1500 W peak pulse, DO-201 axial — the TVS for general-purpose board protection
The 1.5KE160A B0G: It clamps transients at 219 V maximum, with a 136 V reverse standoff voltage — meaning it stays off the bus under normal 136 V DC or peak AC and only conducts when the surge pushes past that threshold.
Breakdown and clamping — the numbers that decide the protection margin
Minimum breakdown voltage is 152 V, so the device guarantees avalanche conduction starts no later than that point. The clamping ceiling of 219 V at 7.1 A peak pulse current sets the maximum voltage the protected circuit sees — a downstream 250 V-rated capacitor or 200 V MOSFET would need a higher-rated TVS or a series resistor to survive the clamp. The DO-201AA axial package (also known as DO-27) is through-hole, so it handles rework with a soldering iron or hot-air station without lifting pads — the leads take the thermal stress, not the board.
