| Transistors | 1 | Active | The new 200V X4 Ultra Junction MOSFETs are designed with the latest Ultra Junction technology for high efficiency power applications. They are available in TO-247 and TO-268HV Packages. They offer lower RDS(on) simultaneously with reduced gate and output charges, which allows for more efficient switching at given frequency. |
| FETs, MOSFETs | 1 | Active | 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. |
| Single FETs, MOSFETs | 3 | 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. |
| Discrete Semiconductor Products | 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. 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 |

| Single FETs, MOSFETs | 1 | Active | 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.
