This is a through-hole part in a DO-201AA (DO-27) axial package, intended for automotive-grade transient suppression on 5 V or 6 V supply rails where the bidirectional configuration handles both positive and negative surges without needing a series diode. ## Voltage ratings and what they mean for rail protection The reverse standoff voltage of 5.8 V is the maximum continuous DC voltage the TVS can sit across without conducting appreciable leakage — ideal for protecting a 5 V logic rail or a 6 V sensor supply. The minimum breakdown of 6.45 V ensures the device does not clip the rail during normal operation. At the full 143 A peak pulse current (10/1000 µs waveform), the clamping voltage rises to 10.5 V max. This means a downstream component rated for at least 12 V sees a safe voltage during the surge event. ## Lifecycle reality — obsolete, sourced on the spot market Vishay has marked the 1.5KE6.8CAHE3/51 as obsolete. A cross-reference to an active Vishay TransZorb with the same 1500 W rating and 6.8 V bidirectional specification may exist, but no pin-compatible direct replacement is documented in the official lifecycle data.","metaTitle":"Vishay 1.5KE6.8CAHE3/51 TVS, Bidirectional, 1500W, DO-201","metaDescription":"Vishay 1.5KE6.8CAHE3/51 TransZorb TVS, 1500W peak pulse, 6.8V bidirectional, AEC-Q101.
