SILICON TRANSISTORS
2SC4942
NPN SILICON TRIPLE DIFFUSED TRANSISTOR
FOR HIGH-SPEED HIGH-VOLTAGE SWITCHING
PACKAGE DRAWING (UNIT: mm)
The 2SC4942 is a transistor developed for high-speed high-
voltage switching. This transistor is ideal for use in switching
devices such as switching regulators and DC/DC converters.
FEATURES
• New package with dimensions in between those of small
signal and power signal package
• High voltage
• Fast switching speed
• Complementary transistor with the 2SA1871
