Additional Details

The FDS6990S-NL features a drain-source voltage (VDS) rating of 30V and a continuous drain current (ID) rating dependent on the specific operating conditions and thermal management. The operating and storage temperature range is typically -55°C to +150°C. It is packaged in a standard SO-8 surface mount package. The gate threshold voltage is designed to be logic-level compatible, typically around 1-3V, allowing direct drive from microcontrollers and other logic devices. This MOSFET is particularly suitable for applications requiring efficient power management in a small form factor.
