UPS5817e3 and UPS5819e3
POWERMITE 1™ SURFACE MOUNT
1 AMP 20 and 40 V SCHOTTKY RECTIFIERS
DESCRIPTION
The UPS5817e3 and UPS5819e3 offer a small and powerful surface mount
package that is RoHS compliant for a 1 Amp rated Schottky. These ratings
are found only in much larger packages. They are ideal for surface mount
applications that operate at high frequencies with their “hot carrier” features
that provide extremely fast switching. The very low thermal resistance of the
patented Powermite 1™ package design with a full metallic bottom and
unique locking tab act as an efficient heat path to a heat sink mounting permitting
cooler operating junction temperatures for minimal reverse leakage currents
and lower power loss. It is also ideal for automatic insertion equipment.

Amp
• Forward surge current (IFSM) 8.3 ms single half-sine
waveform superimposed on rated load (JEDEC
Method): 50 Amps
• Thermal resistance junction to case (bottom): 10 oC/W
• Thermal resistance (RθJA): 240 oC/W on PCB with FR4
using 1 oz Copper and recommended mounting pad
size (see pad layout next page)

APPLICATIONS / BENEFITS
• High current capability with low forward voltage
• Guard-ring-die construction for transient protection
• Silicon Schottky (hot carrier) rectifier for minimal trr
and minimal reverse recovery voltage
• Elimination of reverse-recovery oscillations to
reduce need for EMI filtering
• For use in high-frequency switching power supplies,
inverters, free wheeling, charge pump circuits and
polarity protection applications
• Lower forward power loss and high efficiency
• Low inductive parasitics (<2nH) for minimal Ldi/dt
effects
• Robust package configuration for pick-and-place
handling
• Full-metallic bottom eliminates flux entrapment
• Small foot print with 0.100 x 0.160 inches (see
mounting pad details on last page)
MECHANICAL AND PACKAGING
