EMB9 / UMB9N / IMB9A

Transistors

1/2

General purpose

(dual digital transistors)

EMB9 / UMB9N / IMB9A

Features

1) Two DTA144Ys 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.

4) Mounting cost and area can be cut in half.
