MCU2D5N03L-TP-VB Product details
Back to previous pageProduct introduction：
The MCU2D5N03L-TP-VB is a Single N-MOS deeply optimized for low-voltage, high-current power switching scenarios. The Trench process balances ultra-low on-resistance with high switching speed, and the TO252 package achieves an ideal balance between heat dissipation capability and soldering process compatibility. The combination of 30V withstand voltage, 120A current carrying capacity, and 2mΩ-level on-resistance makes it a cost-effective core device for high-power-density power supplies, power tools, and automotive electronics, especially suitable for compact designs requiring high current throughput and low loss performance.
