SILICON TRANSISTORS
2SC2885, 2946, 2946(1)
NPN SILICON EPITAXIAL TRANSISTOR
FOR HIGH-VOLTAGE HIGH-SPEED SWITCHING
The 2SC2885, 2946, and 2946(1) are high-voltage high-speed switching power transistors featuring a small
package (MP-3) which is suitable for high-density mounting. These transistors are ideal for drivers in DC/DC
converters and switching regulators.
There are three types of transistors selectable according to the reliability requirments: 2SC2946 and 2946(1) for
industrial use, 2SC2885 for general use. The 2SC2946(1) is produced with leads so as to enable mounting directly in
a hybrid IC.
