The 48V reverse standoff voltage sets the maximum continuous DC operating level before the diode begins to conduct — a 48V rail with 10% tolerance stays below the 53.3V minimum breakdown voltage. ## Junction temperature envelope and package Operating junction temperature spans -65°C to 150°C — wide enough for outdoor telecom cabinets, industrial motor drives, and underhood automotive electronics. ## Active production — sourcing posture","metaTitle":"SMAJ48CE3/TR13 TVS Diode – 48V Bidirectional Zener, 500W","metaDescription":"Microchip SMAJ48CE3/TR13: 48V reverse standoff, bidirectional Zener TVS, 500W peak pulse power, DO-214AC.
