DDA124EU-7-F

Overview

The DDA124EU-7-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates built-in biasing resistors within a compact SOT363 package. The device operates with a collector-emitter breakdown voltage of -50 V and supports a continuous collector current of -100 mA. Each internal transistor includes nominal input (R1) and output (R2) resistors of 22 kΩ, providing a resistance ratio of 1. Power dissipation is rated at 200 mW, with a gain-bandwidth product of 250 MHz. The component is fully RoHS compliant and halogen-free.

Feature Summary

• Integrates two independent PNP transistors with built-in biasing resistors to simplify circuit design.
• Utilizes epitaxial planar die construction for reliable performance in surface-mount applications.
• Manufactured using environmentally compliant materials that are lead-free, halogen-free, and antimony-free.

Applications

• General-purpose switching circuits requiring dual PNP control.
• Driver stages for logic-to-analog signal interfacing.
• Automotive electronics applications meeting AEC-Q101 qualification standards.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging quantity and carrier type. Confirm compliance requirements such as RoHS 3 or automotive AEC-Q101 status if applicable to the target application. Ensure the source channel is authorized to guarantee product authenticity and traceability.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required in a small footprint. Compare the 22 kΩ resistor values against alternative models like the DDC124EU-7-F for NPN equivalents. Evaluate thermal resistance and power dissipation limits relative to the expected ambient temperature and PCB pad layout constraints.
