TMMDB3 is a 3A DIAC MINIMELF with a rated working voltage of 32V and a working temperature range of -40℃ to 125℃.
The TMMDB3 is a 3A DIAC designed for use as a trigger diode with a fixed voltage reference. It can be used in conjunction with triacs for simplified gate control circuits or as a starting element in fluorescent lamp ballasts. The device features a breakover voltage range of 28 to 36V and is packaged in the MINIMELF format.
The document provides absolute maximum ratings, including a storage temperature range of -40 to +125°C. It details electrical characteristics such as repetitive peak on-state current, breakover voltage symmetry, and rise time. Mechanical data and package dimensions are also included.
