Overview
The ZXTC6718MCTA is a complementary pair of low saturation transistors in an 8-pin W-DFN3020-8 Type B package. The NPN transistor provides a continuous collector current of 4.5A with a maximum saturation voltage of 150mV at 1A and an equivalent on-resistance of 47mΩ. The PNP transistor supports -3.5A continuous collector current, featuring a maximum saturation voltage of -220mV at -1A and an equivalent on-resistance of 64mΩ. Both devices operate within a junction temperature range of -55°C to +150°C and are qualified to AEC-Q101 standards.

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details. The 'CTA' suffix indicates a tape and reel quantity of 3,000 units on a DB2 7-inch reel with 8mm tape width. Confirm RoHS compliance and halogen-free status requirements match the project specifications before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a footprint significantly smaller than standard SOT26 or TSOP6 packages while maintaining high current handling capabilities. The device is suitable for applications requiring efficient thermal dissipation through exposed pad mounting. Ensure the PCB layout accommodates the 3020-8 Type B dimensions and utilizes sufficient copper area to maximize the thermal performance benefits inherent to the W-DFN package design.
Part Context
This part belongs to the ZXTC6718MC family of complementary low saturation transistors manufactured by Diodes Incorporated. It is designed as a compact solution for power switching applications where board real estate is limited. The family includes variants such as the ZXTC6718MCQTA, which shares identical electrical characteristics but is specifically designated for automotive qualification under AEC-Q101 standards.
Replacement Considerations
Direct substitutes include other complementary transistor pairs housed in W-DFN3020-8 packages with comparable current ratings and saturation voltages. Verify pinout compatibility and thermal resistance values when replacing with components from different manufacturers to ensure circuit stability.
