Overview
The DDTA143TKA-7-F is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in an SC-59 package. The device integrates a single built-in bias resistor (R1) with a nominal value of 4.7 kΩ. Key electrical ratings include a collector-emitter voltage (VCEO) of -50 V, a collector current (IC) of -100 mA, and power dissipation (Pd) of 200 mW. The DC current transfer ratio (hFE) ranges from 100 to 600 at IC = -1 mA. Operating and storage temperatures span from -55°C to +150°C.
Feature Summary
- Integrates a single built-in bias resistor for simplified circuit configuration
- Utilizes epitaxial planar die construction for reliability
- Available in a compact SC-59 surface mount case
Applications
- Inverter circuits requiring external input resistors elimination
- Switching applications within specified voltage and current limits
- General-purpose digital logic interfacing
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm RoHS compliance status based on manufacturing date codes, as green molding compound usage varies by production batch. Ensure the component meets environmental requirements for the intended application before procurement.
Selection Notes
Select this component when a PNP pre-biased transistor with a 4.7 kΩ internal resistor is required. Verify that the -50 V voltage rating and -100 mA current capacity align with the circuit design parameters. Consider the SC-59 package dimensions for PCB layout constraints.
Part Context
This part belongs to the DDTA R1-only series from Diodes Incorporated. It is designed as a complementary counterpart to NPN types within the same family. The device simplifies biasing networks by incorporating internal resistance, reducing component count in digital switching applications.
Replacement Considerations
Complementary NPN types are available within the same product family. Verify pinout compatibility and electrical specifications before substituting with other manufacturers' equivalents.
