EMD3 / UMD3N / IMD3A
Transistors
General purpose
(Dual digital transistors)
EMD3 / UMD3N / IMD3A
Features
1) Both the DTA114E chip and DTC114E chip 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.

Products listed in this document are no antiradiation design.
The products listed in this document are designed to be used with ordinary electronic equipment or devices
(such as audio visual equipment, office-automation equipment, communications devices, electrical
appliances and electronic toys).
Should you intend to use these products with equipment or devices which require an extremely high level
of reliability and the malfunction of which would directly endanger human life (such as medical
instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers
and other safety devices), please be sure to consult with our sales representative in advance.
It is our top priority to supply products with the utmost quality and reliability. However, there is always a chance
of failure due to unexpected factors. Therefore, please take into account the derating characteristics and allow
for sufficient safety features, such as extra margin, anti-flammability, and fail-safe measures when designing in
order to prevent possible accidents that may result in bodily harm or fire caused by component failure. ROHM
cannot be held responsible for any damages arising from the use of the products under conditions out of the
range of the specifications or due to non-compliance with the NOTES specified in this catalog.
