VDS=200V: Suitable for 48V~120V high-voltage bus systems, provides voltage spike margin, significantly reduces avalanche breakdown risk, enhances system robustness.
VGS=±20V: Wide gate drive voltage window, compatible with 10V~15V standard drive levels, can directly connect to dedicated gate drive ICs or PWM controllers.
Vth=4.21V (Typical): Higher threshold voltage, strong anti-interference capability, avoids false turn-on, suitable for industrial applications in noisy environments.
RDS(on)=17mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces conduction loss at the same current, effectively alleviates temperature rise under high current full load.
ID=80A: Ample continuous current margin, can handle short-term overloads such as motor stall and power supply surges, reducing system protection circuit design complexity.
Package TO220: Traditional through-hole package, low thermal resistance, short thermal path, easy to install heatsink, suitable for high-reliability power board layout.
