DRA5144T0L

Overview

The DRA5144T0L is a PNP digital transistor manufactured by Panasonic Electronic Components. It integrates a single bipolar junction transistor with a built-in bias resistor, housed in an SSMini3 F3 B surface-mount package measuring 1.6 x 0.85 x 0.6 mm. The device features a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. It includes a typical input resistance of 10 kΩ and offers a minimum DC current gain (hFE) of 160. The component supports a maximum operating temperature of +150 °C and has a power dissipation rating of 125 mW.

Procurement Notes

Verify the specific ordering suffix and revision status directly with Panasonic Industry before finalizing procurement plans. Confirm RoHS compliance details and check for any product change notifications or discontinuation notices that may affect long-term supply availability for production runs.

Selection Notes

Select this component when a PNP configuration with integrated biasing is required to reduce external component count. Ensure the 50 V voltage rating and 100 mA current capacity meet the load requirements. Verify that the SSMini3 F3 B footprint aligns with the PCB layout constraints and soldering process capabilities.

Part Context

This part belongs to Panasonic's series of pre-biased transistors designed to replace discrete resistor-transistor combinations. These devices are engineered to save board space and simplify assembly processes in modern electronic equipment. The DRA5144T0L specifically addresses applications needing reliable PNP switching with minimal external passive components.

Replacement Considerations

Check for direct substitutes within the Panasonic DRA series with identical pinouts and electrical characteristics. Verify compatibility with alternative manufacturers' PNP digital transistors in the SSMini3 F3 B package, ensuring matching VCEO, IC, and hFE specifications.
