UPS5817e3 Schottky Barrier Rectifier Main product characteristics IO 1A VRRM 20V Tj(MAX) 150ºC VF(MAX) 0.45V Features and benefits • • • • Low forward voltage drop Low profile package height Efficient heat path with integral locking bottom metal tab Low thermal resistance DO-216AA package Powermite 1 (DO-216AA) Description and applications Single schottky rectifier assembled in Powermite 1® package which features a full metallic bottom that eliminates possibility of solder flux entrapment during assembly. The package also incorporates a unique locking tab which acts as an efficient heat path from die to mounting plane for external heat sinking with very low thermal resistance junction to case (bottom). This product is suitable for use in switching and regulating power supplies and also charge pump circuits.

Calculations of TJ therefore must include forward and reverse power effects. The allowable operating TJ may be calculated from the equation: TJ = TJ max = r(t)(Pf+Pr) where r(t) = thermal impedance under given conditions. Pf = forward power dissipation, and Pr = reverse power dissipation This graph displays the de-rated allowable TJ due to reverse bias under DC conditions only and is calculated as TJ = TJ max-r(t) Pr, Where r(t)=Rthja. For other power applications further calculations must be performed.
