TISP31xxF3 (MV) Overvoltage Protector Series
APPLICATIONS INFORMATION
Protection Voltage
The protection voltage, (V(BO) ), increases under lightning surge conditions due to thyristor regeneration. This increase is dependent on the
rate of current rise, di/dt, when the TISP ? device is clamping the voltage in its breakdown region. The V(BO) value under surge conditions can
be estimated by multiplying the 50 Hz rate V(BO) (250 V/ms) value by the normalized increase at the surge’s di/dt (Figure 7 ). An estimate of the
di/dt can be made from the surge generator voltage rate of rise, dv/dt, and the circuit resistance.
As an example, the ITU-T K.21 1.5 kV, 10/700 μ s surge has an average dv/dt of 150 V/ μ s, but, as the rise is exponential, the initial dv/dt is
higher, being in the region of 450 V/ μ s. The instantaneous generator output resistance is 25 ? . If the equipment has an additional series
resistance of 20 ? , the total series resistance becomes 45 ? . The maximum di/dt then can be estimated as 450/45 = 10 A/ μ s. In practice, the
measured di/dt and protection voltage increase will be lower due to inductive effects and the finite slope resistance of the TISP ? breakdown
region.
Capacitance
Off-state Capacitance
The off-state capacitance of a TISP ? device is sensitive to junction temperature, TJ, and the bias voltage, comprising of the d.c. voltage, VD,
and the a.c. voltage, Vd. All the capacitance values in this data sheet are measured with an a.c. voltage of 100 mV. The typical 25 ° C variation
of capacitance value with a.c. bias is shown in Figure 16. When VD >> Vd, the capacitance value is independent on the value of Vd. The
capacitance is essentially constant over the range of normal telecommunication frequencies.
