RRA ee eee ttky Rectifiers SWITCHMODE Schottky power rectifiers with the high speed and low forward voltage drop characteristic of Schott- ky's metal/silicon junctions are produced with ruggedness and temperature performance comparable to silicon-junction rectifiers. Ideal for use in low voltage, high frequency power supplies and as very fast clamping diodes, these devices feature switching times less than 10 ns, and are offered in current ranges from 0.5 to 300 amperes, and reverse voltages to 60 volts. In some current ranges, devices are available with junction Table 24. Schottky Rectifiers temperature specifications of 125C, 150C, 175C. Devices with higher Ty ratings can have significantly lower leakage currents, but higher forward-voltage specifications. These parameter tradeoffs should be considered when selecting devices for applications that can be satisfied by more than one device type number. All devices are connected cathode to case or cathode to heatsink, where applicable. Reverse polarity may be avail- able on some devices upon special request.
