ZDM4206NTA

Overview

The ZDM4206NTA is a dual N-channel enhancement mode MOSFET in an SM-8 (SOT-223) package. It features avalanche rating with a drain-source voltage of 60V and continuous drain current of 1A at 25°C. The device includes built-in body diodes for each element. Key electrical parameters include a maximum on-resistance of 1.5Ω at VGS=5V and 1Ω at VGS=10V. Input capacitance is 100pF, while reverse transfer capacitance is 20pF. Thermal resistance from junction to ambient is 55.6°C/W for a single die and 45.5°C/W when both are equally active.

Feature Summary

• Dual N-channel configuration with integrated body diodes
• Avalanche rated for repetitive energy handling
• Enhancement mode operation with low gate threshold voltage

Applications

• Low-side switching applications
• Power management circuits requiring dual channel isolation
• General purpose amplification and switching

Procurement Notes

Verify the manufacturer designation as Diodes Incorporated or Zetex Semiconductors depending on the specific production batch. Confirm the package type is SM-8 (SOT-223) and check for RoHS compliance status. Ensure the part marking matches M4206N to distinguish it from similar variants. Validate thermal performance requirements against the specified junction-to-ambient resistance values.

Selection Notes

Select this component for designs requiring two independent N-channel switches in a compact surface-mount package. Consider the 60V breakdown voltage and 1A continuous current limits for load compatibility. Evaluate thermal dissipation needs based on the 2.25W single-die power rating. Check gate drive requirements against the 1.3V to 3V threshold range for efficient switching.

Part Context

This dual MOSFET belongs to the ZDM series of small signal field-effect transistors. It is designed for general-purpose switching and amplification tasks. The SM-8 package provides a balance between thermal performance and board space efficiency. It serves as a compact solution for applications needing multiple channels without increasing footprint significantly.

Replacement Considerations

Check for direct pin-compatible substitutes within the same SM-8 package family. Verify that any replacement maintains the 60V VDS rating and similar RDS(on) characteristics. Ensure the alternative device supports the required avalanche energy specifications if used in inductive loads.
