Clamping is specified at 245.7 V maximum at a peak pulse current of 6.5 A. Littelfuse lists the 1.5KE170C as obsolete. No official successor part number is recorded on this line — the 1.5KE series was a broad axial family and replacement parts are not pin-to-pin drop-ins without checking the full TVS parametric (standoff, breakdown, clamping, package). ## Package and temperature envelope Housed in a DO-201AA (DO-27) axial-lead package, through-hole mounted — the same footprint used across the 1.5KE family. The junction temperature range spans -55°C to +175°C, covering industrial and some military/aerospace ambient conditions without derating for cold starts. Single bidirectional channel means the device protects both polarities of a transient — useful on AC signal lines or bipolar DC rails where two unidirectional parts in anti-series would otherwise be needed.","metaTitle":"1.5KE170C Littelfuse TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE170C bidirectional TVS diode, 1500W peak pulse power, 145V standoff, DO-201 package.
