The operating junction temperature range spans -55°C to +175°C. The wide temperature grade suits environments where the TVS sees self-heating from repetitive surges — the 175°C TJ max provides margin above the 150°C typical for many industrial TVS parts.","metaTitle":"1.5KE480A-E3/51 Vishay TVS, 1.5kW, 408V Standoff","metaDescription":"Vishay 1.5KE480A-E3/51 TransZorb® TVS, 1500W peak pulse, 408V standoff, DO-201AA.
