DDTA123YE-7-F

Overview

The DDTA123YE-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates internal biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 10 kΩ. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning from -55°C to +150°C. It is housed in a compact SOT-523 package.

Feature Summary

• Integrates built-in biasing resistors (R1≠R2) to reduce printed circuit board space and simplify circuit design.
• Constructed using epitaxial planar die technology for reliable performance.
• Qualified to AEC-Q101 standards to ensure high reliability for automotive applications.
• Manufactured as a totally lead-free and fully RoHS compliant device.

Applications

• Automotive electronic systems requiring high-reliability switching components.
• General-purpose digital switching circuits utilizing surface mount technology.
• Driver stages for logic interfaces where integrated biasing simplifies the schematic.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required packaging specifications. Ensure compliance with relevant environmental directives such as RoHS 3 and REACH before integration into final assemblies.

Selection Notes

Select this component when a PNP configuration with specific unequal biasing resistor ratios is required. Verify that the maximum input voltage limits align with the system's logic levels. Consider the thermal resistance characteristics if the application involves high ambient temperatures or limited airflow.

Part Context

This part belongs to the DDTA series of pre-biased transistors produced by Diodes Incorporated. The series offers various combinations of base and emitter resistors to accommodate different drive requirements. The DDTA123YE variant specifically provides a 2.2 kΩ base resistor and a 10 kΩ emitter resistor.

Replacement Considerations

Direct substitutes include other DDTA123YE variants from the same manufacturer. Cross-brand equivalents may exist but require verification of pinout compatibility and electrical parameter alignment.
