BTA41-800B datasheet by STMicroelectronics

BTA41-800B Frequently Asked Questions (FAQs)

• What is the maximum surge current that the BTA41-800B can handle?
  The BTA41-800B 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 5V. Additionally, the gate signal should have a rise time of less than 1μs.
• What is the recommended heatsink for the BTA41-800B?
  The recommended heatsink for the BTA41-800B 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 BTA41-800B in a DC circuit?
  No, the BTA41-800B is designed for AC circuits only. Using it in a DC circuit can lead to latch-up and damage to the device.
• How do I protect the BTA41-800B from overvoltage?
  To protect the BTA41-800B from overvoltage, a voltage clamp or a varistor can be used to limit the voltage across the device. Additionally, a fuse or a circuit breaker can be used to disconnect the power supply in case of an overvoltage condition.
