DRA2123Y0L

Overview

The Panasonic DRA2123Y0L is a digital transistor with built-in bias resistors, manufactured by ROHM Semiconductor under the Panasonic Electronic Components brand. It features a PNP configuration housed in an EMT3F surface-mount package measuring 1.6x1.6mm. The device provides a collector current of -100mA and a collector-emitter voltage of -50V. This component integrates two transistors and one resistor within a single compact footprint to simplify circuit design.

Feature Summary

• Compact SMD Package: Integrates dual transistors and a bias resistor in a small 1.6x1.6mm footprint for space-constrained designs.
• High Voltage Rating: Supports a collector-emitter voltage of -50V suitable for various switching applications.
• Integrated Circuitry: Combines PNP transistors with built-in bias resistors to reduce external component count.

Applications

• General-purpose signal switching
• Driver circuits for low-current loads
• Logic level translation

Procurement Notes

Verify the manufacturer designation carefully, as this part number is produced by ROHM Semiconductor despite the Panasonic branding. Confirm the specific suffix 'Y0L' matches the required EMT3F package and electrical characteristics. Check for end-of-life status or alternative sourcing options due to potential supply chain variations.

Selection Notes

Select this component when a compact PNP digital transistor solution is required for low-voltage switching. Ensure the -100mA current rating meets the load requirements. Compare against standard discrete transistor plus resistor combinations to evaluate space savings and assembly efficiency benefits.

Part Context

This component belongs to the family of digital transistors with built-in bias resistors. These devices are designed to replace multiple discrete components, simplifying PCB layout and reducing assembly costs. The Panasonic Electronic Components line utilizes ROHM's manufacturing capabilities for these specific semiconductor devices.

Replacement Considerations

The DTA123YEBTL is a confirmed substitute part number listed in public documentation. Verify pin compatibility and electrical specifications before replacement.
