The 1.5KE8.2A R0G: Reverse standoff voltage is 7.02 V typical — the diode draws negligible leakage below this level, so it stays out of the circuit during normal operation. Breakdown voltage range (7.79 V min) ensures the diode starts conducting before the protected rail exceeds the safe operating area of downstream components.
Package and rework consideration
Through-hole DO-201AA / DO-27 axial package — the leads are robust enough for hand-soldering or wave-solder, and the body markings are clear enough to read orientation after assembly.
