Overview
The DDTA124ECA-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction with built-in biasing resistors where R1 equals R2, nominally 22kΩ. The device operates within a supply voltage range of -50V and supports a continuous collector current of -100mA. Power dissipation is rated at 200mW with a thermal resistance of 625°C/W. It functions across an operating temperature range of -55°C to +150°C and includes a gain-bandwidth product of 250MHz.
Feature Summary
- Epitaxial planar die construction with integrated equal-value biasing resistors
- Qualified to AEC-Q101 standards for high reliability applications
- Totally lead-free and fully RoHS compliant with halogen and antimony free green device composition
Applications
- Automotive electronic circuits requiring AEC-Q101 qualification
- General purpose switching applications utilizing surface mount technology
- Driver circuits for logic level translation or interface buffering
Procurement Notes
Verify the specific ordering suffix when sourcing components. The official datasheet lists the -7-F variant as active; confirm that the requested part number matches the exact suffix required for your manufacturing process. Ensure compliance with automotive PPAP requirements if applicable to your production line specifications.
Selection Notes
Select this component for designs requiring a compact PNP solution with integrated base and emitter resistors. Verify that the 22kΩ nominal resistance aligns with your drive current requirements. Confirm that the SOT23 package dimensions fit your PCB layout constraints and that the 200mW power rating accommodates your thermal management strategy.
Part Context
This component belongs to the DDTA (R1 = R2) series of pre-biased transistors from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The device is designed to simplify circuit design by replacing discrete resistor networks with a single surface-mount package, reducing board space and assembly complexity.
Replacement Considerations
Consult the manufacturer's documentation for direct equivalents. Complementary NPN types are available in the DDTC series. Verify pinout compatibility and electrical parameters before substituting with components from other manufacturers.
