Overview
The DDTA143ZE-7 is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT523 package. It integrates internal biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage (VCC) of -50 V and a continuous output current (IO) of -100 mA. Power dissipation is rated at 150 mW, with an operating temperature range spanning from -55°C to +150°C. The component features a gain-bandwidth product (fT) of 250 MHz and a minimum DC current gain (hFE) of 80.
Feature Summary
- Integrates two built-in biasing resistors (R1 ≠ R2) for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Qualified to AEC-Q101 standards for high reliability applications
Applications
- Switching circuits requiring integrated base drive components
- Driver stages for logic interfaces
- General-purpose amplification in portable electronics
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as '-7-F' may indicate different packaging or compliance markings compared to the base model. Confirm RoHS status and lead-free certification requirements prior to procurement. Ensure compatibility with moisture sensitivity level 1 handling procedures during assembly.
Selection Notes
Select this component when a compact PNP solution with fixed internal resistance ratios is required. The SOT523 package offers space efficiency for dense layouts. Verify that the -100 mA current rating and -50 V voltage limits align with the target application's electrical demands.
Part Context
This part belongs to the DDTA (R1≠R2 Series) E family of pre-biased transistors. Complementary NPN types are available within the DDTC series. The device is designed for surface mount technology and utilizes molded plastic 'Green' compound casing.
Replacement Considerations
Direct substitutes include other DDTA143ZE variants from Diodes Incorporated. Cross-manufacturer equivalents should be verified for matching resistor values (4.7k/47k), polarity, and package dimensions.
