5 TVS APPLICATION NOTES: Transient Suppressors may be used at various points in a circuit to provide various degrees of protection. The following is a typical linear power supply with transient voltage suppressor units plaved at different points. All provide protection of the load. Transient Suppressor 1 provides maximum protection. However, the system will probably require replacement of the line fuse(f) since it provides a dominant portion of the series impedance when a surge is encountered. Hower, we do not recommend to use the TVS diode here, unless we can know the electric circuit impedance and the magnitude of surge rushed into the circuit. Otherwise the TVS diode is easy to be destroyed by voltage surge. Transient Suppressor 2 provides execllent protection of circuitry excluding the transformer(t). However, since the transformer is a large part of the series impedance, the chance of the line fuse opening during the surge condition is reduced. Transient Suppressor 3 provides the load with complete protection. It uses a unidirectional Transient Suppressor, which is a cost advantage. The series impedance now includes the line fuse, transformer, and bridge rectifier(b) so failure of the line fuse is further reduced. If onlt Transient Suppressor 3 is in use, then the bridge rectifier is unprotected and would require a higher voltage and current rating to prevent failure by transients. Any combination of this three, or any one of these applivations, will prevent damage to the load. This would require varying trade-offs in power supply protection versus maintenance(changing the time fuse). An additional method is to utilize the Transient Suppressor units as a controlled avalanche bridge. This reduces the parts count and incorporated the protection within the bridge rectifier. RECOMMENDED PAD SIZES The pad dimensions should be 0.0"(0.25mm) longer than the contact size, in the lead axis. This allows a solder filler to form, see figure below.
