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. With its larger creepage distance, the CPC3981Z increases circuit robustness and enables cost savings.
The 800 V blocking voltage rating of the CPC3981Z makes it the ideal choice for use in industrial, energy, telecommunications, and LED lighting applications, including:
Normally ON switches.
Constant current sources.
The increased distance between the depletion mode MOSFET pins simplifies the isolation management of wide input voltage power supplies and enables compact printed circuit board layouts.
