DRA5144W0L

Overview

The DRA5144W0L is a single PNP pre-biased bipolar transistor manufactured by Panasonic Electronic Components. It features an integrated base resistor with a typical value of 10 kOhms, designed for digital circuit applications. The device operates within a collector-emitter voltage range of -50 V and supports a continuous collector current of -80 mA. Packaged in the SMini3-F2-B surface-mount format, it offers a maximum operating temperature of +150°C and a power dissipation rating of 150 mW. This component is engineered to provide high forward current transfer ratio with excellent linearity.

Feature Summary

• Integrates a built-in base resistor to simplify circuit design and reduce component count.
• Delivers high forward current transfer ratio (hFE) with excellent linearity characteristics.
• Achieves low collector-emitter saturation voltage to enhance efficiency.
• Utilizes an eco-friendly halogen-free package compliant with environmental directives.

Applications

• Digital switching circuits requiring compact footprint solutions.
• Signal conditioning interfaces in networking applications.
• General-purpose amplification stages in consumer electronics.

Procurement Notes

Verify availability status carefully as supply conditions may vary. Confirm RoHS compliance and halogen-free certification through official datasheets before integration. Ensure compatibility with existing PCB footprints and thermal management requirements. Check for any specific handling instructions related to the SMini3-F2-B package during assembly processes.

Selection Notes

Select this component when space constraints necessitate a small surface-mount package like SMini3-F2-B. Consider its PNP polarity and -50 V rating for appropriate voltage levels. The integrated 10 kOhm resistor simplifies biasing networks. Evaluate the 150 mW power dissipation limit against thermal loads in the target application environment.
