For a production BOM, this part must be sourced through independent distribution — stock is fixed and finite. Every lot we quote is date-code verified and tested for authenticity before shipment; we do not ship mystery stock that surfaced years after the official last-time-buy closed. ## Key ratings — what drives the fit The minimum breakdown voltage is 28.5 V, and the clamping voltage at peak pulse current is 53.5 V max — so downstream components must survive that clamp ceiling. Peak pulse power is 1500 W, and the peak pulse current is rated at 187 A under the 8/20 µs waveform. That 187 A figure is the surge it can handle once; repetitive pulsing needs derating per the thermal curve, which the datasheet covers. Capacitance sits at 1450 pF at 1 MHz — fine for DC power rails and low-speed lines, but too high for high-speed data interfaces like USB 2.0 or Ethernet without signal degradation. ## Package and mounting — through-hole axial The 1.5KE30CARL comes in a DO-201AA / DO-27 axial-lead package, through-hole mount. The DO-201 footprint is standard for this power class — lead spacing and body diameter match the common 1.5KE family layout. No MSL concern for through-hole parts; just standard ESD handling during insertion. The axial leads suit point-to-point wiring on terminal blocks or PCB through-hole layouts, but the body is larger than an SMC or SMA surface-mount TVS, so board space is the trade-off.","metaTitle":"1.5KE30CARL TVS Diode, 1500W Bidirectional, 28.5V Breakdown","metaDescription":"STMicroelectronics 1.5KE30CARL bidirectional TVS diode, 1500W peak pulse, 28.5V min breakdown, 53.5V clamping.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"STMicroelectronics","Type":"Zener","Series":"1.5KE, TRANSIL™","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE","Operating Temperature":"-","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"1450pF @ 1MHz","Supplier Device Package":"DO-201","Voltage - Breakdown (Min)":"28.5V","Voltage - Clamping (Max) @ Ipp":"53.5V","Voltage - Reverse Standoff (Typ)":"25.6V","Current - Peak Pulse (10/1000µs)":"187A (8/20µs)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/089e26c8bbf5e28593f663899fc6cea1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5KE30CARL/alternatives.json"},"ai":{"faq":[{"question":"Is 1.5KE30CARL obsolete?","answer":"Yes, the 1.5KE30CARL is marked Obsolete by STMicroelectronics.
