Notes

1. Guaranteed by design, not tested.

2. Unit will shut down above approximately 45 V but will be undamaged and will

restart when voltage drops into normal range.

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

which Vout is within 1% of final value.

4. Transition time > 10 µS.

5. Tested on release from inhibit.

6. Shall not compromise DC performance.

7. SMFL283R3S current and power are at 25°C only.

Electrical Characteristics: -55°C to +125°C Tc, 28 VDC Vin, 100% load, RHA level O, unless otherwise specified.
