Operating temperature spans -65°C to 150°C (junction), covering the full industrial and automotive ambient range. The DO-214AB (SMC) package is a standard surface-mount footprint shared with many SMCJ-series parts, so PCB layout reuse across multiple voltage variants is straightforward. No power line protection — the device is intended for secondary-side transient suppression on data, signal, or low-voltage power buses, not for direct mains AC line clamping. ## Active lifecycle and sourcing posture For BOM planning, the base product number is 1.5SMC170, and the full ordering code must include the suffix to match the reel and finish requirement.","metaTitle":"Vishay 1.5SMC170CA-E3/9AT TVS Diode, 1500W, 234V Clamp","metaDescription":"Vishay 1.5SMC170CA-E3/9AT bidirectional TVS diode, 1500W peak pulse power, 234V clamping, DO-214AB.
