Key Technical Specifications

• Drain-Source Voltage :500V
• Continuous Drain Current :13A (varies slightly by manufacturer, e.g., 12.5A for some variants)
• On-Resistance :48 Ω
• Gate-Source Voltage :± 30V
• Total Gate Charge :43nC (typical)
• Power Dissipation :Up to 168W (depending on the package)
