TVS APPLICATION NOTES:
Transient Voltage 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
Transient Voltage 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 Voltage 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 Voltage Suppressor 3 provides the load with complete protection. It uses a unidirectional
Transient Voltage Suppressor, which is a cost advantage. The series impedance now includes the line fuse,
transformer, and bridge rectifier(B) so failure
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 Trans
