hello!
i am looking to do a project using triacs to control a JBC soldering iron. i am new to using triacs, having never done a project with them. i'm basing my design (picture below) on an existing schematic, which uses a BTB26-600 triac. LINK: https://www.digikey.com/products/en?keywords=BTB26-600. however, the vast majority of the components i'm using are SMD in nature, and the maximum current of this triac is 25A, but the supply for this project has a maximum current of 7.5A @24vac, so its much bigger than i need. also using a smd package would make fitting it to an enclosure easyer.
my question is: could i replace the afformentioned triac with a T2535-800G? LINK: https://www.digikey.com/product-detail/en/stmicroelectronics/T2535-800G-TR/497-10581-1-ND/2294945. this one is still rated for 25A (i only need ~8A, but a little overkill never hurt), and is snubberless. are there any differences between the two that i'm overlooking, or could i just drop it in as a direct replacement? am i overlooking something obvious?
from my reasearch on the difference between the two, it said that the snubberless one didn't "need" a snubber circuit as it is a differently designed triac. is this correct?
the PD nets go to a atmega328p microcontroller, and the T+/- nets go to a mx6675 thermocouple IC. if anyone wants to see my full schematic, i can post it.
any help/ recommendations are appreciated. thanks!
