For a 17.1 V rail, this clamp margin of about 10 V above the operating voltage means the downstream components must withstand that peak — typical 20 V-rated parts on a 17.1 V rail have headroom, but 16 V-rated parts do not. In real-world transients shorter than 1 ms, the device absorbs more peak power; for longer events, derate per the pulse-width curve in the datasheet. The -55°C to 150°C junction temperature range covers both cold-start and hot ambient conditions in outdoor or industrial gear.","metaTitle":"Littelfuse 1.5SMC20CA TVS Diode, 1500W, 27.7V Clamp","metaDescription":"Littelfuse 1.5SMC20CA bidirectional Zener TVS, 1500W peak pulse, 27.7V clamping, DO-214AB.
