1500W Zener TVS for 7V rail protection
The SMCJ7.0AE3/TR13 is a unidirectional Zener TVS diode rated for 1500W peak pulse power (10/1000µs waveform), with a 7V reverse standoff voltage and a 12V clamping point at 125A peak pulse current.
Voltage window and surge capability
The breakdown voltage range starts at 7.78V minimum, giving a 0.78V margin above the 7V standoff before the device begins to conduct. The clamping voltage of 12V at 125A peak pulse current sets the maximum voltage the protected circuit sees during a surge event — a 5V rail with a 12V clamp leaves 7V of headroom, which is typical for TVS-protected low-voltage supplies. The 1500W peak pulse rating at 10/1000µs waveform means this part handles industrial-grade transients like lightning-induced surges or inductive load dumps.
Housed in the DO-214AB (SMC) package, the SMCJ7.0AE3/TR13 is a surface-mount device with a standard footprint shared across the SMCJ series. The package body is rated for the full 1500W dissipation when the PCB copper area meets the datasheet layout recommendation.
