BTA26-800BW datasheet by STMicroelectronics

BTA26-800BW Frequently Asked Questions (FAQs)

• What is the maximum surge current that the BTA26-800BW can handle?
  The BTA26-800BW can handle surge currents up to 100A for 10ms, but it's recommended to derate the current to ensure reliable operation.
• How do I ensure the thyristor is properly triggered?
  To ensure proper triggering, the gate current should be at least 100mA and the gate voltage should be between 2.5V and 10V. Additionally, the gate signal should have a rise time of less than 1μs.
• What is the recommended heatsink for the BTA26-800BW?
  The recommended heatsink for the BTA26-800BW is a heatsink with a thermal resistance of less than 1°C/W. The heatsink should also be designed to handle the maximum power dissipation of the thyristor.
• Can I use the BTA26-800BW in a DC circuit?
  No, the BTA26-800BW is designed for AC circuits only. Using it in a DC circuit can lead to unreliable operation and reduced lifespan.
• How do I protect the BTA26-800BW from overvoltage?
  To protect the BTA26-800BW from overvoltage, a voltage clamp or a varistor can be used to limit the voltage across the thyristor to its maximum rated value.
