* Trigger Current is defined as the minimum current drawn from tip and ring to turn on the SCR. The specification in this data sheet is Gate

Trigger Current, which is defined as the maximum current that can flow into the battery before the SCR turns on.

† Typical at 25 °C

‡ Twice ± dynamic current limit of break switches.

§ In some instances, the typical ON-state voltage can range as low as –25 V.
