Overview
The DTC143ZCA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates a single epitaxial silicon NPN transistor with built-in bias resistors in a surface-mount SOT-23 package. Key electrical parameters include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a maximum power dissipation of 200 mW. The device features a base resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 47 kOhms. It offers a minimum DC current gain (hFE) of 80 at 10 mA and 5 V, with a transition frequency of 250 MHz.
Feature Summary
- Integrates a single NPN transistor with built-in bias resistors to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable performance.
- Encapsulated in a compact SOT-23 surface-mount package.
Applications
- Switching applications requiring pre-biased control.
- Driver circuits for logic interfaces.
- General-purpose amplification stages.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout configuration and resistance values. Ensure compliance with RoHS3 standards and check moisture sensitivity level requirements during storage and handling procedures before assembly.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required. Compare the 4.7 kOhm/47 kOhm resistor ratio against other DTC143 variants if different input impedance characteristics are needed. Confirm that the 50 V breakdown voltage meets the system's operational limits.
Part Context
This part belongs to the DTC143 series of digital transistors from MCC. It is functionally similar to other industry-standard NPN digital transistors but is distinguished by its specific internal resistor network and packaging. The 'TP' suffix typically indicates tape and reel packaging availability.
Replacement Considerations
Compatible substitutes include the DTC143ZUA-TP and DTC143ZCAHE3-TP from the same manufacturer. Verify that alternative parts maintain the same SOT-23 footprint and electrical ratings before substitution.
