The 33.3 V reverse standoff voltage is the continuous DC or peak AC voltage the diode can block without conducting; the line it guards must stay below this under normal operation. The operating temperature range of -55°C to 150°C covers the full industrial and telecom enclosure ambient, including the self-heating from repetitive surges. The SMC body handles the 1500 W pulse without cracking the epoxy — the copper leadframe and die attach are sized for the thermal shock of a 10/1000 µs transient. The tape-and-reel packaging (TR) suits automated pick-and-place; the reel quantity is confirmed at RFQ.","metaTitle":"1.5SMC39A V7G TVS Diode, 1500W, 33.3V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC39A V7G Zener TVS, 1500W peak pulse, 33.3V reverse standoff, 29A Ipp, DO-214AB.
