The clamping ratio of roughly 1.65× (18.2V clamp vs 11V standoff) tells you how much headroom the protected load sees during a transient — this is the figure to compare against the downstream IC's absolute maximum input rating when selecting a TVS for a given rail. ## 1500W peak pulse power and thermal margin Rated 1500W at the 10/1000µs surge waveform — that 10µs rise and 1000µs fall time is the standard IEC 61000-4-5 surge pulse shape, so the 1.5SMCJ is built for board-level surge immunity on power rails, not the faster 8/20µs lightning test. Check your system-level test standard before committing. The 150°C maximum junction temperature gives meaningful margin over the standard 125°C grade common in consumer TVS parts — in a sealed enclosure or on a warm PCB, that extra 25°C of thermal ceiling means less aggressive derating is required at the board level. ## Package and sourcing posture The DO-214AB (SMC) is the mid-size SMC package — larger than the DO-214AA (SMA) but smaller than the DO-214AC (SMB). The cathode band on the SMC body marks pin 1, so orientation is unambiguous during rework.","metaTitle":"Panjit 1.5SMCJ11A_R1_00001 TVS Diode, 11V standoff","metaDescription":"Panjit 1.5SMCJ11A unidirectional TVS diode, 11V standoff, 18.2V clamping max at 82.4A peak pulse, 1500W peak power, DO-214AB SMC.
