That clamping voltage is what the protected downstream circuitry actually sees — it is the number the system architect uses to verify the downstream component absolute-maximum rating has margin. ## Junction temperature and the telecom deployment envelope Telecom equipment frequently lives in heated shelters or exposed outdoor cabinets, so this range covers both extremes without derating the part for the application. The 5.0SMDJ series is listed for telecom applications specifically, where lightning-induced surge immunity is a front-end compliance requirement.","metaTitle":"Bourns 5.0SMDJ9.0CA TVS Diode, 5000W Peak, 9V Standoff","metaDescription":"Bourns 5.0SMDJ9.0CA is a bidirectional TVS Zener in DO-214AB (SMC), 9V standoff, 15.4V clamping, 5000W peak pulse.
