Overview
The DDTC143ZLP-7 is an NPN pre-biased small signal transistor from Diodes Incorporated, housed in an X1-DFN1006-3 leadless surface mount package. It features a nominal input resistor (R1) of 4.7 kΩ and a nominal emitter-base resistor (R2) of 47 kΩ. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 250 mW with a thermal resistance of 500 °C/W. Operating temperature ranges from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Ultra-small leadless surface mount package suitable for automated assembly
- Totally lead-free and fully RoHS compliant
- Qualified to AEC-Q101 standards for high reliability
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging quantity and reel specifications. Confirm compliance requirements such as RoHS and halogen-free status directly with the manufacturer's latest datasheets or quality declarations before procurement.
Selection Notes
Select this component when a compact NPN digital transistor with unequal bias resistors (R1=4.7kΩ, R2=47kΩ) is required. Ensure the design accommodates the 50V voltage rating and 250mW power dissipation limits within the specified ambient temperature range using appropriate PCB copper area for thermal management.
Part Context
This part belongs to the DDTCxxxxLP series, which utilizes the X1-DFN1006-3 package. It is distinct from other DDTC variants that may use SOT packages or feature equal resistor ratios. The 'LP' designation specifically indicates the leadless DFN form factor and the R1≠R2 resistor configuration.
Replacement Considerations
Direct replacements must match the X1-DFN1006-3 package and the 4.7kΩ/47kΩ resistor ratio. Verify pinout compatibility and electrical ratings. Other parts in the DDTC143 family with different packages (e.g., SOT-23) are not direct physical substitutes without layout changes.
FAQ
What is the marking code for the DDTC143ZLP-7?
The marking code for the DDTC143ZLP-7 is N1.
What is the typical DC current gain (hFE) at IC = 10mA?
The typical DC current gain (hFE) is 150 when the collector current is 10mA and VCE is 5V.
Is the device qualified for automotive applications?
Yes, the device is qualified to AEC-Q101 standards for high reliability.
