† All typical values are at TA = 25°C.
NOTES: 3. The current flows through one TIP (or RING) terminal and one of the GND terminals. The voltage is measured between the other
TIP (or RING) terminal and the other GND terminal. Measurement time ≤ 1 ms.
4. The negative value of trip current refers to the current flowing out of TIP or RING on the line side that is sufficient in magnitude to
trigger the SCRs. Measurement time ≤ 1 ns.
5. The critical dv/dt is measured using a linear rate of rise with the maximum voltage limited to – 50 V with VS connected to TIP or RING
being measured.
