DDTC115GE-7

Overview

The DDTC115GE-7-F is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrates a single built-in biasing resistor (R2) with a nominal value of 100 kΩ. The device is housed in a compact SOT-523 package, measuring approximately 1.6 mm x 1.6 mm x 0.75 mm. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 50 V, a continuous collector current (IC) of 100 mA, and a power dissipation (PD) of 150 mW at 25°C ambient temperature. The component operates within a temperature range of -55°C to +150°C and meets AEC-Q101 standards for high reliability.

Feature Summary

• Integrates a single built-in 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 standards, ensuring suitability for automotive applications requiring high reliability.
• Manufactured as a totally lead-free, halogen-free, and antimony-free 'Green' device compliant with RoHS directives.

Applications

• Automotive electronic systems due to AEC-Q101 qualification.
• General-purpose switching and amplification in consumer electronics.
• Driver circuits for LEDs or low-power loads where integrated biasing reduces component count.
• Interface logic level shifting between microcontrollers and peripheral devices.

Procurement Notes

Verify the specific ordering suffix '-7-F' when sourcing, as it indicates the reel size and tape width configuration (7-inch reel, 8mm tape, 3,000 units per reel). Confirm compliance requirements such as RoHS 3 and 'Green' status directly with the manufacturer's documentation, as these attributes are tied to the specific part number designation. Ensure the procurement channel is authorized to guarantee product authenticity and traceability.

Selection Notes

Select the DDTC115GE-7-F when a single integrated biasing resistor (R2) is required rather than dual resistors found in other series. The 100 kΩ nominal R2 value suits applications needing moderate base drive current. Compare the 150 mW power dissipation limit against thermal constraints in the final assembly. Consider the SOT-523 footprint dimensions if space is limited, noting its compatibility with standard surface mount placement processes.

Part Context

This component belongs to the DDTC (R2-ONLY SERIES) E family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor with only the R2 resistor integrated. Complementary PNP types are available in the DDTA series. The 'E' in the model name denotes the SOT-523 package variant, distinguishing it from other package options like SOT-23 or SOT-323 found in different series.

Replacement Considerations

Direct substitutes must match the NPN polarity, 50V VCEO rating, 100mA IC, 100kΩ R2 resistor, and SOT-523 package. Verify that alternative manufacturers offer components with equivalent thermal resistance and AEC-Q101 qualification if automotive use is intended. Check for identical marking codes (N29) if visual inspection is required for assembly verification.
