Frequently Asked Questions
How much AC load current can the BTA41-800B switch continuously?
The BTA41-800B is rated for 40A RMS on-state current and can block up to 800V, making it suitable for switching high-power AC loads such as motors and heaters in industrial control panels.
Why is the isolated TOP3 package useful when mounting this triac to a heat sink?
Because the case connection is electrically isolated, the BTA41-800B in its TOP3 plastic package can be mounted directly to a shared heat sink alongside other components without additional insulating hardware, while handling an 80mA maximum holding current.
What gate drive signal is required to trigger the BTA41-800B into conduction?
Triggering requires a DC gate current of up to 100mA at a maximum gate voltage of 1.5V, and the device maintains immunity to false triggering with a minimum critical rate of rise of off-state voltage of 250 V/us.
