The DO-201AA axial footprint is common across the 1.5KE series, so a parametric cross to another 1500 W bidirectional 300 V standoff TVS in the same package is possible, but the replacement part number must be verified against the BOM's clamping and breakdown tolerance. ## DO-201AA axial package and temperature range Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE350CA-/73 mounts through-hole on a PCB or terminal block. The junction temperature range spans -55°C to 175°C, covering industrial and telecom environments where the ambient sees wide thermal cycling. No power line protection feature is built in — this is a standalone transient clamp for signal or DC bus rails, not a mains-rated protector.","metaTitle":"1.5KE350CA-E3/73 Vishay TVS, 1500W, 300V Standoff, DO-27","metaDescription":"Obsolete Vishay 1.5KE350CA-E3/73 TransZorb bidirectional Zener TVS, 1500W peak pulse, 300V standoff, DO-201AA axial.
