Notes

1. MSA2860S specifications are at 25°Tc only, contact your Interpoint

representative for more information on over temperature specs.

°C to 125°C (case) is 5% (max).

3. Indefinite short circuit protection not guaranteed above 125°C (case).

4. Recovery time is measured from application of the transient to point at which

5. Transition time >10µs.
