It is a bidirectional Zener-type TVS, meaning a single device clamps both positive and negative transients — useful on AC-coupled lines or where polarity is not fixed. ## Automotive-grade transient protection — AEC-Q101 qualified This part is part of Vishay's Automotive, AEC-Q101, 1.5SMC, TransZorb® series. The AEC-Q101 qualification means it has passed the automotive-grade stress tests: temperature cycling, high-temperature reverse bias, and ESD robustness per the AEC-Q101 standard. The 1500 W peak pulse power rating (1.5 kW) at 10/1000 µs is the headline number, but the real-world derating depends on pulse width and ambient temperature. For shorter pulses (e.g., 8/20 µs) the peak current capability is higher; for repetitive events, the average power dissipation must stay within the package's thermal limits. The device does not include power line protection — it is designed for signal and low-power supply rails.","metaTitle":"Vishay 1.5SMC33CAHE3/57T TVS Diode, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC33CAHE3/57T bidirectional TVS diode, 1500W peak pulse, 28.2V standoff, AEC-Q101 automotive grade.
