Product details

1500W bidirectional Zener TVS in DO-201 axial

The 1.5KE100CA-B: The bidirectional configuration (single channel) protects against both positive and negative transients without needing to orient the part on the board.

DO-201 axial package — rework and board fit

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE100CA-B is a through-hole part. The bulk packaging means it ships loose in a bag or tube — no tape-and-reel, so plan for manual insertion or vibratory bowl feed if you're automating the line.

Obsolete — sourcing through independent channels

Diodes Incorporated lists the 1.5KE100CA-B as obsolete. The base product number is 1.5KE100, so any variant with a different suffix (e.g., 1.5KE100A for unidirectional) shares the same die and package but changes the polarity. If your design can accept a unidirectional clamp, that may open more sourcing options.
