6V rail guard in a DO-214AC body
It is a general-purpose protection device, surface-mount in the DO-214AC (SMA) package, and ships on Tape & Reel. With a reverse standoff voltage of 6V and a minimum breakdown of 6.67V, it sits right at the threshold where a 5V logic rail or a 6V bias line needs a hard clamp before the downstream IC's absolute maximum is reached.
Clamping voltage and peak current – the real protection envelope
When a transient hits, the diode clamps at 10.3V maximum while shunting 48.5A of peak pulse current (10/1000 µs waveform). That 10.3V ceiling is the number to compare against the downstream component's breakdown rating — if the protected IC can survive 12V, this TVS buys margin. Peak pulse power is rated at 500W for the same 10/1000 µs pulse. This is the energy-handling headline; for shorter pulses (8/20 µs) the effective power rating is higher, but the datasheet's derating curve is the tool for that calculation.
