2SJ687-ZK-E2-AY-VB Product details
Back to previous pageProduct introduction：
2SJ687-ZK-E2-AY-VB is a Single P-MOS deeply optimized for low-voltage, high-power switching scenarios. The Trench process balances low switching losses with high reliability, and the TO252 package strikes a balance between heat dissipation capability and board area. The combination of 30V withstand voltage, 100A current carrying capacity, and 5mΩ on-resistance makes it an ideal high-cost-performance alternative to traditional DPAK or SOP-8 packaged devices, especially suitable for high-current, high-density power systems.
