EMB2 / UMB2N / IMB2A
Transistors
General purpose
(dual digital transistors)
EMB2 / UMB2N / IMB2A
Features
1) Two DTA144E chips in a EMT or UMT or SMT
package.
2) Same size as EMT3 or UMT3 or SMT3 package, so
same mounting machine can be used for both.
3) Transistor elements are independent, eliminating
interference.
Structure
Epitaxial planar type
PNP silicon transistor (Built-in resistor type)
The following characteristics apply to both DTr
1
and
DTr
2
.
