110V rail protection in a standard SMA footprint
The SMAJ110A-13: Its 122V minimum breakdown voltage and 177V maximum clamping at 2.3A peak pulse current define the protection envelope for a single line in a general-purpose circuit protection application.
What the clamping voltage means for your protected circuit
When a transient exceeds the 122V breakdown threshold, the device avalanches and clamps the voltage to 177V maximum at the rated 2.3A peak pulse current. The 400W peak pulse power rating is the energy-handling limit for the standard 10/1000µs waveform — a shorter pulse allows a higher peak current, but the clamping voltage stays at 177V. The -55°C to 150°C junction temperature range covers most industrial and telecom ambient conditions without derating concerns. The DO-214AC SMA package is a common surface-mount footprint for TVS diodes, compatible with standard reflow profiles and pick-and-place assembly.
