Table 12. Ringing Return Access Switch (SW1)
1.
At 25 °C, maximum voltage rating has a temperature coefficient of +0.167 V/°C.
2. This parameter is not tested in production; it is guaranteed by design and device characterization.
3. Applied voltage is 100 Vp-p square wave at 100 Hz to measure dV/dt sensitivity at 200 V/μs typical with no switch turn-on. In the case of
dV/dt induced turn-on at higher dV/dt and amplitude, the design objective is no damage to at least 2000 V/μs and full voltage. A known con-
dition that can cause damage is initial current flow prior to the application of the dV/dt and the sudden application of reverse bias with dV/dt
induced switch turn-off. In this case, no damage will occur for dV/dt up to 2000 V/μs as guaranteed by design and characterization.
Table 13. Test-In Access Switches (SW3 and SW6)
1. At 25 °C, maximum voltage rating has a temperature coefficient of +0.167 V/°C.
2. This parameter is not tested in production; it is guaranteed by design and device characterization.
3. Test in access switches current limit will be > tip and ring break switches current limit.
4. Applied voltage is 100 Vp-p square wave at 100 Hz to measure dV/dt sensitivity at 200 V/μs typical with no switch turn-on. In the case of
dV/dt induced turn-on at higher dV/dt and amplitude, the design objective is no damage to at least 2000 V/μs and full voltage. A known con-
dition that can cause damage is initial current flow prior to the application of the dV/dt and the sudden application of reverse bias with dV/dt
induced switch turn-off. In this case, no damage will occur for dV/dt up to 2000 V/μs as guaranteed by design and characterization.
