PSMN035-150B,118-VB Product details
Back to previous pageProduct introduction：
PSMN035-150B,118-VB is a Single N-MOS optimized for high-voltage power switching scenarios. The Trench process balances low conduction loss with high switching reliability. The TO263 package strikes a good balance between heat dissipation and soldering process. The combination of 150V withstand voltage, 45A current carrying capacity, and 35mΩ on-resistance makes it a preferred alternative to traditional TO220 packaged devices in communication power supplies, industrial control, and automotive systems, especially suitable for applications with high thermal dissipation and power density requirements.
