PowerDI5
DESCRIPTION
The UPDS1045 offers a small and powerful surface mount package for a
45 Volt 10 Amp rated Schottky with very low forward voltage and low
leakage current. For critical applications requiring very fast switching,
these Schottky higher reverse voltage ratings with their “hot carrier”
features provide extremely fast switching to replace conventional ultrafast
rectifiers. The very low thermal resistance of the PowerDI5 package
design permits cooler operating junction temperatures for minimal reverse
leakage currents and lower power loss.

APPEARANCE
PowerDI™5
FEATURES
Guard ring die construction for transient protection
Low power loss, high efficiency
Low forward voltage drop
Low reverse leakage current
High junction temperature capability
High forward surge current capability
Environmentally friendly molding compound (no Br, Sb)
Low inductive parasitics for minimal Ldi/dt effects
Lead-Free Finish & RoHS Compliant per EU Directive Rev
13.2.2003 (glass and high temperature solder exemptions

Single half sine-wave Superimposed on Rated Load
(IFSM): 275A
Thermal Resistance Junction to case bottom (RθJC) or
Soldering Point (RθJS): 0.8oC/W
Thermal Resistance (RθJA): 85oC/W (Note 1), 70oC/W
(Note 2), 40oC/W (Note 3) junction to ambient air (see last
page)
Notes: 1. FR-4 PCB, 2 oz. Copper, minimum recommended pad layout (pg 4)
2. Polyimide PCB, 2 oz. Copper, minimum recommended pad layout (pg 4)
3. Polyimide PCB, 2 oz. Copper with larger Cathode pad dimensions
13.2 mm x 10.1 mm and Anode pad dimensions 4.0 mm x 2.2 mm
APPLICATIONS / BENEFITS
Silicon Schottky (hot carrier) rectifier for minimal
trr and elimination of reverse-recovery oscillations
to reduce need for EMI filtering
For use in high-frequency switching power
supplies, inverters, free wheeling, polarity
protection, and “O-Ring” applications
Low power loss and high efficiency
Robust package configuration for pick-and-place
handling
Full-metallic bottom eliminates flux entrapment
