DTA113ZCA-HF

Overview

The DTA113ZCA-HF is a PNP digital transistor manufactured by Comchip Technology, designed for surface-mount applications. It integrates biasing resistors within an SOT-523-3 package to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. The device features a typical input resistor (R1) of 10 kOhms and a typical emitter-base resistor (R2) of 47 kOhms, resulting in a resistance ratio of approximately 4.7. Power dissipation is rated at 150 mW, with an operating temperature range spanning from -55°C to +150°C.

Feature Summary

• Integrates built-in biasing resistors to eliminate the need for external input components in inverter configurations.

Applications

• Automotive grade circuits requiring high reliability.
