The following characteristics apply to both the DTr1 and DTr2, however, the “–” sign on DTr2 values for the PNP type have been omitted.

• Features
1) Includes a DTA124E and a DTC124E transistor in a single UMT and a SMT package.
2) Ideal for power switch circuits.
3) Mounting cost and area can be cut in half.

• Structure
A PNP and a NPN digital transistor (each with two built in resistors)
