DRA2144V0L

Overview

The DRA2144V0L is a single PNP digital transistor manufactured by Panasonic Industry. It integrates a built-in bias resistor with a typical resistance of 47 kOhms, designed for simplified circuit configurations. The component operates within a collector-emitter voltage (VCEO) range of -50 V and supports a continuous collector current of -100 mA. It is housed in the Mini3-G3-B surface-mount package, measuring approximately 2.9x2.8mm. The device is rated for a maximum operating temperature of +150 C and complies with RoHS standards.

Feature Summary

• Integrates a built-in bias resistor to reduce external component count and simplify circuit design.
• Utilizes a compact Mini3-G3-B surface-mount package for efficient board space utilization.
• Supports high-temperature operation up to +150 C for robust performance in demanding environments.

Applications

• General-purpose switching applications requiring integrated biasing.
• Interface circuits between logic gates and load devices.
• Driver stages for low-current electronic loads.

Procurement Notes

Verify availability status carefully as the component is listed as End-of-Life (EOL). Confirm specific ordering suffixes against official Panasonic documentation to ensure correct package and tape/reel specifications. Request updated Product Change Notifications (PCN) or discontinuation notices from authorized distributors to assess long-term supply viability for production planning.

Selection Notes

Select this component when a PNP digital transistor with a 47 kOhm internal bias resistor is required. Ensure the application voltage does not exceed the -50 V collector-emitter rating and current demands remain within the -100 mA limit. Verify that the Mini3-G3-B footprint matches the PCB layout constraints and that the thermal environment supports the specified maximum operating temperature.

Part Context

The DRA2144V0L belongs to the Panasonic DRA series of resistor-biased transistors. This series consolidates discrete bipolar junction transistors and bias resistors into single packages. The specific model utilizes a PNP configuration with an integrated 47 kOhm resistor, offering a compact alternative to discrete component arrangements in signal processing and switching circuits.

Replacement Considerations

Consult official Panasonic substitution guides for verified equivalents. Potential alternatives include other PNP digital transistors with similar 47 kOhm bias ratios and compatible voltage/current ratings, provided the physical footprint and electrical characteristics align with the original design requirements.
