TK33S10N1Z,LXHQ-VB Product details
Back to previous pageProduct introduction：
TK33S10N1Z,LXHQ-VB is a Single N-MOS deeply optimized for medium-power switching scenarios. The Trench process balances low switching loss and high reliability, while the TO252 package achieves an ideal balance between heat dissipation capability and soldering processability. The combination of 100V withstand voltage, 85A current carrying capacity, and 8.5mΩ on-resistance makes it a preferred alternative to traditional DPAK or D2PAK packaged devices, especially suitable for industrial and automotive applications with high requirements for power density and thermal performance.

VDS=100V: Suitable for 24V/48V/60V systems, providing ample spike voltage margin, reducing avalanche breakdown risk, and enhancing system robustness.
VGS=±20V: Compatible with 4.5V~12V drive levels, can directly connect to MCU/PMIC or dedicated gate driver ICs, simplifying peripheral circuit design.
Vth=2.5V (Typical): Moderate threshold voltage, balancing noise immunity and low-voltage drive feasibility, adaptable to various drive scenarios.
RDS(on)=8.5mΩ @ VGS=10V; 10.5mΩ @ VGS=4.5V: Ultra-low on-resistance maintained under both drive levels, significantly reducing full-load temperature rise, allowing for smaller heatsinks or copper area.
ID=85A: Ample continuous current margin to handle high current surge scenarios like motor startup and power hot-swap.
Package TO252: Compatible with mainstream PCB layouts, low thermal resistance and parasitic inductance, supports higher frequency switching, and facilitates automated assembly.
