Overview
The DDTC113ZCA-7 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction and integrated biasing resistors with nominal values of R1 = 1 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. Power dissipation is rated at 200 mW, with a thermal resistance (junction to ambient) of 625 °C/W. The transition frequency is typically 250 MHz. It is housed in a SOT-23 package, complies with AEC-Q101 standards, and is fully RoHS compliant.
Feature Summary
- Integrated biasing resistors with unequal ratios for simplified circuit design
- Qualified to AEC-Q101 standards for high reliability applications
- Totally lead-free and halogen/antimony free green device construction
Applications
- Switching applications requiring built-in base biasing
- Driver circuits for low-power loads
- Logic interface level shifting
Procurement Notes
Verify the specific ordering suffix against official documentation, as standard products may differ from automotive qualified variants. Confirm compliance requirements such as PPAP capability if used in automotive contexts. Ensure the component matches the exact marking code and reel specifications defined in the manufacturer's ordering information table.
Selection Notes
Select this component when an NPN configuration with specific internal resistor ratios is required. Verify that the 1 kΩ input resistor and 10 kΩ emitter resistor values align with the target drive current and logic levels. Consider the 50 V maximum supply voltage and 100 mA output current limits during circuit design.
Part Context
This part belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It serves as the NPN counterpart to the DDTA series PNP devices. The 'CA' designation indicates the specific resistor ratio and package type. It is electrically compatible with other members of the DDTC11x series sharing the same pinout and general characteristics.
Replacement Considerations
Direct substitutes include other Diodes Incorporated parts from the DDTC11x series with matching resistor values. Complementary PNP equivalents are available in the DDTA11x series. Cross-manufacturer replacements must match the SOT-23 package, 50V rating, 100mA current, and 1kΩ/10kΩ resistor network.
