1500 W peak pulse in a DO-201 barrel
The 1.5KE200A/B: The 274 V clamping voltage at 5.5 A peak pulse current means a 171 V nominal rail sees the transient clipped before it stresses downstream silicon — the 190 V minimum breakdown gives margin above the standoff. Housed in a DO-201AA (DO-27) axial leaded package, the through-hole body suits point-to-point wiring or PCB mounting where the lead bend radius is controlled. The -55°C to 150°C junction temperature range covers industrial and telecom environments without derating at the hot end.
