Overview
The DDTA144VCA-7 is a single PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It integrates internal biasing resistors with R1 at 47 kΩ and R2 at 10 kΩ. The device supports a maximum collector-emitter voltage of -50 V and a continuous collector current of -100 mA. Electrical characteristics include a minimum DC current gain (hFE) of 33 and a transition frequency of 250 MHz. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated biasing resistors simplify circuit design
- Surface-mount package optimized for automated assembly
Applications
- General-purpose switching applications
- Driver circuits for loads requiring base current limiting
- Logic interface circuits between microcontrollers and peripheral devices
Procurement Notes
Verify the specific ordering suffix when sourcing components. The official datasheet lists the orderable part number as DDTA144VCA-7-F. Confirm that the received component matches this designation to ensure correct packaging and resistance values. Cross-reference manufacturer documentation directly rather than relying solely on distributor descriptions to avoid discrepancies in part identification.
Selection Notes
Select this component for designs requiring a compact PNP solution with built-in base resistance. The 47 kΩ input resistor value determines the drive current requirements from the preceding logic stage. Ensure the application voltage does not exceed the -50 V rating and that thermal constraints allow for 200 mW dissipation within the specified ambient temperature limits.
Part Context
This component belongs to the DDTA (R1≠R2 SERIES) CA family of 50V PNP pre-biased transistors. It serves as the complementary counterpart to the DDTC NPN series. The 'CA' suffix indicates compliance with RoHS directives and halogen-free manufacturing standards. The device is designed for high-volume production environments utilizing standard SMT processes.
Replacement Considerations
Direct functional substitutes within the same family include DDTA144WCA-7-F, which features different internal resistor ratios (47 kΩ / 22 kΩ). Verify that alternative parts match the required hFE and voltage ratings before implementation.
