TK5A65DA(STA4,Q,M)-VB Product details
Back to previous pageProduct introduction：
TK5A65DA(STA4,Q,M)-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios. The Planar planar process balances robust avalanche endurance with low leakage current, and the TO220F full-plastic package strikes a balance between heat dissipation performance and insulation safety. The combination of 650V withstand voltage, 4A current capacity, and 2.56Ω on-resistance makes it a reliable choice for high-voltage applications such as switching power supplies, industrial control, and home appliance frequency conversion, especially suitable for projects with strict requirements for voltage margin and system stability.
