EMD3 / UMD3N / IMD3A
Transistors
General purpose
(Dual digital transistors)
EMD3 / UMD3N / IMD3A
Features
1) Both the DTA114E chip and DTC114E chip in a EMT
or UMT or SMT package.
2) Mounting possible with EMT3 or UMT3 or SMT3
automatic mounting machines.
3) Transistor elements are independent, eliminating
interference.
4) Mounting cost and area can be cut in half.
