The data of Figures 1, 2, and 3 is basad upon dc conditions. For use in common rectifier circuits, Table 1 indicates suggested factors for an equivalent dc voltage to use for conservative design, that is: TA(max) • Tjlmaxl ~ RflJAfplAVI - RejApR(AV) I1' where TAlmax) " Maximum allowable ambient temperature Tj(max) * Maximum allowable junction temperature (12S°C or the temperature at which thermal runaway occurs, whichever is lowest) PFIAV) ' Average forward power dissipation PR (A VI • Average reverse power dissipation RJJA • Junction-to-ambient thermal resistance Figures 1, 2. and 3 permit easier use of equation (1) by taking reverse power dissipation and thermal runaway into consideration. The figures solve for a reference temperature as determined by equation (2). TR-Tj( m a x )-R 9 j A P R ( A V ) (2) Substituting equation (2) into equation (1} yields: VR(equiv)-Vin(PK) * F (41 The factor P is derived by considering the properties of the various rectifier circuits and the reverse characteristics of Schottky diodes.
