7V rail clamp with 600W surge rating
It is specified for a peak pulse power of 600W (10/1000µs waveform) and a clamping voltage of 13.3V at the peak pulse current of 45.1A. The 7V reverse standoff voltage (VRWM) means this part sits across a 5V or 6V supply bus without conducting in steady state, then fires at a minimum breakdown of 7.78V to shunt the surge away from the load.
Active production, DO-214AA package
Microchip lists the SMBJ7.0E3/TR13 as Active.
The operating junction temperature range spans -65°C to 150°C, covering military, aerospace, and industrial environments where the ambient can dip below -40°C or rise above 85°C. The 600W peak pulse rating at 25°C derates with temperature — at 150°C the power capability drops, so the designer should check the derating curve in the datasheet for the actual margin at the worst-case ambient.
