Product details

1500W peak pulse in a DO-201 axial body

The 1.5KE170: Its 145V reverse standoff voltage means the protected rail can run at 145V DC without the diode conducting leakage; clamping starts at 153.45V minimum breakdown and limits transients to 245.7V maximum at the 6.5A peak pulse current.

Obsolete — sourcing through independent channels

Littelfuse lists the 1.5KE170 as obsolete. Available through independent surplus and broker inventory — quantities and pricing confirmed at RFQ.

DO-201 axial package and temperature range

Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), rated for through-hole mounting. Tape and Reel packaging available.
