2SK2623-TL-E-VB Product details
Back to previous pageProduct introduction：
2SK2623-TL-E-VB is a Single N-MOS carefully designed for high-voltage power switch scenarios. Using Planar technology, it balances stable withstand voltage and reliable switching characteristics. The TO252 package achieves a good balance between heat dissipation capability and assembly convenience. The combination of 650V withstand voltage, 2A current capability, and 3.4Ω (@VGS=4.5V) on-resistance makes it a cost-effective choice for applications such as home appliance power supplies, industrial auxiliary power supplies, and small high-voltage converters, especially suitable for small to medium power projects sensitive to voltage margin and system cost.
