This is a single-channel Zener-type suppressor in a through-hole DO-201AA (DO-27) axial package — a footprint that's been a workhorse in telecom rectifiers, industrial power supplies, and motor-drive snubber circuits for decades. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE110C-/73 as obsolete. For a BOM line that calls out this exact part number, the supply path runs through independent surplus and broker inventory. ## What the ratings mean for the protection decision The 89.2 V reverse standoff voltage is the DC or peak-AC operating level below which the diode draws negligible leakage — it won't clip a 72 V nominal bus. The 99 V minimum breakdown voltage is where conduction starts, and the 158 V max clamping voltage is the peak the protected circuit must survive at 9.5 A Ipp. The 1500 W rating at 10/1000 µs is the standard telecom surge waveform; for shorter pulses (8/20 µs) the peak power capability is higher.","metaTitle":"1.5KE110C-E3/73 Vishay TransZorb TVS, 1500W Bidirectional","metaDescription":"Vishay 1.5KE110C-E3/73 TransZorb TVS diode, 1500W peak pulse, bidirectional, 89.2V standoff, DO-201AA.
