STMicroelectronics provides a recommended PCB layout in their application note AN4392, which includes guidelines for thermal pad connection, copper thickness, and spacing to ensure optimal thermal performance.
The selection of a heatsink for the BTA20-600CW depends on the application's thermal requirements. STMicroelectronics provides a thermal resistance calculator tool that helps engineers select the correct heatsink based on the device's power dissipation, ambient temperature, and desired junction temperature.
According to STMicroelectronics, the maximum allowed voltage imbalance between the two thyristor legs of the BTA20-600CW is 10% of the maximum repetitive peak voltage (VDRM). Exceeding this limit may lead to uneven current sharing and reduced device reliability.
Yes, the BTA20-600CW is designed to withstand high dv/dt rates. However, it's essential to ensure that the device is properly snubbed to prevent voltage spikes and oscillations. STMicroelectronics recommends using a suitable snubber circuit to limit the dv/dt to 500 V/μs or less.
STMicroelectronics recommends using a gate drive circuit with a low impedance output stage and a high current capability to ensure fast and reliable thyristor triggering. A recommended gate drive circuit is provided in the application note AN4392.
