I am planning to use the BTB10-800CW Triac for a 240Vac, 5A load. The package is TO-220. It will be used for a home appliance. My colleague always tell me that I should have at least 3mm creepage distance for the high voltage part (240Vac). I double checked the requirement of the creepage distance from the IEC and UL safety standard document, with the solder resist and CTI 600 PCB, the creepage distance is something like 1.X ~ 2mm (I forgot the exact number). However, the distance between the A1 and A2 pins on the TO-220 triac is much less than 3mm, the distance between the pads is only 0.6mm actually. I saw somebody bend the middle lead, but I think that it is unreasonable that the manufacturer make this TO-220 triac if it can not meet the safety standard. This triac has a breakdown voltage of 800V !8O
So what is the required creepage distance between the lead of the Triac?
