1.20 Pcs — 15SQ045 Schottky Rectifier (Si) Key specifications Model: 15SQ045 Forward (maximum average) current: 15 A Repetitive peak reverse voltage (VRRM): 45 V Forward voltage: 0.55 V at DC 10 A Material: Silicon (Si) surge current capability, low leakage Why this product matters Lower power loss: The low forward voltage (0.55 V at 10 A) reduces conduction losses, improving overall circuit efficiency and lowering heat generation. Reliable under surge: surgecurrent capability gives robust protection against transient currents and startup inrush. Stable standby performance: Low leakage current reduces unwanted drain in standby or lowpower conditions. What it does and where it fits Function: Fast, lowdrop rectification for DC circuits — suitable for general rectifier, freewheeling/flyback, reversepolarity protection, and power conversion roles. Compatibility: Designed for applications requiring up to 15 A continuous forward current and up to 45 V reverse voltage. Verify package and footprint against your board layout or supplier datasheet before assembly. Practical use scenarios Switching power supplies and DCDC converters: Use as output rectifier to improve efficiency and reduce heat in current sections. Motor drivers and inductive loads: Use as a freewheeling or flyback diode to absorb inductive spikes and protect switching devices during transients. Battery charging and protection circuits: Use for reversepolarity protection and lowloss conduction in midvoltage (≤45 V) battery systems. Performance notes Typical forward voltage is approximately 0.55 V measured at DC 10 A; actual Vf will vary with current and temperature. Maximum average forward current is 15 A; ensure adequate thermal management for continuous current operation. Low leakage and silicon Schottky characteristics contribute to improved efficiency and reduced power dissipation. Ordering and verification Supplied as indicated: 1.20 Pcs 15SQ045.
