2SJ634-E-VB Product details
Back to previous pageProduct introduction：
2SJ634-E-VB is a Single P-MOS deeply optimized for medium power switching applications. The Trench process balances low conduction losses and high switching speed, while the TO251 package achieves a good trade-off between heat dissipation and assembly convenience. The combination of 60V withstand voltage, -20A current capacity, and 66mΩ (at 10V) on-resistance makes it a reliable choice for low-voltage negative power rails, battery protection, and load switch applications, especially suitable for industrial and consumer systems with clear requirements for voltage margin and thermal performance.
