  Features                                                                      Dimensions (Unit : mm)
1) Both the DTA114E chip and DTC114E chip in a EMT                               EMD3
   or UMT or SMT package.
2) Mounting possible with EMT3 or UMT3 or SMT3                                                   (6) (5) (4)
   automatic mounting machines.
3) Transistor elements are independent, eliminating
   interference.                                                                                 (1) (2) (3)

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