Characteristics and Application
SAC is a Transient Voltage Suppressor Diode in series with a compensation diode
for low capacitance.
Transient Voltage Suppressors may be used at various points in a circuit to
provide various degrees of protection.
Transient Voltage Suppressor provides excellent clamping capability.
Since the low incremental surge resistance.
For telecommumication : multi-protocol serial transceivers. Please refer as below:
-) Cellular
-) Universal series bus (USB) port production.
-) Instrumentation.
-) LAN / WAN equipment.
-) Peripherals.
-) High speed data lines.
Tow devices are used in parallel and opposite polarity for protecting one
bi-directional ines (FIG. 1), or with a steeling diode for protecting one
unidirectional (FIG. 2).
The low capacitance TVS series are used on high speeded interfaces such as
2
video line, I C RS-485, RS-422 and USB, for ESD protection the lines which
have signal, or data. Please refer as below:
