DDA144EU-7-F

Overview

The DDA144EU-7-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated. It utilizes epitaxial planar die construction and integrates built-in biasing resistors within an SOT363 package. The device features nominal resistor values of R1 = 47 kΩ and R2 = 47 kΩ. Key electrical specifications include a supply voltage (VCC) rating of -50 V, a maximum collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW. The gain-bandwidth product (fT) is typically 250 MHz at VCE = -10 V and IE = -5 mA. Operating temperature ranges from -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction with integrated biasing resistors for simplified circuit design.
• Totally lead-free and fully RoHS compliant, halogen and antimony free "Green" device.
• Suitable for automotive applications requiring specific change control; AEC-Q101 qualified and PPAP capable.

Applications

• Automotive electronics systems requiring AEC-Q101 qualification.
• General-purpose switching and amplification circuits utilizing PNP logic interfaces.
• Digital-to-analog conversion stages or level shifting applications in compact surface-mount designs.

Procurement Notes

Verify the component status as Active before procurement. Confirm that the ordering suffix matches the required reel size and tape width specifications. Ensure compliance with environmental directives including RoHS 2, RoHS 3, and Halogen/Antimony-free definitions. Validate that the selected packaging carrier aligns with automated assembly requirements.

Selection Notes

Select this part when a PNP configuration with 47kΩ input and emitter resistors is required. Compare against the complementary NPN type DDC144EU if both polarities are needed. Verify that the -50V supply voltage and -100mA output current meet the application's absolute maximum ratings. Consider thermal resistance constraints for high ambient temperatures.

Part Context

This component belongs to the DDA (XXXX) U series of PNP pre-biased dual transistors. It shares the SOT363 package and manufacturing process with other variants differing primarily in resistor ratios. The series offers complementary NPN types under the DDC designation. All parts utilize epitaxial planar construction and are designed for surface-mount technology applications.

Replacement Considerations

Direct replacement options include other DDA series variants with matching resistor values. For NPN equivalents, consider the DDC144EU series. Verify pinout compatibility and electrical parameters before substitution. NRND parts like DDA114YUQ suggest using ADA114YUQ instead.
