electrical characteristics
APPLICATIONS INFORMATION
The electrical characteristics of a thyristor overvoltage protector are strongly dependent on junction
temperature, TJ. Hence a characteristic value will depend on the junction temperature at the instant of
measurement. The values given in this data sheet were measured on commercial testers, which generally
minimise the temperature rise caused by testing.
application circuit
Figure 3 shows a typical TISP6151xx SLIC card protection circuit. The incoming line wires, R and T, connect
to the relay matrix via the series over-current protection. Fusible resistors, fuses and positive temperature
coefficient (PTC) resistors can be used for over-current protection. Resistors will reduce the prospective
current from the surge generator for both the TISP6151xx and the ring/test protector. The TISP7xxxF3
protector has the same protection voltage for any terminal pair. This protector is used when the ring generator
configuration maybe ground or battery-backed. For dedicated ground-backed ringing generators, the
TISP3xxxF3 gives better protection as its inter-wire protection voltage is twice the wire to ground value.
Relay contacts 3a and 3b connect the line wires to the SLIC via the TISP6151xx protector. The protector gate
reference voltage comes from the SLIC negative supply (VBAT). A 220 nF gate capacitor sources the high
gate current pulses caused by fast rising impulses.
