Overview
The DDTA144TCA-7 is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT23 package. It features a built-in base resistor (R1) with a nominal value of 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current (IC) of -100 mA. Power dissipation is rated at 200 mW, with a DC current gain (hFE) ranging from 100 to 600 at IC = -1 mA and VCE = -5 V. The transition frequency (fT) is typically 250 MHz. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single biasing resistor (R1 only) simplifies circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free "Green" device
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
Procurement Notes
Verify the specific ordering suffix against official documentation before procurement. The provided datasheet lists DDTA144TCA-7-F as the active orderable part number. Confirm that the required packaging quantity and carrier type match your production needs. Ensure compliance with RoHS 3 and REACH regulations if applicable to your region. Contact Diodes Incorporated directly for automotive qualification details or IATF 16949 certified facility requirements.
Selection Notes
Select this component when a PNP digital transistor with a 47 kΩ base resistor is required. Verify that the -50 V voltage rating and -100 mA current capacity meet the load requirements. Consider the SOT23 package dimensions for PCB layout constraints. Check the thermal resistance and power dissipation limits under actual operating conditions to ensure safe operation within the specified temperature range.
Part Context
This component belongs to the DDTA R1-only series from Diodes Incorporated. It is part of a family of pre-biased transistors available in various resistor values and configurations. Complementary NPN types are available in the DDTC series. The device is designed for surface-mount assembly and is suitable for high-volume manufacturing environments requiring compact, integrated switching solutions.
Replacement Considerations
Direct substitutes include other DDTA144 variants from Diodes Incorporated with matching electrical characteristics. Cross-manufacturer equivalents should be verified for pinout compatibility, voltage ratings, and resistor tolerance. Ensure any replacement maintains the same SOT23 package footprint and thermal performance.
