The bidirectional configuration (single channel) protects lines that swing both positive and negative relative to ground, such as AC signal pairs or differential data lines. ## Obsolete — sourcing the 1.5KE75C today Littelfuse has marked the 1.5KE75C as Obsolete. The part is available through independent surplus and broker channels — each lot is date-code and quantity verified at the time of the RFQ. Confirm the required quantity and date-code window when requesting a quote. ## DO-201 axial package and temperature range Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE75C mounts with the body off the board — the leads absorb thermal expansion and vibration. The junction temperature range spans -55°C to +175°C, covering industrial and some automotive under-hood environments.","metaTitle":"Littelfuse 1.5KE75C TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Littelfuse 1.5KE75C bidirectional TVS, 1500W peak pulse, 64.1V standoff, 108.15V clamp.
