Thermal Response Rectifier Device Data 3 MBR2035CT MBR2045CT HIGH FREQUENCY OPERATION Since current flow in a Schottky rectifier is the result of majority carrier conduction, it is not subject to junction diode forward and reverse recovery transients due to minority carrier injection and stored charge. Satisfactory circuit analysis work may be performed by using a model consisting of an ideal diode in parallel with a variable capacitance. (See Figure 10.) Rectification efficiency measurements show that operation will be satisfactory up to several megahertz. For example, relative waveform rectification efficiency is approximately 70 percent at 2.0 MHz, e.g., the ratio of dc power to RMS power in the load is 0.28 at this frequency, whereas perfect rectification would yield 0.406 for sine wave inputs. However, in contrast to ordinary junction diodes, the loss in waveform efficiency is not indicative of power loss; it is simply a result of reverse current flow through the diode capacitance, which lowers the dc output voltage. 1500 1000 C, CAPACITANCE (pF) 700 500 MAXIMUM 300 TYPICAL 200 150 0.05 0.1 0.2 0.5 1.0 2.0 5.0 10 20 50 VR, REVERSE VOLTAGE (VOLTS) Figure 10.
