Overview
The ZXTC6719MCTA is a complementary low saturation transistor pair in a W-DFN3020-8 package. It integrates an NPN transistor with a continuous collector current of 4A and BVCEO > 50V, alongside a PNP transistor rated for -3A and BVCEO > -40V. The NPN device features a maximum saturation voltage of 100mV at 1A and an equivalent on-resistance of 68mΩ. The PNP counterpart exhibits a max saturation voltage of -220mV at -1A with 104mΩ on-resistance. Both transistors are characterized for high current gain hold-up up to 6A. The component operates within a temperature range of -55°C to +150°C.

Procurement Notes
Verify the specific ordering suffix MCTA corresponds to the 3000-piece reel packing quantity as documented. Confirm that the W-DFN3020-8 (Type B) package dimensions align with your PCB pad layout requirements. Ensure environmental compliance needs match the halogen-free and antimony-free specifications provided in the datasheet notes.
Selection Notes
Select this component when space constraints require a smaller footprint than traditional SOT26 packages while maintaining high current switching capabilities. The low saturation voltage characteristics make it suitable for applications requiring efficient power switching with minimal heat generation. Verify thermal management strategies based on the specified junction-to-ambient resistance values for your specific board copper area.
Part Context
This part belongs to Diodes Incorporated's complementary transistor series designed for compact power switching applications. The ZXTC6719MC variant utilizes a molded plastic green compound package with pre-plated NiPdAu leadframes. It serves as a direct replacement for larger packages where board real estate is limited but high current density is required.
Replacement Considerations
Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Engineers should evaluate other complementary transistor pairs from the manufacturer's portfolio that offer similar W-DFN3020-8 packaging and comparable electrical ratings for saturation voltage and current handling.
