The BTA201-800E can handle surge currents up to 10A for 10ms, but it's recommended to limit the surge current to 5A for 10ms to ensure reliable operation.
To ensure the thyristor is fully turned off, the gate current should be reduced to zero and the gate voltage should be kept at a negative voltage (typically -10V to -15V) for a sufficient time (typically 10us to 20us) during the commutation phase.
The recommended gate resistor value for the BTA201-800E is between 10Ω to 100Ω, depending on the specific application and gate drive circuitry. A higher gate resistor value can help reduce EMI, but may also increase the turn-on time.
Yes, the BTA201-800E can be used in a phase control circuit, but it's essential to ensure that the thyristor is fully turned off during the commutation phase to prevent unwanted conduction. A suitable snubber circuit may also be required to reduce voltage transients.
The maximum junction temperature that the BTA201-800E can withstand is 150°C. However, it's recommended to keep the junction temperature below 125°C for reliable operation and to ensure a long lifespan.
