UN2121/2122/2123/2124/212X/212Y
Silicon PNP epitaxial planer transistor
For digital circuits
Features
■
●
Costs can be reduced through downsizing of the equipment and
reduction of the number of parts.
●
Mini type package, allowing downsizing of the equipment and
automatic insertion through tape packing and magazine packing.
