The scorch mark on a dead board often traces back to a TVS that took one surge too many; this one is rated to take the hit and keep the downstream ICs alive. Housed in a DO-214AB (SMC) surface-mount package, the 1.5SMC13CA mounts directly to the PCB copper pad — the junction-to-ambient thermal path relies on the pad area, so a solid copper pour under the cathode tab pulls heat out of the die during repetitive surges. The operating temperature range spans -55°C to 150°C (junction), which covers the full industrial temp band and then some — a board sitting in an outdoor enclosure or near a hot power supply still has margin before derating kicks in. Power line protection is listed as 'No', meaning this part is not optimized for AC mains transients — it belongs on a DC rail or signal line where the 11.1V standoff matches the normal operating voltage.","metaTitle":"Littelfuse 1.5SMC13CA TVS Diode, 1500W, 18.2V Clamp","metaDescription":"Littelfuse 1.5SMC13CA bidirectional Zener TVS, 1500W peak pulse power, 18.2V clamping, DO-214AB.
