Breakdown occurs at a minimum of 11.4V, ensuring the TVS triggers before the protected circuit's voltage tolerance is exceeded. The single bidirectional channel replaces two unidirectional diodes in series, saving board space and reducing forward voltage drop in the protection path. ## Automotive qualification and thermal envelope The DO-201AA (DO-27) axial-lead package allows through-hole mounting on power entry boards or bus bars, with the large body dissipating heat from repetitive surge events. ## Sourcing and lifecycle posture Supplied in Bulk packaging (loose in a bag or tube, not tape-and-reel), which is the correct ordering code for hand-insertion or low-volume assembly — confirm your pick-and-place setup if you need the tape-and-reel variant.","metaTitle":"1.5KE12CAHB0G TVS Diode, 1.5kW, 10.2V, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE12CAHB0G bidirectional TVS, 1500W peak pulse, 10.2V standoff, AEC-Q101 automotive grade.
