DDA143TU-7-F

Overview

The DDA143TU-7-F is a PNP pre-biased dual transistor manufactured by Diodes Incorporated, housed in an SOT363 package. It integrates two NPN transistors with built-in biasing resistors (R1 = 4.7kΩ nominal). Key electrical parameters include a collector-emitter breakdown voltage (BVCEO) of -50V and a continuous collector current (IC) of -100mA. The device supports a power dissipation of 200mW at +25°C and operates within a temperature range of -55°C to +150°C. It features a minimum DC current gain (hFE) of 100 and a gain-bandwidth product of 250MHz.

Feature Summary

• Integrates dual PNP transistors with built-in biasing resistors for simplified circuit design
• Utilizes epitaxial planar die construction for reliable performance
• Compliant with RoHS standards and halogen/antimony-free green device specifications

Applications

• General-purpose switching applications requiring dual transistor functionality
• Driver circuits for low-power loads
• Logic interface circuits for level shifting or buffering

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the standard 3,000-unit reel packaging configuration as listed in the manufacturer's official documentation. Confirm that the component status remains 'Active' prior to finalizing procurement plans, as manufacturing statuses are subject to change without notice.

Selection Notes

Select this component when a dual PNP configuration with integrated biasing is required in a compact SOT363 footprint. Ensure the application voltage does not exceed the -50V collector-emitter breakdown rating and that the total power dissipation remains within the 200mW limit under expected operating conditions.

Part Context

This part belongs to the DDA series of pre-biased dual transistors from Diodes Incorporated. It shares the same SOT363 package and general electrical characteristics as other variants in the family, distinguished primarily by the specific resistance values of the internal biasing network.

Replacement Considerations

Direct pin-compatible replacements within the same series include DDA143TUQ-7-F. Verify that any substitute maintains identical resistor tolerances and electrical ratings to ensure circuit compatibility.
