Detailed Specs

The SMLJ48CA-TP is a bidirectional TVS diode with a stand-off voltage of 48V. The 'CA' suffix indicates it is bidirectional. The peak pulse power dissipation is typically rated at 3000W for a 10/1000μs 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 generally between -55°C to +150°C. It is crucial 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 will also contain information on the device's capacitance and its ability to handle repetitive surge events.
