UMB2N Datasheet, PDF (1/2 Pages) Rohm – General purpose(dual digital transistors)

Product specification
EMB2 / UMB2N / IMB2A
zFeatures
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.
