TVS diode for 100V rail protection
The SMBJ100A-13-F is a 600 W peak pulse power Zener TVS diode from Diodes Incorporated's SMBJ series, designed to clamp overvoltage transients on a 100 V nominal rail.
What the ratings mean for the BOM
The unidirectional channel (single TVS) is polarity-sensitive: it clamps positive transients above breakdown and conducts forward like a diode on negative spikes — for AC or bidirectional lines, two back-to-back devices or a bidirectional part would be needed.
