EMD2 / UMD2N / IMD2A
Transistors
General purpose
(dual digital transistors)
EMD2 / UMD2N / IMD2A
Features
1) Both the DTA124E chip and DTC124E chip in a EMT
or UMT or SMT package.
2) Mounting possible with EMT6 or UMT6 or SMT6
automatic mounting machines.
3) Transistor elements are independent, eliminating
interference.
4) Mounting cost and area can be cut in half.
