Product details

1.5kW clamping in a DO-201 axial package

The 1.5KE220A-G: Its 185V reverse standoff voltage and 328V maximum clamping at 4.57A peak pulse current make it a fit for protecting 185V DC rails or 130V AC lines from transient overvoltage events.

Through-hole mounting, wide thermal range

Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), it suits through-hole board assembly where the lead bend and body length must fit the existing PCB layout. The -55°C to +150°C junction temperature range covers industrial and outdoor equipment without derating concerns.
