Reverse leakage is 500 µA at 40 V — this is the worst-case figure at rated Vr; actual leakage at lower reverse bias is lower, but the spec matters for standby power budgets in always-powered automotive modules. ## Automotive AEC-Q101 — under-hood and cabin grade The automotive series designation means the parts are PPAP-capable and manufactured on an IATF 16949 line. ## Active lifecycle — sourcing posture Reel and cut-tape packaging options are available, with the D²PAK footprint compatible with standard reflow profiles.","metaTitle":"Vishay SBLB1640CTHE3_B/I Schottky Rectifier, 8A, 40V","metaDescription":"Vishay SBLB1640CTHE3_B/I dual common-cathode Schottky rectifier, 8A per diode, 40V Vr, 550mV Vf, TO-263AB (D²PAK).

This is typical for Schottky diodes — the Schottky barrier inherently provides fast switching without stored charge, so recovery time is not a limiting factor in most automotive and power-supply applications."},{"question":"What package and mounting does SBLB1640CTHE3_B/I use?","answer":"The device is supplied in a TO-263-3 (D²PAK) surface-mount package with 2 leads plus a tab (the third terminal is the tab, electrically common to the cathode pair). The supplier device package is TO-263AB. The tab must be soldered to the PCB copper pour for thermal management."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/SBLB1640CTHE3_B-I","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/SBLB1640CTHE3_B-I when reusing this data.
