Transistors
Rev.B
1/4
General purpose
(dual digital transistors)
EMD4 / UMD4N
Features
1) Both the DTA114Y chip and DTC144E chip in
an EMT6 or UMT6 package.
2) Mounting possible with EMT3 or UMT3 automatic
mounting machines.
3) Transistor elements are independent, eliminating
interference.
4) Mounting cost and area can be cut in half.
Structure
A PNP and NPN digital transistor
(each with a single built in resistor)
The following characteristics apply to both the DTr
1
and
DTr
2
, however, the "
-
" sign on DTr
2
values for the PNP
type have been omitted.
