A 124A event at 12.1V represents roughly 1.5 kJ of energy in a 1 ms pulse — the kind of spike that kills gate oxides and latch-up destroys bus receivers if not clamped fast. The 1500W figure is the product family's thermal reference, not a continuous rating. ## Standoff, breakdown, clamping — the voltage stack The standoff voltage is 7.02V typical — the device sits idle below this in normal operation, drawing only leakage current. Breakdown occurs at 7.79V minimum; the clamping voltage ceiling is 12.1V at rated peak current. That means the device transitions from off-state to conduction over a window of less than 5V, clamping at 12.1V — a 55% over-breakdown ratio. For a board protecting a 5V rail, that 12.1V ceiling sits above the rail but well below what most CMOS input stages tolerate as a damage threshold. ## Harsh-environment temperature rating The 150°C ceiling gives margin for the thermal rise during a clamp event — the clamping voltage will track upward with junction temperature, so the 12.1V spec is the 25°C baseline. DO-214AB (SMC) package is the standard surface-mount form factor for this power class, accepting standard reflow profiles and compatible with standard copper pad layouts for the series.","metaTitle":"Vishay 1.5SMC8.2CA-E3/9AT TVS Diode, 1500W Peak","metaDescription":"1.5SMC8.2CA-E3/9AT — Vishay TransZorb bidirectional TVS Zener, 7.02V standoff, 7.79V min breakdown, 1500W peak, DO-214AB SMC.
