DDTA115GE-7-F

Overview

The DDTA115GE-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, belonging to the DDTA (R2-ONLY SERIES) E family. It features an epitaxial planar die construction housed in an SOT523 package. The device integrates a single shunt biasing resistor with a nominal value of 100 kΩ. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning from -55°C to +150°C. The component meets AEC-Q101 standards for high reliability and is fully RoHS compliant.

Feature Summary

• Integrates a built-in shunt biasing resistor (R2 only) to simplify circuit design and reduce board space.
• Constructed using epitaxial planar die technology for robust performance.
• Qualified to AEC-Q101 automotive standards ensuring high reliability.
• Manufactured as a totally lead-free, halogen-free, and antimony-free "Green" device.

Applications

• Switching applications requiring integrated base biasing.
• Automotive electronics systems adhering to AEC-Q101 requirements.
• General-purpose digital switching circuits utilizing PNP logic levels.
• Driver stages for low-current loads where simplified bias networks are preferred.

Procurement Notes

Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging details such as reel size and tape width. Ensure compliance requirements match project specifications, particularly regarding RoHS 3 and halogen-free status. Confirm that the SOT523 package dimensions align with the intended PCB footprint layout before finalizing procurement orders.

Selection Notes

Select this component when a PNP transistor with an integrated 100 kΩ shunt resistor is required. The SOT523 package offers a compact solution for space-constrained designs. Consider the -50 V voltage rating and -100 mA current limit to ensure adequate headroom for the target application. Verify thermal management needs against the 150 mW power dissipation rating under expected ambient conditions.

Part Context

This part belongs to the DDTA series of pre-biased transistors manufactured by Diodes Incorporated. The 'E' designation indicates the R2-only configuration, distinguishing it from variants with dual resistors or different configurations. The GE suffix typically denotes the SOT523 package type within this product line.

Replacement Considerations

Complementary NPN types are available within the same series, specifically the DDTC family. When substituting, verify that the replacement component matches the required polarity, resistor values, and package dimensions. Ensure any alternative part meets the same AEC-Q101 qualification if automotive reliability is mandated.
