DTC123JUA-TP

Overview

The DTC123JUA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with pre-biased resistors in a compact SOT-323 surface-mount package. The device features a typical base resistor of 2.2 kOhms and an emitter resistor of 47 kOhms, resulting in a typical resistance ratio of 21. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a power dissipation rating of 200 mW. The component supports a transition frequency of 250 MHz and maintains a minimum DC current gain (hFE) of 80 at 10 mA and 5 V. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrates NPN transistor with built-in biasing resistors for simplified circuit design
• Optimized for high-speed switching applications with a 250 MHz transition frequency
• Compact SOT-323 packaging suitable for space-constrained surface-mount layouts

Applications

• General-purpose switching circuits requiring integrated biasing
• High-frequency signal processing and RF interfaces
• Driver stages for logic level translation

Procurement Notes

Verify the specific suffix 'JUA' against official MCC documentation to confirm the internal resistor configuration, as variations exist within the DTC123 family. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference datasheet parameters such as hFE and saturation voltage with your design requirements before finalizing procurement decisions.

Selection Notes

Select this component when a pre-biased NPN solution is needed with a 2.2 kOhm base resistor. Compare the 200 mW power dissipation limit against thermal constraints in your application. Consider the SOT-323 footprint availability and ensure the 50 V voltage rating exceeds your circuit's peak operating conditions.

Part Context

This part belongs to the DTC123 series of digital transistors from Micro Commercial Components. It shares the same basic transistor structure with variants like DTC123EUA and DTC123YUA but differs in internal resistor values. The JUA suffix specifically denotes the 2.2 kOhm base and 47 kOhm emitter resistor combination.

Replacement Considerations

Direct substitutes may include other DTC123 variants with identical resistor ratios or equivalent NPN digital transistors from different manufacturers offering similar SOT-323 packages and electrical ratings. Verify pinout compatibility and thermal characteristics before substitution.
