
DESCRIPTION
The UTC 2SC4242 is a high-voltage, high-speed switching
power transistor and designed particularly for 115 and 220V
switch mode applications, such as switching regulators,
inverters, DC-DC converter and general purpose power
amplifiers.

FEATURES
* Low saturation voltage.
* Switching time: tF=0.5μs (Max.)@ IC=5.0A
* High reliability
