1.5 kW clamp in a DO-201 axial body
The 1.5KE62A B0G: It clamps at 85 V maximum with a peak pulse current of 18 A, protecting downstream circuitry from transients on a 53 V reverse standoff rail. Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), it suits through-hole mounting on boards where a single axial TVS provides bulk transient energy absorption without the footprint constraints of a surface-mount part.
Clamping voltage and breakdown margin
Breakdown occurs between 58.9 V (minimum) and the clamping ceiling of 85 V at 18 A, giving a 26 V window from the 53 V standoff rating. The 18 A peak pulse current at 10/1000 µs defines the surge capacity — a 1.5 kW device absorbing a transient that exceeds this current level will fail to clamp, so the upstream fuse or PTC must coordinate. Power line protection is not specified — this is a signal-rail or low-voltage DC bus protector, not a mains-side suppressor.
