Minimum breakdown voltage is 67.5V, maximum clamping at peak pulse current (13.9A) is 109V. The 60.7V standoff rating means the diode stays off below that voltage — no leakage penalty on a nominal 48V bus. The 1500W peak pulse rating is the energy it absorbs in a single 10/1000 µs surge; above that the device fails short or open. ## Sourcing an obsolete TransZorb With an Obsolete lifecycle status, the 1.5KE75C-/73 is no longer manufactured by Vishay. No official successor or pin-compatible alternative is listed in the record.","metaTitle":"1.5KE75C-E3/73 Vishay TransZorb TVS, 1500W, 60.7V Standoff","metaDescription":"Vishay 1.5KE75C-E3/73 TransZorb bidirectional TVS diode, 1500W peak pulse, 60.7V standoff, 109V clamp.
