Transistors
2SA1738
Silicon PNP epitaxial planar type
For high speed switching
■ Features
• High speed switching (Pair with 2SC3757)
• Low collector-emitter saturation voltage VCE(sat)
• Mini type package, allowing downsizing of the equipment and au-
tomatic insertion through the tape packing and the magazine
packing.
■ Absolute Maximum Ratings Ta = 25°C
