Littelfuse/Commercial Vehicle Products

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

Tailored specifically for applications requiring Power MOSFETs to operate in their current saturation regions, these unique devices feature low thermal resistances, high power density, and extended Forward Bias Safe Operating Areas (FBSOA). When Power MOSFETs are utilized in linear-mode operation, as opposed to their conventional switch-mode one, they are required to endure substantially high thermal and electrical stresses due to the simultaneous occurrence of high drain voltages and currents; these extreme stresses can cause typical devices to fail. Littelfuse LinearL2™ Power MOSFETs have been designed to address these kinds of device failures – the FBSOAs are "extended" when the positive feedback of electro-thermal instability is suppressed, giving rise to larger "operating windows." The FBSOAs are guaranteed at 75°C.

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

The High Voltage series of N-Channel Standard MOSFETs are suitable for a wide variety of power switching systems, including high-voltage power supplies, capacitor discharge circuits, pulse circuits, and current regulators. Advantages: Easy to mount Space savings High power density

Trench P-Channel MOSFETs are well suited for ‘high side’ switching applications where a simple drive circuit referenced to ground can be employed, avoiding additional ‘high side’ driver circuitry commonly involved when using an N-Channel MOSFET. This enables designers to reduce component count, thereby improving drive circuit simplicity and over-all component cost structure. Furthermore, it allows for the design of a complementary power output stage with a corresponding N-Channel MOSFET, for a power half bridge stage paired with a simple drive circuit.
