It is a single bidirectional channel device; the TransZorb construction delivers fast avalanche response with no power line protection feature — it is a pure transient suppressor, not a crowbar or filter. ## AEC-Q101 qualification and the TransZorb series The Automotive, AEC-Q101, TransZorb designation means this part passed the full automotive stress suite: temperature cycling, high-temperature reverse bias, and humidity bias at the die level. The 175°C maximum junction temperature rating allows placement near exhaust manifolds or turbocharger heat zones where ambient soak exceeds 125°C.","metaTitle":"Vishay 1.5KE75CHE3/73 TransZorb TVS, 1500W, 60.7V Standoff","metaDescription":"Automotive AEC-Q101 TransZorb Zener TVS diode, 1500W peak pulse, 60.7V standoff, 109V clamp.
