DRC3144T0L

Overview

The DRC3144T0L is a single NPN pre-biased bipolar transistor manufactured by Panasonic Electronic Components. It integrates an internal base resistor to simplify circuit design and reduce component count. The device features a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current rating of -100 mA. It is housed in the SSSMini3-F2-B surface-mount package, which measures 1.2x1.2 mm. The unit supports operation at temperatures up to +150°C and is available in reel, cut tape, and MouseReel packaging formats.

Procurement Notes

Verify the specific suffix and marking code against the official Panasonic datasheet to ensure compatibility with the required electrical parameters. Confirm that the supplier provides genuine components with traceable documentation. Check for RoHS compliance status as indicated in the product specifications. Ensure the packaging format matches the production requirements. Validate the component's availability status prior to finalizing procurement plans.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The SSSMini3-F2-B package offers a small footprint suitable for high-density PCB layouts. Consider the -50 V voltage rating and -100 mA current capacity for appropriate signal levels. Evaluate the thermal performance relative to the application's operating temperature range. Compare the internal resistance values against the driving source requirements.
