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.
