Product introduction：
TK165E65Z5,S1X-VB is a Single N-MOS deeply optimized for high-voltage power switching scenarios, using SJ_Multi-EPI super junction process to balance low conduction loss and high switching speed. The TO220 package balances high current heat dissipation with system assembly convenience. The combination of 650V withstand voltage, 20A current carrying capacity, and 160mΩ on-resistance makes it an ideal power switch option for high-voltage, high-reliability applications, particularly suitable for scenarios such as industrial power supplies, photovoltaic inverters, and motor drives with strict requirements for voltage tolerance and loss.

VDS=650V: Suitable for 380V/220V industrial systems and high-voltage DC buses, providing ample spike voltage margin and significantly reducing avalanche breakdown risk.
VGS=±30V: Wide gate drive margin, compatible with various gate driver ICs and level-shifting circuits, enhancing system noise immunity.
Vth=3.5V (Typical): Moderate threshold voltage effectively resisting dv/dt-induced false turn-on, enhancing high-voltage switching reliability.
RDS(on)=160mΩ @ VGS=10V: Low on-resistance from superjunction technology, minimizing full-load loss, simplifying thermal design and improving overall system efficiency.
ID=20A: Ample continuous current capability covering steady-state and peak demands of most medium-power high-voltage loads.
Package TO220: Mature through-hole package with short thermal path and low thermal resistance, easy to mount on heatsink, suitable for higher power application scenarios.
Domain and module applications：
Industrial Switching Power Supplies: Low on-resistance and high voltage withstand capability match flyback/forward topologies, effectively reducing primary side losses and improving power conversion efficiency.
Photovoltaic Inverters: Superjunction structure reduces switching losses, 20A current capability meets the power stage requirements of string inverters, improving power generation revenue.
Motor Drives/Variable Frequency Drives: Direct drive from high-voltage bus, large voltage margin, excellent PWM switching characteristics, improving motor operation smoothness and reducing controller temperature rise.
UPS Uninterruptible Power Supplies: 650V voltage tolerance handles bus fluctuations, low RDS(on) reduces conduction losses, extending backup time and improving system reliability.
High-Voltage DC-DC Converters: Used as a switching transistor in PFC and LLC circuits, superjunction technology enables high-frequency design, reducing magnetic component size.
Charging Station Auxiliary Power Supplies: Adapts to wide input voltage range, wide operating temperature capability enhances long-term stability in harsh outdoor environments. Selection Summary: TK165E65Z5,S1X-VB achieves an excellent balance between high voltage tolerance, current capability, on-resistance, and package thermal performance.
