The reverse standoff voltage of 145 V means the part will not conduct appreciably below that DC level, making it suitable for protecting 120 VAC or 145 VDC rails where the normal operating voltage stays under that threshold. Housed in a DO-201AA axial leaded package (DO-27 equivalent), the 1.5KE170C-B is a through-hole device. The axial leads require a 1.1 mm diameter hole on a 0.400-inch lead spacing — standard for this package family. Littelfuse lists the 1.5KE170C-B as Obsolete.","metaTitle":"Littelfuse 1.5KE170C-B TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE170C-B bidirectional TVS Zener diode, 1500W peak pulse, 145V standoff, DO-201AA axial.
