LOW DROP POWER SCHOTTKY RECTIFIER
STPS41H100CG/CT/CRSeptember 2002-Ed:2A
LOW DROP POWER SCHOTTKY RECTIFIER
Dual center tab Schottky rectifier suitedfor Switch
Mode Power Supply and high frequency DCto DC
converters.
PackagedinD2 PAK,I2 PAK and TO-220AB, this
deviceis intended for usein high frequency
inverters.
DESCRIPTION Negligible switching losses Low leakage current Good tradeoff between leakage current and for-
ward voltage drop Low thermal resistance

STPS41H100CG/CT/CRPulse test:*tp= 380 μs,δ <2% evaluate the conduction losses use the following equation:
P=0.58xIF(AV)+ 0.0045IF2 (RMS)
STATIC ELECTRICAL CHARACTERISTICS (per diode)
When the diodes1 and2 are used simultaneously: Tj(diode1)= P(diode1)x Rth(j-c)(Per diode)+ P(diode2)x Rth(c)
