For a BOM that already carries this TVS, the immediate decision is whether to secure lifetime-buy quantities now or plan a qualification run on a replacement. ## 1500W peak pulse — the protection envelope The 94V reverse standoff voltage is the DC working voltage — the TVS draws negligible leakage below this level, so it sits invisibly on a 94V rail or a 94V bus. Once the transient exceeds the minimum breakdown voltage of 105V, the device starts conducting and holds the line to 152V, protecting downstream silicon rated for that voltage class. ## Bidirectional — one device for both polarities This is a single bidirectional channel, meaning it clamps equally on positive and negative transients. For AC signal lines, data pairs, or bipolar power rails, one bidirectional TVS replaces two back-to-back unidirectional devices, saving board space and reducing component count. The symmetrical breakdown characteristic also simplifies layout — there is no polarity to observe during assembly. ## Temperature range and package — industrial-grade through-hole The DO-201AA / DO-27 axial package is a through-hole form factor — it handles higher surge energy than a surface-mount equivalent because the leadframe and body dissipate heat into the PCB traces and the surrounding air. The Bulk packaging means the parts are shipped loose in a bag or tube, not on tape-and-reel, which is typical for through-hole components destined for hand-insertion or wave-solder lines.","metaTitle":"1.5KE110CA-E3/51 Vishay TVS, 1500W Bidirectional, Last Buy","metaDescription":"Vishay 1.5KE110CA-E3/51 TransZorb® TVS, 1500W peak pulse, 94V standoff, 152V clamp, bidirectional, DO-201AA.
