The -55°C to 175°C operating junction range covers the full automotive temperature envelope, including engine-bay ambient heat soak. ## Clamping performance under surge With a breakdown voltage of 6.12V minimum and a reverse standoff of 5.5V, the diode begins conducting just above the normal rail voltage. The 1500W peak pulse rating is the headline energy-handling figure, but the clamping voltage at the actual surge current is what determines whether the protected IC survives. For a 5V rail, the 10.8V clamp provides roughly 2x margin above the rail — typical for automotive transient protection per ISO 7637-2 pulse 5a. ## Obsolete — sourcing through surplus channels Vishay has marked the 1.5KE6.8HE3/73 as obsolete.","metaTitle":"1.5KE6.8HE3/73 Vishay Zener TVS, AEC-Q101, 1500W","metaDescription":"Vishay 1.5KE6.8HE3/73 Zener TVS diode, 1500W peak pulse, AEC-Q101 automotive qualified.
