ZXTC6720MCTA

Overview

The ZXTC6720MCTA is a dual transistor combination in an 8-pin DFN3020B-8 package, integrating an NPN and a PNP die. The NPN transistor supports a continuous collector current of 3.5A with a collector-emitter breakdown voltage exceeding 80V and a maximum saturation voltage of 185mV at 1A. The PNP transistor handles -2.5A continuously with a breakdown voltage greater than -70V and a saturation voltage of -220mV at -1A. The device features a low profile height of 0.8mm and operates within a temperature range of -55°C to +150°C.

Procurement Notes

Verify the specific ordering suffix MCTA corresponds to the required reel size and tape width specifications. Confirm that the DE4 product marking code matches the intended assembly identification requirements. Ensure compliance with RoHS and halogen-free material declarations as specified in the manufacturer's green policy documentation prior to final procurement authorization.

Selection Notes

Select this component when space constraints require a footprint smaller than standard SOT26 packages while maintaining high current handling capabilities. Evaluate the thermal resistance characteristics against the specific PCB copper area and layer configuration to ensure adequate heat dissipation. Consider the transition frequency and switching times for high-speed application requirements compared to discrete alternatives.

Part Context

This part belongs to the ZXTC6720MC family of dual low saturation transistor combinations manufactured by Diodes Incorporated. It utilizes a molded plastic case with pre-plated NiPdAu leadframes and meets UL 94V-0 flammability ratings. The device is designed for surface mount technology applications requiring robust performance in compact form factors.

Replacement Considerations

Direct substitutes must match the DFN3020B-8 package dimensions and electrical characteristics. Verify equivalent saturation voltages and current ratings for both NPN and PNP sections. Ensure thermal resistance values are compatible with the existing board layout to maintain safe operating temperatures.
