I am reading the datasheet of TRIAC (T1235T-8G). I am not sure how to trigger the
TRIAC and what do they mean by
maximum Vgt voltage (Page 2, Table 3).
Basically, I want to use that TRIAC for
crowbar protection and I want to select a mechanism to trigger the TRIAC.
Note: Ignore the LM431 in the picture as I would be using some other reference IC.
Picture taken from here.
I want to use the TRIAC in Quadrant 1 (because of it's sensitivity). I have few queries:
- Does TRAIC for Quadrant 1 will be triggered for any positive gate voltage (but gate should have minimum Gate current of 1.75mA)? So, how can I calculate minimum gate voltage required to latch the TRIAC?
- What do they mean by Maximum Gate Trigger Voltage? Does it mean if I apply more voltage than the maximum, then TRIAC may get damage?
