DTC143XE-TP

Overview

The DTC143XE-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC). It is a pre-biased single BJT housed in the SOT-523 surface-mount package. The device features a maximum collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA. Electrical specifications include a DC current gain (hFE) minimum of 20 at 10 mA and 5 V, with a maximum saturation voltage of 300 mV under specific bias conditions. The component supports a transition frequency of 250 MHz and has a maximum power dissipation of 150 mW.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Provides high-speed switching capabilities suitable for digital logic applications.
• Utilizes a compact SOT-523 footprint for efficient space-constrained PCB layouts.

Applications

• General-purpose digital switching circuits
• Logic level translation interfaces
• Driver stages for small-signal loads

Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status and packaging format requirements with the supplier prior to purchase. Ensure availability aligns with project timelines as supply constraints may affect delivery schedules.

Selection Notes

Select this component when a compact NPN digital transistor with integrated biasing is required. Verify that the 50 V voltage rating and 100 mA current capacity meet the load requirements. Compare the SOT-523 package dimensions against the target PCB footprint to ensure mechanical compatibility.

Part Context

This part belongs to the DTC143 series of pre-biased transistors from MCC. The series offers various packages including SOT-23 and SOT-523. The XE suffix typically denotes the specific SOT-523 configuration within this product line, distinguishing it from other package variants like the TCA or TE models.

Replacement Considerations

Check for direct substitutes such as the DTC143TE-TP or DTC143EE-TP if package variations are acceptable. Verify pinout compatibility before substituting with components from other manufacturers to ensure functional equivalence.
