STPS41L60C
Power Schottky rectifier
Features
Low forward voltage drop
Negligible switching losses
Low thermal resistance
Avalanche capability specified
Description
These dual center tap Schottky rectifiers are
suited for switch mode power supplies and high
frequency DC to DC converters.
Packaged in D2PAK , I 2PAK and TO-220AB, this
device is intended for use in low voltage, high
frequency inverters, free-wheeling and polarity
protection applications.

1 Characteristics
When the diodes 1 and 2 are used simultaneously :
ΔTj(diode 1) = P(diode1) x Rth(j-c)(Per diode) + P(diode 2) x Rth(c)
To evaluate the conduction losses use the following equation:
P = 0.42 x IF(AV) + 0.007 x IF2(RMS)
