OSP PRODUCTS March, 2016 Bourns® Model 12P Series 1-Pin SS Overvoltage Protector Modules to be Discontinued Bourns has decided to discontinue the Model 12P Series 1-Pin SS Overvoltage Protector Modules. A lack of sales volume and diminishing demand necessitates this action. The suggested replacement series is the Model 14P which offers improved technology. The Model 14P Series has the same shape and function as the obsolete series but the technology is different. The 14P Series uses a Gas Discharge Tube (GDT) with Polymer PTC (PPTC) resettable fuse and the 12P Series used a solid-state device with heat coils.
