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 placed at
different points. All provide protection of the load.
FIGURE 1
Transient Voltage Suppressors 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.
However, 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.
Dimensions in inches and (millimeters)
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 of the line fuse is further reduced. If only Transient Voltage
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 these three, or any one of these applications, 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 Voltage Suppressor units as a controlled avalanche bridge.
This reduces the parts count and incorporates the protection within the bridge rectifier.
FIGURE 2
RECOMMENDED PAD SIZES
The pad dimensions should be 0.010"(0.25mm) longer than the contact size, in the lead axis.
This allows a solder fillet to form, see figure below. Contact factory for soldering methods.
