| UPDS1045 10 Amp Schottky Barrier Rectifier PowerDITM 5 SCOTTSDALE DIVISION 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 PowerDITM5 package design permits cooler operating junction temperatures for minimal reverse leakage currents and lower power loss. APPEARANCE WWW .Microsemi .C OM PowerDITM5 IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com 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 per Annex Notes 5 and 7 therein) 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 MAXIMUM RATINGS * * Junction and Storage Temperature (TJ, TSTG): -65 to +150oC Average Rectified Output Current (IO): 10 Amps for Single phase, half wave, 60Hz, resistive or inductive load (also see Figure 5).
