DDA144EU-7

Overview

The DDA144EU-7 is a PNP pre-biased dual transistor in an SOT363 package. It features built-in biasing resistors with nominal values of R1 = 47kΩ and R2 = 47kΩ. The device has a supply voltage rating of -50V, a continuous collector current of -100mA, and a power dissipation of 200mW. It operates within a temperature range of -55°C to +150°C and includes epitaxial planar die construction.

Feature Summary

• Epitaxial planar die construction
• Built-in biasing resistors
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free

Applications

• Automotive applications requiring specific change control (Q suffix only)
• General-purpose digital switching
• Driver circuits for low-power loads

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation before procurement. The base model number may correspond to multiple variants with different packaging or automotive qualifications. Confirm availability status directly with authorized distributors as product lifecycle stages can change without notice.

Selection Notes

Select this component when a compact PNP dual transistor solution with integrated biasing is required. Ensure the negative polarity requirements match the circuit design. For automotive applications, verify if the Q-suffix variant is necessary for AEC-Q101 qualification and PPAP capability.

Part Context

This part belongs to the DDA (XXXX) U series of PNP pre-biased dual transistors manufactured by Diodes Incorporated. It is designed to replace discrete resistor networks and single transistors, saving board space. The complementary NPN version is available in the DDC series.

Replacement Considerations

Direct substitutes include other PNP pre-biased dual transistors in SOT363 packages with similar resistor values (-47kΩ/-47kΩ). Verify pinout compatibility and electrical ratings such as VCEO and IC(max) before substitution.
