STW46NF30:N-channel 300 V, 0.063 Ohm typ., 42 A STripFET(TM) II Power MOSFET in a TO-247 package

These Power MOSFETs have been developed using STMicroelectronics’ unique STripFET process, which is specifically designed to minimize input capacitance and gate charge. This renders the devices suitable for use as primary switch in advanced high-efficiency isolated DC-DC converters for telecom and computer applications, and applications with low gate charge driving requirements.

Key Features

  • Exceptional dv/dt capability
  • 100% avalanche tested
  • Low gate charge
