Clamping voltage and pulse handling for the 1.5KE120A B0G
The 102V standoff makes this part a fit for 48V telecom rails, 72V battery buses, and 120VAC equipment where the nominal line voltage stays below the standoff threshold. The 165V clamp ceiling means downstream components rated for 200V or higher see a safe voltage during a surge event.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120A B0G is a through-hole device intended for point-to-point wiring or PCB mounting with lead forming. The DO-201 body handles the thermal pulse of a 1500W surge without requiring a heatsink, relying on the lead-frame and solder joints to conduct heat into the board copper. The wide range also supports applications that see cold starts or high-temperature soak-back.
The bulk packaging suits high-volume assembly or bench stock for repair and prototyping.
