Description
The BU900TP is a planar, monolithic, high voltage
power TRILINTON™ with a built-in active Zener
clamping circuit. This device has been specifically
designed for unclamped, inductive applications
such as ignition systems, switching regulators,
and wherever high voltage and high robustness is
required.
