Detailed Specs
The SMDJ14A-T7 is a unidirectional TVS diode with a stand-off voltage of 14V. The peak pulse power dissipation is rated at 3000W for a 10/1000 μs waveform. The clamping voltage is designed to limit the voltage across the protected circuit to a safe level during a transient event. The operating temperature range is typically from -55°C to +150°C. It is important to consult the manufacturer's datasheet for precise electrical characteristics, including the clamping voltage at specific test currents, reverse leakage current, forward voltage drop, and surge current capability. The datasheet also provides information on the device's capacitance and its ability to handle repetitive surge events.
