DESCRIPTION
The BU505 is a high voltage NPN fastswitching transistor designed to be used in lighting application, like electronic ballas for fluorescent lamps.
Its characteristics make it also ideal for power supplies.

■ HIGH VOLTAGE CAPABILITY
■ VERY HIGH SWITCHING SPEED
■ LOW BASE-DRIVE REQUIREMENTS

APPLICATIONS
■ ELECTRONIC BALLASTS FOR
   FLUORESCENT LIGHTING
■ SWITCH MODE POWER SUPPLIES
