Overview
The DDTC144VCA-7 is an NPN pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features epitaxial planar die construction with built-in biasing resistors, specifically R1 at 47 kOhms and R2 at 10 kOhms. The device operates within a supply voltage range of up to 50 V and supports a continuous collector current of 100 mA. It is housed in a SOT-23 package with a power dissipation rating of 200 mW. The component is designed for high reliability, meeting AEC-Q101 standards, and is fully RoHS compliant.
Feature Summary
- Epitaxial planar die construction with integrated biasing resistors
- Qualified to AEC-Q101 standards for automotive applications
- Totally lead-free and fully RoHS compliant
- Halogen and antimony free green device
Applications
- Automotive electronics requiring high reliability components
- General-purpose switching applications
- Driver circuits for low-power loads
Procurement Notes
Verify the specific ordering suffix when sourcing this component. The base model DDTC144VCA-7 may be discontinued or replaced by updated versions such as DDTC144VCA-7-F. Confirm availability directly with authorized distributors or the manufacturer to ensure compliance with current production status and packaging requirements.
Selection Notes
Select this component for designs requiring an NPN digital transistor with a 47 kOhm base resistor and 10 kOhm emitter resistor. Ensure the application voltage does not exceed the 50 V maximum rating. Verify that the SOT-23 package dimensions fit the PCB layout constraints and that the thermal resistance characteristics are suitable for the expected ambient temperature conditions.
Part Context
This part belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It is distinct from other variants in the series by its specific resistor values of 47 kOhms and 10 kOhms. The 'CA' suffix indicates the standard product line configuration, while the '-7' denotes the reel size and tape width specifications for automated assembly.
Replacement Considerations
Direct replacement options include the DDTC144VCA-7-F variant. Other compatible parts within the same series with different resistor ratios should be evaluated carefully to ensure electrical compatibility.
