MBR120VLSFT1 Surface Mount Schottky Power Rectifier Plastic SOD-123 Package . . . using the Schottky Barrier principle with a large area metal-to-silicon power diode. Ideally suited for low voltage, high frequency rectification or as free wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical to the system. This package also provides an easy to work with alternative to leadless 34 package style. Because of its small size, it is ideal for use in portable and battery powered products such as cellular and cordless phones, chargers, notebook computers, printers, PDAs and PCMCIA cards. Typical applications are ac/dc and dc-dc converters, reverse battery protection, and “Oring” of multiple supply voltages and any other application where performance and size are critical.

Typical Operating Temperature Derating* 20 r(t), TRANSIENT THERMAL RESISTANCE * Reverse power dissipation and the possibility of thermal runaway must be considered when operating this device under any reverse voltage conditions. Calculations of TJ therefore must include forward and reverse power effects. The allowable operating TJ = TJmax - r(t)(Pf + Pr) where TJ may be calculated from the equation: r(t) = thermal impedance under given conditions, Pf = forward power dissipation, and Pr = reverse power dissipation This graph displays the derated allowable TJ due to reverse bias under DC conditions only and is calculated as TJ = TJmax - r(t)Pr, where r(t) = Rthja. For other power applications further calculations must be performed. 1000 D = 0.5 100 0.2 0.1 0.05 P(pk) 10 0.01 t1 t2 DUTY CYCLE, D = t1/t2 1 SINGLE PULSE JA = 321.8 °C/W Test Type > Min Pad < Die Size 38x38 @ 75% mils 0.1 0.000001 0.00001 0.0001 0.001 0.01 0.1 t1, TIME (sec) Figure 9.
