With a −50 to +150 °C junction operating range, it covers industrial ambient bands without derating on the transient energy side, though layout pad size and copper area under the cathode tab govern the actual thermal resistance junction-to-ambient. General-purpose classification covers a wide deployment window — signal lines, control bus protection, and low-current power rails in instrumentation, drives, and industrial I/O modules are typical board-level positions. Sourced to order against BOM quantity; availability and current lead time confirmed at RFQ through independent distribution channels.","metaTitle":"Diotec 1.5SMCJ40CA TVS Diode, 40V, 1.5 kW, DO-214AB","metaDescription":"Diotec 1.5SMCJ40CA bidirectional TVS diode, 40V standoff, 1.5 kW peak pulse, 64.5V clamping, DO-214AB SMC.
