1. 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_θJF + R_θFA = R_θJA where the
foot thermal reference is defined as the normal solder mounting surface of the device's leads. R_θJF is guaranteed by design; however,
R_θCA is determined by the PCB design. Actual maximum continuous current is limited by the application's design.
2. Pulse test: Pulse Width = 300µs.
