A. Pulsed width limited by maximum junction temperature, TJ(MAX)=5 C. B. The value of RθJA is measured with the device mounted on in FR- board in a still air environment with maximum junction temperature TJ(MAX)=5 C (initial temperature ). C. TJ(MAX)=5 C,using junction-to-case thermal resistance (RθJC) is more useful in additional heat sinking is used. nc pf ns The products and product specifications contained herein are subject to change without notice to improve performance characteristics.
