Technical Specifications:

The SPB70N10L E3045A features a drain-source voltage (VDS) of 100V, a continuous drain current (ID) of 70A, and a pulsed drain current (IDpulse) of 280A. The on-resistance (RDS(on)) is typically 11 mΩ at VGS = 10V. The gate charge (Qg) is typically 35 nC. It is available in a PG-TO263-3 package.

The low on-resistance minimizes conduction losses, while the fast switching speed minimizes switching losses, contributing to overall efficiency. The logic level gate drive enables direct control by microcontrollers, simplifying the design and reducing the need for external gate drive circuitry. The avalanche rating enhances the device's robustness and reliability, making it suitable for demanding applications.
