Overview
The DDTA143TCA-7 is a PNP pre-biased transistor from the R1-only series, housed in an SOT23 package. It integrates a single internal biasing resistor (R1) with a nominal value of 4.7 kΩ. The device features epitaxial planar die construction and operates within a temperature range of -55°C to +150°C. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1mA and VCE = -5V.
Feature Summary
- Integrates a single built-in biasing resistor (R1 only) to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable performance.
- Complementary NPN types are available within the same product family.
Applications
- Switching applications requiring simplified base drive circuits.
- Driver stages for logic interfaces.
- General-purpose amplification where fixed biasing is sufficient.
Procurement Notes
Verify the specific ordering suffix against official documentation, as it determines packaging details such as reel size and tape width. Confirm RoHS compliance status and manufacturing origin requirements prior to procurement. Ensure availability aligns with project timelines by checking current production status.
Selection Notes
Select this component when a PNP pre-biased transistor with a 4.7 kΩ base resistor is required. Verify that the -50 V collector-emitter voltage and -100 mA current ratings meet the application's maximum operating conditions. Consider the SOT23 package dimensions for PCB layout constraints.
Part Context
This part belongs to the DDTA (R1-only series) CA line manufactured by Diodes Incorporated. The series offers various resistor values, distinguished by the middle digits in the part number. The 'CA' suffix indicates the SOT23 package type. This specific model provides a 4.7 kΩ internal resistor configuration.
Replacement Considerations
Direct substitutes within the same manufacturer's lineup include other variants from the DDTA1xxTCA series with different resistor values. Cross-manufacturer replacements must match the SOT23 footprint, PNP polarity, and equivalent electrical parameters such as VCEO and IC ratings.
