Electrical Specifications (TA = 25 °C)

The minimum and/or maximum limits specified for the parameters are based on the absolute system. The alge-

braic sign only applies to the direction of the parameter. These requirements apply to either the TIP or RING termi-

nal; however, the device is capable of simultaneous Tip and Ring surges and continuous current, as noted below in

Tip and Ring leads. See Figure 3 and Table 5 for symbol and test condition definition.
