Product Description
Vishay VBT4045BP-E3/8W is a high-power surface mount Schottky diode featuring a patented Trench MOS Barrier Schottky (TMBS) technology. This 45 V, 40 A diode comes in a compact 3-pin TO-263 package, optimized for efficient power rectification in various industrial and commercial electronics.
The TMBS structure minimizes minority carrier injection, significantly reducing stored charge and consequently improving switching speeds compared to planar Schottky rectifiers. This makes the diode highly suitable for modern AC/DC switch-mode power supplies and DC/DC converters where efficiency and thermal performance are critical.
Key electrical characteristics include a maximum continuous forward current of 40 A, a peak reverse repetitive voltage of 45 V, and a low forward voltage drop of 630 mV that helps reduce power dissipation. The device withstands peak surge currents of up to 240 A, ensuring reliability under transient conditions.
The diode is rated for operating temperatures from -40°C up to 150°C, making it robust for demanding industrial environments. Its surface mount TO-263 package dimensions of 10.45 mm length, 4.83 mm width, and 9.14 mm height facilitate easy PCB integration.
Maximum continuous forward current: 40 A. Peak reverse repetitive voltage: 45 V. Maximum forward voltage drop: 630 mV. Peak non-repetitive forward surge current: 240 A. Operating temperature range: -40°C to 150°C. Compact TO-263 surface mount package.
