Overview
The DDTA144VE-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates internal biasing resistors with nominal values of R1 = 47 kΩ and R2 = 10 kΩ. The device operates within a supply voltage range up to -50 V and supports a continuous collector current of -100 mA. It is housed in a compact SOT-523 package, weighs approximately 0.002 grams, and complies with AEC-Q101 standards for high reliability.
Feature Summary
- Epitaxial planar die construction
- Integrated unequal biasing resistors (R1≠R2)
- Qualified to AEC-Q101 automotive standards
Applications
- Automotive electronic circuits requiring high reliability
- General-purpose switching applications
- Driver circuits for small signal loads
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations such as -7-F indicate RoHS compliance and reel packaging specifications. Confirm that the component meets environmental directives including RoHS 3 and halogen-free requirements before integration into final assemblies.
Selection Notes
Select this component when a PNP configuration with integrated base and emitter resistors is required to simplify circuit design. Ensure the application voltage does not exceed the -50 V limit and that the thermal resistance characteristics are suitable for the intended ambient temperature conditions.
Part Context
This part belongs to the DDTA (R1≠R2 Series) E family from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The 'E' designation indicates compliance with automotive reliability standards, distinguishing it from standard commercial grade variants within the same resistor ratio family.
