Overview
The DDC114YUQ-7-F is a dual NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It integrates two NPN transistors with built-in biasing resistors (R1 = 10 kΩ, R2 = 47 kΩ) in an SOT-363 package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current of 70 mA per element. It operates within a temperature range of -55°C to +150°C and has a power dissipation rating of 200 mW. The component is AEC-Q101 qualified for automotive applications.
Feature Summary
- Dual NPN configuration with integrated biasing resistors
- AEC-Q101 qualified for automotive use
- Totally lead-free and fully RoHS compliant
Applications
- Automotive electronic circuits requiring specific change control
- General purpose switching applications
- Driver circuits for logic interfaces
Procurement Notes
Verify the ordering suffix 'Q' against the manufacturer's official documentation before procurement. The datasheet explicitly lists this part number as Not Recommended for New Design (NRND). Confirm that the intended application does not require new design approval, as the recommended replacement is ADC114YUQ.
Selection Notes
Select this component only if existing designs utilize the NRND status without modification constraints. For new designs, the manufacturer recommends using ADC114YUQ instead. Ensure the required resistor ratio matches the 10 kΩ base and 47 kΩ emitter configuration specified for the DDC114YU series.
Part Context
This component belongs to the DDC(XXXX)U family of NPN pre-biased dual transistors from Diodes Incorporated. The 'U' suffix indicates the SOT-363 package type. The 'Q' suffix typically denotes automotive qualification, aligning with the AEC-Q101 standard mentioned in the product features section of the datasheet.
Replacement Considerations
The datasheet identifies ADC114YUQ as the direct replacement for DDC114YUQ-7-F due to its NRND status. Verify pinout compatibility and electrical specifications between the legacy DDC part and the recommended ADC substitute.
