Overview
The DDTA124GE-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and includes a built-in shunt biasing resistor (R2) with a nominal value of 22 kΩ. The device operates within a collector-emitter voltage range of -50 V and supports a continuous collector current of up to 100 mA, with a maximum power dissipation of 150 mW. Packaged in the SOT-523 form factor, it offers a gain-bandwidth product of 250 MHz and functions reliably across an operating temperature range from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single shunt biasing resistor (R2 only)
- Qualified to AEC-Q101 standards for high reliability applications
Applications
- Switching circuits requiring integrated base biasing
- Driver stages for logic-to-analog interface conversion
- Automotive electronics compliant with AEC-Q101 standards
Procurement Notes
Verify component authenticity through authorized distribution channels to ensure compliance with RoHS 3 and lead-free specifications. Confirm that the ordering suffix matches the required reel size and tape width parameters. Validate date code markings against manufacturing records to ensure traceability and adherence to quality standards during procurement processes.
Selection Notes
Select this component when a PNP configuration with a specific 22 kΩ internal shunt resistor is required. Ensure the circuit design accommodates the -50 V collector-emitter breakdown voltage limit. Verify that the SOT-523 package dimensions align with the PCB footprint requirements and that the thermal resistance characteristics meet the system's heat dissipation needs under maximum load conditions.
Part Context
This part belongs to the DDTA (R2-ONLY SERIES) E family, which provides various resistor values for different biasing needs. Complementary NPN types are available within the DDTC series. The 'E' designation indicates the specific R2-only resistor configuration, while the '-7-F' suffix denotes the standard 3000-unit reel packaging format compliant with environmental directives.
