AM4543C-T1-PF-VB Product details
Back to previous pageProduct introduction：
The AM4543C-T1-PF-VB is a Dual N+P Complementary MOSFET deeply optimized for medium and low voltage power switching scenarios. The Trench technology balances low switching losses and high reliability. The SOP8 package achieves an ideal balance between thermal performance and board area. The combination of 60V voltage rating, N/P dual-channel 5.3A/-4.9A current capability, and 26/55mΩ on-resistance makes it a preferred device for applications such as half-bridge drives, synchronous rectification, and battery protection, especially suitable for high-density designs requiring simultaneous driving of high-side and low-side switches.
