Littelfuse/Commercial Vehicle Products

Polar™ P-Channel MOSFETS are fabricated using our Polar technology platform, which significantly reduces the on-state resistance (RDSon) by 30% and gate charge (Qg) by 40% in comparison to legacy counterparts, resulting in lower conduction loss and providing excellent switching performance. They are dynamic dv/dt and avalanche rated making them extremely rugged in demanding operating environments and can easily be paralleled due to an on-state resistance with positive temperature coefficient. These MOSFETs are ideal in a variety of applications, with best-in-class performance and competitive pricing. Applications include push-pull amplifiers, buck converters, DC choppers, power solid state relays, CMOS high power amplifiers, high current regulators, and high side switching in automotive and test equipment. The superior ruggedness of the Polar P-Channel Power MOSFETs also makes them suitable devices for motor control and power cut-off switches or power SSRs for energy saving applications. Advantages: Low gate charge results in simple drive requirement High power density Easy to parallel Fast switching

These devices are offered with drain-to-source voltage ratings from 40V to 170V and provide high current capabilities of up to 600 Amperes (Tc=@25oC). The combined high current ratings of these devices and available compact package options provide designers the ability to control more power within a smaller footprint. Furthermore, these devices promote device consolidation through the reduction or elimination of multiple paralleled lower current rated MOSFET devices in high power switching applications. The resultant effect is a reduction in part count, as well as the number of required drive components, thus improving upon over-all system simplicity, reliability, and cost. Advantages: Eliminates multiple paralleled lower current rated MOSFET devices Provides the ability to control more power within a smaller footprint Improves overall system reliability and cost

Polar™ Standard Power MOSFETs are tailored to provide designers with a device solution that offers the best compromise between performance and cost. These devices incorporate the Polar technology platform to achieve low on-state resistances (Rdson). Polar Standard MOSFETs feature low gate charge Qg values, resulting in more efficient switching at all frequencies. This gives the designer the option to operate at higher frequencies, which enables the use of smaller passive components in a variety of load switching designs. The avalanche capabilities of these devices add an additional safeguard against over-voltage transients. Advantages: Easy to mount Space savings High power density

These devices are developed using a charge compensation principle and proprietary process technology, resulting in Power MOSFETs with significantly reduced resistance RDS(on) and gate charge Qg. A low on-state resistance reduces the conduction losses; it also lowers the energy stored in the output capacitance, minimizing the switching losses. A low gate charge results in higher efficiency at light loads as well as lower gate drive requirements. In addition, these MOSFETs are avalanche rated and exhibit a superior dv/dt performance. Also due to the positive temperature coefficient of their on-state resistance, they can be operated in parallel to meet higher current requirements.

Trench Gate Power MOSFETs are ideally suited for low voltage/ high current applications, requiring an exceedingly low RDS(on), thus guaranteeing very low power Dissipation. This, combined with wide ranging operating junction temperature from -40 °C to 175 °C make them suitable candidates for automobile applications and other similar demanding applications in harsh environments.
