Overview
The DDTB142JU-7 is a PNP pre-biased surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates built-in biasing resistors within a SOT-323 molded plastic package. The device supports a maximum collector current of -500 mA and a power dissipation of 200 mW at 25°C ambient temperature. Key electrical characteristics include a collector-emitter breakdown voltage (BVCEO) of -40 V, a collector-base breakdown voltage (BVCBO) of -50 V, and a minimum DC current gain (hFE) of 56. The typical input resistor R1 is 470 Ohms with an R2 value of 10 kOhms.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design
- Utilizes epitaxial planar die construction for reliability
- Available in lead-free, RoHS compliant packaging
Applications
- General purpose switching applications

- Logic interface buffering
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation before procurement. Confirm that the component meets all required environmental standards and packaging specifications for the intended application. Cross-reference the part number with the latest datasheet revisions to ensure compatibility with existing designs.
Selection Notes
Select this component when a compact PNP solution with integrated biasing is required. Ensure the operating voltage does not exceed the -40 V collector-emitter breakdown limit. Verify that the thermal resistance and power dissipation capabilities are sufficient for the expected ambient temperature conditions and load currents.
Part Context
This component belongs to the DDTB series of PNP pre-biased transistors from Diodes Incorporated. It is designed as a complementary counterpart to NPN types within the same family. The series offers various resistor configurations to accommodate different logic levels and drive requirements in space-constrained electronic designs.
Replacement Considerations
Check for direct replacements such as DDTB142TU-7 or DDTB142LU-7 if resistor values differ. Verify pinout compatibility and electrical ratings before substituting with components from other manufacturers.
