Datasheet EMD4 Datasheet (ROHM)

Transistors

General purpose
(dual digital transistors)

EMD4 / UMD4N

zFeatures

1) Both the DTA1 14Y 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.

zStructure

A PNP and NPN digit al transistor
(each with a single built in resistor)

The following characteristics apply to both the DTr

2, however, the “ −” sign on DTr2 values for the PNP

DTr

1 and

type have been omitted.
