2SK3492-TL-E-VB Product details
Back to previous pageProduct introduction：
2SK3492-TL-E-VB is a Single N-MOS optimized for low-voltage power switching scenarios. The Trench process balances low switching loss and high reliability, while the TO252 package achieves a good trade-off between heat dissipation capability and soldering process compatibility. With a 60V withstand voltage, 18A current capacity, and 73mΩ on-resistance, it serves as an ideal upgrade option to replace traditional DPAK or SOT-223 packaged devices, especially suitable for batch applications requiring medium-to-high power density and good heat dissipation.
