Characteristics STPS10120C2/8
1 Characteristics When the diodes 1 and 2 are used simultaneously :
Tj(diode 1) = P(diode 1) x Rth(j-c)(per diode) + P(diode 2) x Rth(c)
To evaluate the maximum conduction losses use the following equation :
P = 0.60 x IF(AV) + 0.02 IF2 (RMS)

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOP ACK specifications are available at: .
