That clamping voltage is the ceiling the downstream circuitry must survive. The -65°C to 150°C junction temperature range covers industrial and military thermal environments without derating the peak pulse power — a common requirement for outdoor telecom or avionics power supplies.","metaTitle":"SMAJ28CE3/TR13 Microchip 28V Bidirectional TVS Diode, 500W","metaDescription":"Microchip SMAJ28CE3/TR13 Zener TVS diode, 28V reverse standoff, 500W peak pulse, bidirectional, DO-214AC (SMA).
