The single bidirectional channel means one device protects both polarities on the same line. ## Automotive-grade transient protection The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles. Power line protection is not intended here (the part is marked 'No' for that), so use it on signal or low-power supply rails.","metaTitle":"1.5KE51CAHA0G TVS Diode, 1.5kW, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE51CAHA0G bidirectional TVS, 1500W peak pulse, 43.6V standoff, AEC-Q101 qualified, DO-201 axial.
