Overview
The DDTA114WCA-7 is a single PNP pre-biased transistor from the DDTA (R1≠R2 SERIES) CA family, manufactured by Diodes Incorporated. It integrates biasing resistors into an SOT-23 surface-mount package. Key electrical parameters include a supply voltage of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW. The device features a typical input resistor (R1) of 10 kΩ and a secondary resistor (R2) of 4.7 kΩ. Minimum DC current gain is specified at 24, with a gain-bandwidth product of 250 MHz. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction with built-in biasing resistors for simplified circuit design.
- Surface-mount SOT-23 package optimized for automated assembly processes.
- Totally lead-free and fully RoHS compliant, halogen and antimony free.
Applications
- General-purpose switching applications requiring integrated biasing.
- Automotive electronics utilizing AEC-Q100/101 qualified components.
- High-frequency signal processing circuits up to 250 MHz.
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm datasheet revision DS30334 Rev. 8-2 matches physical markings. Ensure compliance with specific automotive quality standards if required for the target application environment.
Selection Notes
Select this model when a PNP configuration with R1=10kΩ and R2=4.7kΩ is required. Verify that the -50V supply rating and -100mA current capacity meet system demands. Consider thermal resistance of 625 °C/W for heat dissipation planning in enclosed designs.
Part Context
Part of the DDTA (R1≠R2 SERIES) CA family offering various resistor combinations. Complementary NPN types are available in the DDTC series. Manufactured in IATF 16949 certified facilities for automotive-grade reliability.
Replacement Considerations
DDTA114YCA-7-F offers different resistor values (10kΩ/47kΩ). DDTA114ECAQ-13 provides higher power dissipation (310mW) and AEC-Q101 qualification in SOT-23. Verify pinout compatibility and electrical limits before substitution.
