Overview
The DDTC143ZCAQ-13-F is an NPN pre-biased small signal surface mount transistor from Diodes Incorporated, housed in a SOT23 package. It features built-in biasing resistors with nominal values of R1 = 4.7 kΩ and R2 = 47 kΩ. The device is qualified to AEC-Q101 standards for high reliability and automotive applications. Key electrical ratings include a supply voltage (VCC) of 50 V, a maximum output current (IO) of 100 mA, and a power dissipation (PD) of 200 mW at +25°C. The DC current gain (hFE) has a minimum value of 80. Operating and storage temperatures range from -55°C to +150°C.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input resistors.
- Qualified to AEC-Q101 standards for high reliability and PPAP capable.
- Totally lead-free and fully RoHS compliant.
- Halogen and antimony free "Green" device.
Applications
- Automotive interface circuits
- Driver circuits
- Inverter circuits
Procurement Notes
Verify the specific ordering suffix '-13-F' indicates a 10,000-unit reel quantity per the manufacturer's ordering information table. Confirm that the 'Q' designation aligns with AEC-Q101 qualification requirements for your specific application environment. Ensure compatibility with standard SOT23 footprint dimensions during PCB layout.
Selection Notes
Select this component when an NPN digital transistor with a 4.7kΩ base resistor and 47kΩ emitter-base resistor is required. The Q suffix denotes automotive-grade qualification under AEC-Q101. Verify that the 100mA output current and 50V supply voltage meet the load requirements of the target switching application.
Part Context
This part belongs to the DDTC (R1≠R2 Series) CA family from Diodes Incorporated. It is the automotive-qualified variant of the DDTC143ZCA, distinguished by the 'Q' suffix and the '-13-F' packaging suffix indicating a 10,000-unit reel. It shares electrical characteristics with standard commercial versions but meets stricter automotive reliability standards.
