Additional Details

The SMEJ16AG/TR7 has a standoff voltage, which represents the maximum voltage the device can withstand without conducting. The clamping voltage is the voltage to which the device clamps during a surge event, protecting the downstream circuitry. It is rated for peak pulse power dissipation and surge current. The operating temperature range typically spans from -55°C to +150°C. Refer to the manufacturer's datasheet for specific electrical characteristics, surge handling capabilities, and other performance parameters.
