The 40.2 V standoff means the diode does not conduct appreciably below that rail voltage, so it sits across a 36 V or 40 V supply bus without loading it. When a transient exceeds the breakdown threshold (44.7 V min), the device clamps at 64.8 V maximum, shunting up to 23.1 A away from the protected circuitry. This is a unidirectional device (one channel); the cathode band marks the anode-to-ground orientation. For bidirectional clamping on an AC line or a bipolar rail, two unidirectional parts back-to-back or a single bidirectional 1.5KE series part is the usual call. ## Sourcing and lifecycle posture The -/54 suffix indicates the tape-and-reel packaging variant (1500-piece reel). The same die in bulk or ammo-pack carries a different ordering suffix; confirm the packaging requirement against your BOM line before committing the order code.","metaTitle":"1.5KE47A-E3/54 Vishay TVS, 1500W, 40.2V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE47A-E3/54 TransZorb® TVS diode, 1500W peak pulse, 40.2V reverse standoff, unidirectional, DO-201AA axial.
