The TMMDB3TG from STMicroelectronics is a Diac that is ideal for heating, lighting, home appliances, over-voltage crowbar protection, inrush current limiting circuits, motor control circuits, and general-purpose AC line load switching applications. It has a break-over voltage of 32 V and a break-over current of less than 15 µA. This Diac functions as a triggering diode with a fixed voltage reference and can also be used in conjunction with triacs to enable simplification of gate control circuits or as a starting element in fluorescent lamp ballasts. It is available in a surface-mount package that measures 3.30 x 1.59 mm.
