The BUZ346 is an N-channel Power MOSFET originally manufactured by Siemens, now Infineon Technologies. It is designed for use in a wide range of power switching applications, providing efficient and reliable performance.

Applications:

• Switch-mode power supplies (SMPS)
• DC-DC converters
• Motor control
• Lighting ballasts
• Inverters

Features:

• N-Channel enhancement mode MOSFET
• High blocking voltage capability
• Fast switching speeds
• Low on-resistance (RDS(on))
• Avalanche ruggedness

Benefits:

• High efficiency due to minimized conduction losses
• Reduced switching losses for high-frequency operation
• Robust performance under transient conditions
• Simplified gate drive requirements
• Improved overall system reliability and efficiency

Additional Details:

The BUZ346 features a drain-source voltage (VDS) of 200V, a continuous drain current (ID) of 10A, and a pulsed drain current (IDM) of 40A. The typical on-state resistance (RDS(on)) is 0.22 Ohms. It is typically packaged in a TO-220 package, facilitating efficient heat dissipation. The device's characteristics make it suitable for applications demanding both high efficiency and reliable operation under various load conditions. Being an end-of-life component, potential substitutes from other manufacturers should be evaluated for new designs, considering parameters like gate charge, thermal resistance, and RDS(on) values. Always consult the datasheet for the original BUZ346 when selecting a replacement to ensure compatibility.
