TVS diode for 110V rail protection
Its 110V reverse standoff voltage means it sits across the line without conducting under normal operation, then avalanches at a minimum of 122V to shunt surge energy. The 177V maximum clamping voltage at 2.8A peak pulse current limits the voltage spike seen by downstream components — a key check against the protected circuit's absolute maximum rating.
Peak pulse power and surge capability
The 2.8A peak pulse current at the clamping voltage gives a direct check against the expected surge current from a lightning surge or inductive kickback — if the transient exceeds 2.8A, a higher-power TVS or external series impedance is needed.
The DO-214AC (SMA) surface-mount package mates with standard reflow profiles and is compatible with automated assembly lines. The bidirectional configuration simplifies layout — no polarity concern when protecting AC lines or bipolar DC rails.
