1. Pulse test: Pulse Width = 300μs.
2. Guaranteed by design. Not subject to production testing.
3. Based on thermal dissipation from junction to ambient while mounted on a 1" x 1" PCB with optimized layout. A 5-second pulse on a
1" x 1" PCB approximates testing a device mounted on a large multi-layer PCB as in most applications. R
