The 1.5KE7.5A B0G: The 11.3V clamp is the hard ceiling — any transient that would push the protected node above that is shunted through the junction. For a 5V rail with 10% tolerance (5.5V max), the 6.4V standoff gives 0.9V of headroom before the diode starts leaking appreciably; the 11.3V clamp means downstream components must survive that peak during the event. Unidirectional (single-channel Zener), so it clamps positive transients relative to ground — not intended for AC power-line protection (the 'Power Line Protection' flag is 'No').
Through-hole mounting in a DO-201AA / DO-27 axial package (supplier device package DO-201). The leads are formed for through-hole insertion — no reflow profile needed, but the lead bend radius matters for stress relief in high-vibration environments. The 1500W rating is derated linearly above 25°C; at 175°C junction the peak pulse power capability drops to near zero — the derating curve in the datasheet governs the actual margin at elevated ambient.
Active production — no lifecycle surprises on this BOM line
Listed as Active with no NRND or EOL flag from Taiwan Semiconductor. The bulk packaging (B0G suffix) indicates a standard bulk tube or bag — no reel or tape-and-reel.
