| Discrete Semiconductor Products | 1 | Active | 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.

| Transistors | 1 | Active | 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.

| Discrete Semiconductor Products | 1 | Active | When Power MOSFETs are used in the 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 Linear 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. |
