It clamps transients at 45.7 V maximum while standing off 25.1 V continuous, making it a fit for 24 V rails that need protection against load-dump or surge events. The SQ-MELF C package is a surface-mount ceramic body with metallized end caps, designed for reflow assembly and good thermal transfer to the board. The 31.4 V minimum breakdown voltage sets the threshold where the diode starts conducting — below that the rail sees no leakage. The 45.7 V clamping voltage is the maximum voltage the protected circuit sees during a 32.8 A peak pulse current. Operating junction temperature from -55°C to 175°C covers cold-crank and under-hood conditions. The 1.5 kW rating holds at 25°C; derate per the datasheet curve above that temperature. ## Lifecycle and sourcing posture Sourced per RFQ — confirm current pricing and availability at quote time.","metaTitle":"1N6154US/TR Zener TVS Diode – 1.5 kW, SQ-MELF, Active","metaDescription":"1N6154US/TR from Microchip Technology: Zener TVS diode, 1.5 kW peak pulse power, 25.1 V standoff, 45.7 V clamping, SQ-MELF package.
