The 14 V reverse standoff voltage is the maximum continuous DC voltage the device can block without conducting — this matches a standard 12 V automotive battery bus or a 14 V regulated supply. When the line voltage exceeds 15.6 V, the TVS enters avalanche breakdown and begins clamping. This is a unidirectional device — it clamps only in one polarity. For bidirectional protection on AC or bipolar rails, two devices in anti-series or a dedicated bidirectional TVS is required. The device is not rated for power line protection, meaning it is intended for signal and DC power bus transient suppression, not for AC mains primary protection.","metaTitle":"SMCJ14A-13 Diodes Inc TVS, 1.5kW, 14V Standoff, DO-214AB","metaDescription":"SMCJ14A-13 Zener TVS diode, 1500W peak pulse power, 14V reverse standoff, 23.2V clamp at 64.7A.
