Notes
1. Maximum permissible ambient temperature is dependent on internal dissipation. T_j is the discriminating factor.
T_j = (R_th(j-a) × P_tot) + T_amb, where P_tot is the total dissipation in the package.
2. Equivalent to discharging a 100 pF capacitor through a 1.5 kΩ series resistor.
3. Equivalent to discharging a 200 pF capacitor through a 25 Ω series resistor and a 2.5 µH series inductance.
