Overview
The DDTC144GE-7-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, featuring epitaxial planar die construction. It integrates a single built-in biasing resistor (R2) with a nominal value of 47 kΩ. The device operates within a collector-emitter voltage range up to 50 V and supports a continuous collector current of 100 mA. Maximum power dissipation is rated at 150 mW, with an operating temperature range spanning -55°C to +150°C. The component utilizes a SOT523 package and meets AEC-Q101 standards for high reliability.
Feature Summary
- Integrates a single built-in biasing resistor (R2 only) to simplify circuit design
- Qualified to AEC-Q101 standards for automotive and high-reliability applications
- Utilizes epitaxial planar die construction for robust performance
- Compliant with RoHS directives and defined as halogen and antimony free
Applications
- Automotive electronic systems requiring qualified components
- General-purpose switching circuits utilizing pre-biased configurations
- High-reliability surface mount applications in compact form factors
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the 3,000-unit reel quantity per the manufacturer's ordering information. Confirm compliance requirements such as AEC-Q101 qualification and RoHS status against the latest datasheet revision DS30316 Rev. 9-2 before procurement.
Selection Notes
Select this component when a single NPN pre-biased transistor with a 47 kΩ base resistor is required. Ensure the application voltage does not exceed the 50 V collector-emitter rating and that the thermal constraints fit within the 150 mW dissipation limit for the SOT523 package.
Part Context
This part belongs to the DDTC (R2-ONLY SERIES) E family from Diodes Incorporated. It is specifically designed as an NPN pre-biased transistor, distinct from complementary PNP types like the DDTA series. The 'GE' suffix indicates the SOT523 package variant within this product line.
Replacement Considerations
Direct substitutes within the same series include DDTC114GE-7-F, DDTC124GE-7-F, and DDTC115GE-7-F, which share identical packaging and electrical characteristics but differ in the nominal R2 resistance values.
