Overview
The ZXTD618MCTA is a dual NPN low saturation switching transistor manufactured by Diodes Incorporated. It operates with a collector-emitter voltage of 20V and supports a continuous collector current of 4.5A. The device features a low saturation voltage of 150mV at 1A and an equivalent on-resistance of 47mΩ. Packaged in a DFN-3020B-8 (DFN3020B-3) surface-mount case, it has a nominal height of 0.8mm and a thermal resistance to ambient of 83.3°C/W under standard conditions. The transition frequency is 140MHz, and the operating temperature range spans from -55°C to +150°C.
Feature Summary
- Dual NPN configuration reduces footprint and component count
- Low saturation voltage for efficient power switching
- High current gain specified up to 6A
- Qualified to AEC-Q101 standards for automotive reliability
Applications
- DC-DC Converters
- Charging circuits
- Motor control
- Power switches
- Portable applications
Procurement Notes
Verify the specific ordering suffix MCTA against official documentation to confirm reel size, tape width, and quantity per reel specifications. Ensure compliance with RoHS and halogen-free requirements as stated in the manufacturer's green policy. Confirm moisture sensitivity level and storage conditions prior to assembly.
Selection Notes
Select this component for applications requiring high current handling within a compact surface-mount package. The low saturation voltage minimizes power loss during conduction. Evaluate thermal performance based on PCB copper coverage and airflow conditions, as thermal resistance varies significantly with mounting parameters.
Part Context
This part belongs to the ZXTD618 series of dual transistors designed for space-constrained designs. It utilizes a DFN3020B-3 package that offers a 50% smaller footprint compared to TSOP6 and SOT26 packages while maintaining efficient thermal dissipation characteristics suitable for portable electronics.
Replacement Considerations
Consult official substitution lists for verified equivalents. Cross-referencing requires matching dual NPN configuration, 20V VCEO rating, 4.5A IC capability, and DFN3020B-8 package dimensions.
