FAQ
The GDM50N60L features low gate charge and fast switching characteristics that minimize switching losses at high frequencies. Its low output capacitance and optimized internal design enable efficient operation in applications switching above 100kHz. The module's low RDS(on) also contributes to reduced conduction losses.
We recommend using a dedicated gate driver IC with +10V/-5V drive capability. The gate resistance should be between 1Ω and 5Ω for optimal switching performance. Include TVS diodes for ESD protection on the gate-source path. Proper PCB layout is crucial to minimize parasitic inductance in the gate drive loop.
The module should be mounted on an adequate heatsink with thermal resistance below 2.0°C/W for reliable operation. For high-duty-cycle applications, consider forced air cooling. The junction-to-case thermal resistance is 1.0°C/W, allowing for effective heat dissipation with proper thermal design.
