The reverse standoff voltage is 17.1V, so it sits across a 12V or 15V rail without conducting in normal operation, and breakdown is guaranteed between 19V and the clamping ceiling. Bidirectional means one part covers positive and negative transients — handy when the line polarity isn't fixed or you want to simplify the BOM. ## What the ratings mean for your protection design For shorter pulses (like 8/20µs) the peak power capability is higher, but the datasheet's 10/1000µs rating is the conservative number to use for BOM margin. The DO-201 axial package (also known as DO-27) is through-hole — easy to hand-solder or wave-solder, and the leads are thick enough to handle the pulse current without fusing. Note that power line protection is listed as 'No' — this TVS is intended for secondary-side or signal-line clamping, not for direct mains surge suppression. For AC mains you would look at a higher-energy MOV or a dedicated power TVS rated for repetitive surges. ## Active lifecycle and sourcing posture Sourced to order against your BOM quantity through independent and authorized distribution.","metaTitle":"1.5KE20CA A0G Taiwan Semiconductor TVS Diode, 1500W","metaDescription":"Active 1.5KE20CA A0G bidirectional TVS diode from Taiwan Semiconductor. 1500W peak pulse power, 17.1V standoff, DO-201 package.
