TVS diode for 300V rail protection
The 1.5KE350CA-TP: It clamps a 300V nominal rail — reverse standoff voltage is 300V, breakdown starts at 332V min, and clamping is max 482V at the peak pulse current. Bidirectional means a single device protects both polarities on the same line, useful for AC-coupled signals or floating supplies where the surge can swing either direction.
Through-hole DO-201AE — field-swappable
Housed in a DO-201AE axial-lead package, through-hole mount. No hot-air station needed — two solder points, a desoldering wick, and you are back in business. Polarity is irrelevant here since it is bidirectional; the band on the body is the cathode mark but the part works either way.
No pin-compatible successor or second-source is listed; the base number 1.5KE350 is the family identifier, and the -TP suffix denotes tape-and-reel packaging for automated insertion.
