That clamp margin — 50V on a 28V rail — gives downstream converters and ICs a survivable voltage envelope during a transient. ## Temperature range and package The unidirectional configuration protects a single polarity rail; for AC or bidirectional lines, a pair back-to-back or a dedicated bidirectional part is needed.","metaTitle":"SMBJ28E3/TR13 Microchip Zener TVS Diode 600W 28V DO-214AA","metaDescription":"SMBJ28E3/TR13 Microchip Zener TVS diode, 600W peak pulse, 28V reverse standoff, DO-214AA SMB package.
