The Si7882DP, Si7940DP, and Si7540DP PowerPAK power MOSFETs from Siliconix Inc. come in standard SO-8 packages measuring 6.15-by-5.15-by-10.7mm and are intended for point-of-load (POL) dc/dc conversion applications in fixed telecom systems.

As POL devices, the Siliconix MOSFETs are designed for use in low-voltage step-down applications in 5V and 3.3V distributed bus architectures. The single n-channel Si7882DP and dual n-channel Si7940DP devices have a drain-source and gate-source voltage rating of 12V and 8V, respectively, while the Si7540DP n- and p-channel device is rated at 112V and 18V.

The MOSFETs are claimed to offer industry-low on-resistance values, as well as low on-resistance times gate charge products, resulting to lower switching and conduction losses, and thus higher-efficiency dc/dc circuits.
