UMB3N_1 Datasheet, PDF (1/3 Pages) Rohm – General purpose (dual digital transistors)

Transistors
EMB3 / UMB3N / IMB3A
General purpose (dual digital transistors)
EMB3 / UMB3N / IMB3A
zFeatures
1) Two DTA143T chips in a EMT6 or UMT6 or SMT6
package.
2) Mounting possible with EMT3 or UMT3 or SMT3
automatic mounting machines.
3) Transistor elements are independent, eliminating
interference.
zStructure
Dual PNP digital transistor
(each with single built in resistor)
The following characteristics apply to both DTr1 and DTr2.
