Diodes Incorporated Announces World’s Smallest Self-Protected MOSFET


Diodes Inc. / Zetex

Adding to its IntelliFETTM product range, Diodes Incorporated has introduced the world’s smallest fully self protected low side MOSFET. Packaged in the 2.3mm x 2.8mm footprint ‘flat’ SOT23F package, the ZXMS6004FF takes 85% less board space than incumbent 7.3mm x 6.7mm footprint SOT223 packaged parts.

Despite its miniature format, the SOT23 flat package has superior thermal performance that enables the ZXMS6004FF to deliver a package power density three times that of its much larger packaged counterpart. Additionally, with an on-state resistance of just 500mO, this latest IntelliFETTM also ensures that power dissipation is kept to an absolute minimum.

Integrating ESD, over voltage, over current and over temperature protection into a single thermally efficient package, the ZXMS6004FF protects both itself and the load and will help to reduce component count, pcb size and overall system cost in a range of automotive and industrial applications. The device’s ultra small form factor will also enable space-restricted applications to integrate self-protected MOSFETs for the very first time.

The device has a continuous current rating of 1A and is qualified to the AECQ101 standard, being tolerant of 60V load dump transients. With a logic level input of either 3.3V or 5V, the ZXMS6004FF can be driven directly from microcontroller outputs.
