Decreased base spread resistance in these transistors also allows a wide driving range for simplified design of the horizontal deflection circuit
With the introduction today of its new BU45xx range of 1500 V horizontal deflection transistors, Philips Semiconductors has made it significantly easier for TV and monitor manufacturers to achieve these four important objectives, all of which depend on deflection circuit
They can be used as clamping networks for SMPS, dampers, and modulator diodes for the deflection circuits
in CRTs freewheeling diodes for inductive loads.
The high speed "A" devices are intended for high voltage, fast switching applications up to 100kHz such as induction heating, induction cooking, 480 to 575VAC offline inverters, flyback power supplies, UPS and microwave ovens, horizontal and vertical deflection circuits
