SI4412ADY-T1-E3-VB Product details
Back to previous pageProduct introduction：
The SI4412ADY-T1-E3-VB is a Single N-MOS deeply optimized for low-voltage power switching applications. Using Trench technology, it balances low conduction losses with high switching reliability. The SOP8 package strikes a good balance between heat dissipation capability and board space, making it suitable for high-density power modules and industrial control applications. The combination of 30V voltage rating, 13A current carrying capability, and 8mΩ on-resistance makes it an ideal upgrade option to replace traditional DPAK or similar SOP-8 devices, especially for systems with strict efficiency and temperature rise requirements.
