Electrical Characteristics

°C to +85 °C, unless otherwise specified.

Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are

the result of engineering evaluations. Typical values are for information purposes only and are not part of the test-

ing requirements.

* This parameter is not tested in production. Choice of secondary protector should ensure this rating is not exceeded.

† Applied voltage is 100 Vp-p square wave at 100 Hz.
