The minimum breakdown voltage is 11.75 V, so a 12 V nominal rail that sags to 11.5 V under load will not trigger the TVS into conduction — the part stays transparent until the transient pushes above that threshold. Maximum clamping at 19.11 V means downstream components rated for 20 V or higher survive the clamped surge. The 83.5 A peak pulse current (10/1000 µs) is the current the TVS shunts during that event; the upstream fuse or PTC must open before the TVS exceeds its 1500 W rating.","metaTitle":"Littelfuse 1.5SMC13C TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5SMC13C Zener TVS, 1500W peak pulse, 11.1V standoff, bidirectional, DO-214AB.
