Additional Details

The SI7461DP is typically packaged in an SO-8 package. Key electrical specifications include a drain-source voltage (VDS) of 30V, a continuous drain current (ID) of approximately 11A depending on the test conditions, and a gate-source voltage (VGS) of ±20V. The low on-resistance (RDS(on)) value, often less than 6.5 mΩ at VGS = 10V, ensures minimal power dissipation during operation. The device is also designed to minimize gate charge (Qg), which further enhances its switching performance. Its combination of low on-resistance, fast switching speed, and small package makes it well-suited for modern power electronics applications.

The Vishay SI7461DP N-Channel MOSFET provides an efficient and reliable solution for a variety of power management applications. Its features and benefits make it a preferred choice for designers seeking to optimize power efficiency and performance in their electronic systems.
