The 1500 W peak pulse rating positions this part in the mid-range of the 1.5SMCJ series — enough for secondary protection on data lines and low-power control rails, not a primary bus protector on a 100 A supply. ## Package and board-level fit The SMC/DO-214AB package is the standard large-body SMA variant — the wider leadframe than a plain SMA gives better thermal path to the board pad. Surface-mount termination means reflow assembly is the primary flow; confirm the landing pattern matches the SMC footprint and that the cathode bar marks the polarity direction before reflow — on a unidirectional TVS the polarity is not reversible without circuit consequence. ## Sourcing and lifecycle posture The part is confirmed active under the Diotec Semiconductor brand.","metaTitle":"1.5SMCJ22CA Diotec TVS Diode, 22V Standoff, 1.5 kW","metaDescription":"1.5SMCJ22CA by Diotec Semiconductor — unidirectional TVS diode, 22V standoff, 24.4V min breakdown, 35.5V clamping, 1500W peak pulse.
