Overview
The DTC143ZCAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It features built-in biasing resistors within an SOT-23 surface-mount package. The device supports a maximum supply voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 200 mW. Internal resistor values include a typical base resistance (R1) of 4.7 kOhms and an emitter resistance (R2) of 47 kOhms, yielding a ratio of 10. The component meets AEC-Q101 automotive qualification standards and operates across a junction temperature range from -55 °C to +150 °C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Built-in biasing resistors simplify circuit design
- AEC-Q101 qualified for automotive applications
- Halogen-free green device compliant with RoHS
Applications
- Automotive electronic systems requiring pre-biased switching
- General-purpose digital switching circuits
- Interface driver applications in consumer electronics
Procurement Notes
Verify the authenticity of the DTC143ZCAHE3-TP through authorized MCC distributors or direct channels. Ensure the ordering suffix 'TP' corresponds to the RoHS-compliant lead-free finish as specified in the official datasheet. Confirm that the SOT-23 package dimensions align with your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a compact NPN switch with integrated biasing is required. The 4.7 kOhm base resistor suits standard logic interface levels. Verify that the 100 mA collector current and 200 mW power dissipation meet the thermal and load demands of the specific application environment.
Part Context
This part belongs to the DTC143 series of digital transistors from Micro Commercial Components. It shares the same internal configuration as other variants but utilizes the SOT-23 package. The HE3 designation indicates Halogen-free compliance, while the TP suffix denotes RoHS compatibility.
Replacement Considerations
Compatible substitutes include the DTC143ZCA-TP and DTC143TCA-TP. Verify that the replacement maintains the SOT-23 package and identical electrical characteristics, specifically the 4.7 kOhm base resistor value and 50 V breakdown voltage.
