AP4439GH-VB Product details
Back to previous pageProduct introduction：
** AP4439GH-VB is a Single P-MOS optimized for low-voltage power switch applications. Its Trench technology balances low switching losses and high reliability, while the TO252 package achieves a good balance between heat dissipation capability and assembly convenience. The combination of 30V withstand voltage, 60A current carrying capacity, and 11mΩ on-resistance makes it an ideal upgrade option to replace traditional DPAK or SOP-8 packaged devices, especially suitable for high power density, high current applications.**
