compatible substitutes include DTC113ZCA-TP (SOT-23-3L package) and DTC113ZE-TP (SOT-523 package), provided the pinout and electrical parameters are verified. Ensure any replacement maintains the same NPN configuration and resistor values to preserve circuit functionality.
