DTA143EU3HZGT106

Overview

The DTA143EU3HZGT106 is a PNP digital transistor manufactured by ROHM Semiconductor, designed for surface-mount applications in the SOT-323 (UMT3) package. It integrates bias resistors with typical values of R1 = 4.7 kΩ and R2 = 4.7 kΩ, enabling simplified circuit design without external input components. The device supports a supply voltage of -50 V and a continuous collector current of -100 mA, with a maximum power dissipation of 200 mW. It features a minimum DC current gain (hFE) of 30 at -10 mA and -5 V, and operates up to a maximum frequency of 250 MHz. Qualified under AEC-Q101 standards, it ensures high reliability for automotive environments.

Feature Summary

• Integrates built-in biasing resistors (R1=R2=4.7kΩ) to simplify inverter circuit configuration without external input resistors.
• AEC-Q101 qualified for high reliability in automotive-grade electronic systems.
• Compact SOT-323 (UMT3) surface-mount package suitable for space-constrained designs.

Applications
