DTC143ZUAT106

Overview

The DTC143ZUAT106 is a digital transistor with built-in bias resistor, manufactured by Rohm Semiconductor. It features an NPN transistor integrated with a single base resistor in a compact SMT package. The device offers high switching speed and low power consumption, making it suitable for various logic interface applications. Key electrical characteristics include a DC current gain (hFE) range of 100 to 200 at IC=5mA, and a collector-emitter saturation voltage (VCE(sat)) of 0.4V max at IC=10mA. The base resistor value is typically 10kΩ, providing stable biasing without external components.

Feature Summary

Integrated bias resistor eliminates need for external resistors
Compact surface-mount package design
High switching speed performance
Low power consumption operation

Applications

Logic level shifting circuits
Switching applications in portable devices
Interface circuits between microcontrollers and peripherals
Battery-powered equipment control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Check date codes and lot numbers against supply chain documentation. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Confirm package marking matches official specifications before integration into production lines.

Selection Notes

Consider thermal dissipation requirements when selecting this component for high-current applications. Evaluate base resistor tolerance impact on circuit stability. Assess operating temperature range compatibility with target environment. Verify pin configuration matches PCB layout design constraints.

Part Context

This component belongs to Rohm's digital transistor family designed for space-constrained applications. It replaces discrete transistor-resistor combinations, reducing board space and assembly complexity. The UAT106 suffix indicates specific packaging and tape-and-reel configuration for automated placement systems.

Replacement Considerations

Direct substitutes include DTC143ZT106 and DTC143ZTA106 from Rohm. Cross-brand alternatives require verification of hFE ranges and VCE(sat) specifications. Package dimensions must match existing footprint requirements.
