Transistors
EMB3 / UMB3N / IMB3A
General purpose (dual digital transistors)
EMB3 / UMB3N / IMB3A
!Features
1) Two DTA143T chips 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.
