MOSFETs Raise Protection Levels For Inductive Loads

Additions to the IntelliFET range of self-protected MOSFETs include the 60V, 75-mΩ single N-channel ZXMS6006DG/SG and dual N-channel ZXMS6006DT8. Both provide thermal shutdown, short circuit, over voltage, over current, and input ESD protection. The dual-channel ZXMS6006DT8 integrates over-temperature, over-current, over-voltage and input ESD protection on each of its two independent and isolated switching channels.  Packaged in a SM8, it delivers a thermal efficiency 30% better than comparable SO8 devices. The single-channel ZXMS6006DG (drain connected to tab) and ZXMS6006SG (drain connected to source) come in SOT223 packages. Both specify nominal load current ratings of 2.8A at an input voltage of 5V, and have an avalanche clamping rating of 490 mJ. Depending on the device, prices range from $0.34 to $0.50 each/10,000.
