Zener TVS for 100V rail protection
Its 162V clamping voltage at 3.7A peak pulse current (10/1000µs waveform) defines the maximum voltage a protected load sees during a surge event.
Active production and ordering path
Microchip lists the SMBJ100CAE3/TR13 as Active.
Junction temperature range is -65°C to 150°C. That covers military and industrial extremes — the part will function in an outdoor telecom cabinet or an engine-bay ECU without derating the peak pulse power at the cold end. At the hot end, the 600W rating assumes a 25°C ambient; above 25°C, derate the peak pulse power per the datasheet curve to avoid thermal runaway during repetitive surges.
