• Robust performance in high-voltage and high-current applications
• Reduced switching losses at high frequencies
• Simplified drive circuitry
• Increased system reliability

Additional Details:

The BUZ70 features a drain-source voltage (VDS) rating of 200V, a continuous drain current (ID) rating of 9.5A, and a pulsed drain current (IDM) rating of 38A. It has a typical on-state resistance (RDS(on)) of 0.4 Ohms. The device is available in a TO-220 package, which offers good thermal dissipation. The BUZ70's design allows for efficient power conversion and robust operation in various electronic systems. As this component is end-of-life, careful consideration should be given to the datasheet specifications when selecting a suitable replacement. Key parameters to consider include VDS, ID, RDS(on), gate charge, and thermal resistance.
