SWITCHMODE Series

NPN Silicon Power Transistors

The BUS98 and BUS98A transistors are designed for high–voltage, high–speed,

power switching in inductive circuits where fall time is critical. They are particularly

suited for line–operated switchmode applications such as:

• Switching Regulators

• Inverters

• Solenoid and Relay Drivers

• Motor Controls

• Deflection Circuits

Designer’s Data for “Worst Case” Conditions — The Designer’s Data Sheet permits the design of most circuits entirely from the information presented. SOA Limit

curves — representing boundaries on device characteristics — are given to facilitate “worst case” design.
