For a BOM that depends on this TVS, the procurement decision is now time-sensitive: once the last-buy period ends, the only channel will be independent surplus or broker inventory. ## Clamping performance for a 171V rail This is a unidirectional TransZorb® TVS diode with a 171V reverse standoff voltage — it sits across a DC bus or signal line rated up to 171V and stays out of conduction during normal operation. When a transient exceeds the 190V minimum breakdown voltage, the device clamps at 274V maximum (at the 5.5A peak pulse current, 10/1000µs waveform), shunting the surge energy to ground. For a 274V clamp, the device can absorb a 5.5A surge before the junction temperature exceeds the safe operating area — a typical fit for protecting 170V DC buses, telecom line cards, or industrial power supplies against lightning-induced or inductive-load transients. The DO-201AA axial-lead package (also known as DO-27) is through-hole — rework-friendly with a soldering iron or hot-air station, and the large body dissipates heat well during repetitive surge events.","metaTitle":"Vishay 1.5KE200A-E3/51 TVS Diode, 1.5kW, 274V Clamp","metaDescription":"Vishay 1.5KE200A-E3/51 TransZorb® TVS, 171V standoff, 274V clamp, 1.5kW peak pulse.
