PL IA NT Features CO M Formerly The P650-U & P850-U Series are currently available, but not recommended for new designs. Bourns(R) TBU-DT Series is preferred. brand *R oH S Extremely high speed performance Blocks high voltages and currents Low insertion loss Two TBU(R) protectors in one small package Very high bandwidth; GHz compatible RoHS compliant*, UL Recognized P650-U and P850-U Series TBU(R) High-Speed Protectors Transient Blocking Units - TBU(R) Devices (R) Bourns Model P650-U and P850-U products are high-speed, unidirectional protection components, constructed using MOSFET semiconductor technology, designed to protect against faults caused by short circuits, AC power cross, induction and lightning surges. The TBU(R) high-speed protector, triggering as a function of the MOSFET, blocks surges and provides an effective barrier behind which sensitive electronics are not exposed to large voltages or currents during surge events. The TBU(R) device is provided in a surface mount DFN package and meets industry standard requirements such as RoHS and Pb Free solder reflow profiles.

TBU(R) devices have matte-tin termination finish. Suggested layout should use non-solder mask define (NSMD). Recommended stencil thickness is 0.10-0.12 mm (.004-.005 in.) with stencil opening size 0.025 mm (.0010 in.) less than the device pad size. As when heat sinking any power device, it is recommended that, wherever possible, extra PCB copper area is allowed. For minimum parasitic capacitance, do not allow any signal, ground or power signals beneath any of the pads of the device.
