The breakdown voltage window starts at 136 V min, so the device begins to avalanche before the rail exceeds that threshold. This 121 V standoff / 136 V breakdown / 215 V clamp stack defines the protection envelope for a 100–120 V DC bus or a 85–130 V AC line that needs bidirectional clamping — the single bidirectional channel handles both polarities in one package. ## Through-hole DO-201AA axial — board-level mounting Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE150C-/73 mounts through-hole on a PCB or terminal strip. The axial body allows either vertical or horizontal placement depending on board clearance — the leads are tin-plated copper for solderability into standard 1.0 mm diameter plated holes. The wide junction temperature range means the leakage current at the standoff voltage stays within spec across the full thermal envelope.","metaTitle":"Vishay 1.5KE150C-E3/73 TransZorb TVS, 1500W, 121V Standoff","metaDescription":"Obsolete Vishay 1.5KE150C-E3/73 TransZorb bidirectional TVS diode, 1500W peak pulse, 121V reverse standoff, DO-201AA axial.
