The reverse standoff voltage (8.5V) is the maximum continuous DC voltage the diode can withstand without conducting — your supply rail must stay at or below this level. That 14.4V ceiling is what the downstream IC sees; it must survive that peak without damage. ## Package and board integration Housed in the DO-214AC (SMA) package, this is a surface-mount device with a low-profile footprint suited for automated assembly. The wide temperature span means the clamping voltage and leakage current shift predictably across the range — the datasheet's typical curves show the breakdown voltage increases slightly at cold and decreases at hot, but the clamping ceiling stays within the specified max. ## Active lifecycle and sourcing posture No stock-holding claim — each RFQ is handled on its own terms.","metaTitle":"SMAJ8.5A-13 Diodes Inc TVS Diode, 400W, 8.5V, DO-214AC","metaDescription":"SMAJ8.5A-13 400W unidirectional TVS diode, 8.5V reverse standoff, 27.7A peak pulse.
