Overview
The DTC123JKA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single NPN bipolar junction transistor with built-in biasing resistors, eliminating the need for external input components. The device features a collector-emitter maximum voltage of 50 V and a continuous collector current rating of 100 mA. Typical internal resistance values include a base resistor (R1) of 2.2 kOhms and an emitter resistor (R2) of 2.2 kOhms. The component operates within a temperature range of -55°C to +150°C and is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Integrates pre-biased resistors to simplify circuit design by removing the need for external input resistors.
- Provides a simple on/off switching mechanism suitable for inverter and interface applications.
- Utilizes a compact SOT-23-3 surface-mount package for efficient board space utilization.
Applications
- Inverter circuits
- Interface logic connections
- Driver stages
Procurement Notes
Verify the specific suffix against official MCC documentation to confirm pinout compatibility and electrical tolerances. Ensure the sourcing channel provides authentic components with traceable manufacturing data. Cross-reference the part number with authorized distributor lists to avoid counterfeit products. Confirm RoHS compliance status through the latest datasheet revision before final procurement decisions.
Selection Notes
Select this component when a compact NPN switching solution with integrated biasing is required. Compare the 50V breakdown voltage and 100mA current limits against load requirements. Evaluate the SOT-23-3 footprint constraints against available PCB real estate. Consider thermal dissipation capabilities relative to the expected duty cycle and ambient operating conditions.
Part Context
This part belongs to the broader family of digital transistors produced by Micro Commercial Components. These devices combine transistors and resistors into single packages to reduce assembly complexity. The DTC123JKA-TP specifically addresses applications requiring reliable NPN switching with minimal external component count.
Replacement Considerations
The DTC123JKA is a standard industry designation shared across multiple manufacturers such as ROHM and Rectron Semiconductor. Verify pinout alignment and electrical parameter equivalence before substituting with parts from other vendors like Jiangsu Changjiang or SeCoS.
