Overview
The DDTA143FE-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in an SOT523 package. The device integrates two internal biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 22 kΩ. Key electrical specifications include a maximum supply voltage (VCC) of -50 V, a continuous output current (IC) of -100 mA, and a power dissipation rating of 150 mW. The component operates within a temperature range of -55°C to +150°C and meets AEC-Q101 standards for high reliability.
Feature Summary
- Integrates dual biasing resistors with unequal resistance values (R1 ≠ R2) to simplify circuit design.
- Constructed using epitaxial planar die technology for enhanced performance.
- Qualified to AEC-Q101 automotive standards ensuring high reliability.
- Compliant with RoHS 3 directives and defined as halogen-free and antimony-free.
Applications
- Switching applications requiring integrated base drive resistors.
- Automotive electronics systems adhering to AEC-Q101 requirements.
- General-purpose digital logic interfacing and level shifting.
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation, as variations such as -7-F may indicate different packaging configurations like tape and reel quantities. Confirm compliance status including RoHS 3 and lead-free definitions directly from the official datasheet or manufacturer quality statements prior to procurement.
Selection Notes
Select this component when a PNP configuration with specific 4.7 kΩ and 22 kΩ internal resistor ratios is required. Ensure the SOT523 package dimensions fit the PCB layout constraints. Verify that the -50 V collector-emitter voltage and -100 mA current ratings exceed the maximum operational loads in the target application circuit.
Part Context
This part belongs to the DDTA(R1≠R2 Series) E family of pre-biased transistors from Diodes Incorporated. It serves as the PNP counterpart to the DDTC series NPN devices. The 'E' designation typically denotes specific electrical characteristics or packaging variants within this product line.
Replacement Considerations
Direct functional substitutes within the same resistor ratio family include DDTA143XE (4.7k/10k) and DDTA143ZE (4.7k/47k). For complementary NPN applications, consider the DDTC143FE model. Verify pinout compatibility and thermal resistance parameters when substituting.
