PolarP IXTY2P50PA P-Channel MOSFET
IXTY2P50PA, the first automotive-grade PolarP P-Channel Power MOSFET. This innovative product design meets the demanding requirements of automotive applications, providing exceptional performance and reliability.
800 volt, N-channel depletion mode MOSFET
Littelfuse, Inc., an industrial technology manufacturing company, is pleased to announce the launch of CPC3981Z, an 800 V, 100 mA, 45 Ohm, small power N-Channel depletion mode MOSFET. Compared to a standard SOT-223 package, this new product's SOT-223-2L package features a removed middle pin. That increases the drain-gate pin spacing from 1.386 millimeters to more than four millimeters. The extended creepage distance is beneficial in higher voltage applications such as switch mode power supplies or power factor correction startup circuits because designers can avoid the need for costly conformal coating or potting. The key differentiator of the CPC3981Z is its modified SOT-223-2L package which enables designers to meet the required extended creepage distance for higher voltage applications with a small discrete device.
656 and 658 series fuse blocks
Littelfuse, Inc announced the latest release of the 656 and 658 Series Fuse Blocks product line. These fuse blocks offer a higher amperage rating, giving electronics engineers and designers more options depending on their specific application requirements. The key differentiator of these high-resistance fuse blocks is their ability to support a higher amperage rating available in PCB-mounted (656) and surface-mounted (658) options. While the current versions are rated up to 16 A, Littelfuse is now offering versions rated at 20 A and 30 A.
