The NTSB20U100CTT4G is an onsemi dual common-cathode Schottky power rectifier rated at 20 A and 100 V, built on fine-lithography trench-based Schottky technology that delivers a very low forward voltage without the high reverse leakage penalty typical of planar Schottky devices. It integrates two matched 10 A diodes sharing one cathode in a single D2PAK-3 (TO-263-2, case 418B-04) surface-mount package, with the exposed tab tied to the cathode for both electrical connection and heat sinking.
Key ratings include a maximum forward voltage of 0.79 V at 10 A, 800 µA maximum reverse current at rated 100 V, 20 A average rectified current per device (10 A per diode) and 150 A non-repetitive surge capability. The trench platform delivers fast switching with exceptional temperature stability, low power loss, low thermal resistance and a -40°C to +150°C junction range, making it a strong output rectifier for high-efficiency supplies.

FAQ
Q: Can it handle 20 A continuously? 20 A is the device total at rated conditions with proper heatsinking, equal to 10 A per diode leg.
Q: Why choose trench Schottky? It keeps forward voltage low without the leakage and thermal-runaway tradeoff common in planar Schottky rectifiers.
Q: Any layout cautions? Solder the tab to a large copper area with thermal vias, and keep the junction within 150°C.
