The 85.5V clamping voltage at 5.8A peak pulse current limits the voltage seen by downstream circuitry during a surge — a key parameter for selecting the TVS against the protected IC's absolute maximum rating. ## Temperature range and surge capability Operating junction temperature spans -65°C to 150°C, covering automotive underhood, outdoor telecom cabinets, and industrial enclosures where ambient temperatures can exceed 85°C. The wide range also allows derating for high-power pulses without immediate thermal shutdown.","metaTitle":"SMAJ48E3/TR13 Zener TVS Diode – 48V, 500W, DO-214AC","metaDescription":"SMAJ48E3/TR13 Zener TVS, 48V reverse standoff, 500W peak pulse, DO-214AC (SMA).
