Data Sheet
Series current-limiting fused resistors or PTC resistors should be chosen so as not to exceed the current rating of
the external secondary protector. Refer to the manufacturer’s data sheet for specifications.

ON-State Voltage§
V
* 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.
