This is a bidirectional device, so it clamps both positive and negative surges, making it suitable for AC signal lines or bipolar DC buses where polarity reversal is possible. ## DO-201 axial — through-hole board integration Housed in the DO-201AA (DO-27) axial leaded package, with the supplier device package designated DO-201. The through-hole mounting suits point-to-point wiring or PCB layouts where a leaded part provides mechanical strain relief. The Tape & Reel packaging is intended for automated insertion — verify feeder compatibility for the axial form factor. This covers industrial, automotive under-hood, and military ambient conditions — the 175°C TJ ceiling allows the device to absorb repetitive surge energy without derating the peak pulse power below the 1500W rating, provided the average power dissipation stays within the package's thermal limits. ## Not for mains — no power line protection The 1.5KE47CA-T is explicitly marked as having no power line protection. It is intended for secondary-side DC rail clamping, signal line transient suppression, or low-voltage AC signal protection — not for 120/230 VAC mains input stages. The 40.2V standoff is too low for rectified mains; use a higher-voltage TVS or MOV for that application.","metaTitle":"1.5KE47CA-T Diodes Inc TVS, 1500W, 40.2V Standoff, DO-201","metaDescription":"Obsolete 1.5KE47CA-T bidirectional TVS diode, 1500W peak pulse, 40.2V standoff, DO-201 axial.
