The junction temperature range spans -55 °C to 175 °C, covering industrial and automotive under-hood thermal profiles without derating the peak power.","metaTitle":"1.5KE9.1A A0G TVS Diode, 1.5kW, 7.78V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE9.1A A0G Zener TVS diode, 1500W peak pulse power, 7.78V reverse standoff, 117A Ipp. Active production.
