The 53.3 V clamp at rated current is the number that matters for downstream device survival — if the protected rail's absolute maximum rating is below that voltage, the TVS will not hold the transient within the safe operating area. General-purpose application means no internal power-line protection filter; this is a bare clamping diode intended for signal, data, or low-power DC bus protection. ## Package and temperature — board-fit and deployment range The junction temperature range spans -55°C to 150°C, covering both outdoor telecom cabinets and under-hood automotive ambient without derating at the high end. No power-line protection feature is claimed — the diode is a straight clamping element, so the board layout must keep the TVS close to the protected IC and minimise loop inductance between the TVS and the rail. ## Active production — no lifecycle risk for new BOMs Bourns lists the 1.5SMBJ33A as Active in production.","metaTitle":"Bourns 1.5SMBJ33A TVS Diode, 1500W, 33V, DO-214AA","metaDescription":"Bourns 1.5SMBJ33A Zener TVS, 1500W peak pulse power, 33V reverse standoff, 53.3V clamping at 28.2A.
