STP20NM50 Frequently Asked Questions (FAQ)

  • The maximum operating frequency of the STP20NM50 is 20 kHz, but it can be operated at higher frequencies with reduced power handling capability.

  • To ensure proper biasing, the gate-source voltage (Vgs) should be between 2V and 4V, and the drain-source voltage (Vds) should be between 10V and 50V, depending on the application.

  • The maximum power dissipation of the STP20NM50 is 125W, but this can be increased with proper heat sinking and thermal management.

  • Yes, the STP20NM50 is suitable for high-reliability applications, such as aerospace, automotive, and industrial control systems, due to its robust design and manufacturing process.

  • To protect the STP20NM50 from ESD, handle the device with anti-static wrist straps, mats, or bags, and ensure that the device is stored in a conductive bag or tube when not in use.
