EMD2 / UMD2N / IMD2A
Transistors
General purpose
(dual digital transistors)
EMD2 / UMD2N / IMD2A
Features Dimensions (Unit : mm)
1) Both the DTA124E chip and DTC124E chip in a EMT
EMD2
or UMT or SMT package.
2) Mounting possible with EMT6 or UMT6 or SMT6 (6) (5) (4)
automatic mounting machines.
3) Transistor elements are independent, eliminating
(1) (2) (3)
interference.
4) Mounting cost and area can be cut in half.
