ELECTRICAL CHARACTERISTICS
T
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 testing requirements.
A
= –40 °C to +85 °C, unless otherwise specified.
1. Choice of secondary protector should ensure this rating is not exceeded.
2. This parameter is not tested in production.
3. Applied voltage is 100 Vp-p square wave at 100 Hz.
