schottky barrier

Fig.1. Maximum forward dissipation P

F = f(IF(AV)) per

diode; square current waveform where

F(AV) =IF(RMS) x √D.

Fig.2. Maximum forward dissipation P

F = f(IF(AV)) per

diode; sinusoidal current waveform where a = form

factor = I

F(RMS) / IF(AV).

Fig.3. Typical and maximum forward characteristic

F = f(VF); parameter Tj

Fig.4. Typical reverse leakage current per diode;

R = f(VR); parameter Tj

Fig.5. Typical junction capacitance per diode;

d = f(VR); f = 1 MHz; Tj = 25˚C to 125 ˚C.

Fig.6. Transient thermal impedance per diode;

th j-mb = f(tp).
