Notes: 1. The value of θJA is measured with the device mounted on 1in2FR-4 board with 2oz. Copper, in a still air
environment with TA=25°C.The value in any a given application depends on the user's specific board
design. The current rating is based on the t ≤10s thermal resistance rating.
2. Repetitive rating, pulse width limited by junction temperature.
3. The θJA is the sum of the thermal impedence from junction to lead θJL and lead to ambient.
