It fits standard 0.100-inch pitch holes and can be hand-soldered or wave-soldered. No special ESD handling beyond the usual wrist strap; the axial body is easy to orient with the cathode band (though bidirectional means polarity doesn't matter for the clamping direction). Supplied in tape-and-reel for automated insertion, but the through-hole form factor also makes it a field-swap candidate — a technician can pull the old one and solder in a replacement with a standard iron in under a minute. Verify the breakdown and clamping voltage match your surge requirement before substituting.","metaTitle":"1.5KE33CAH TVS Diode, 1500W, 28.2V, Automotive AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE33CAH bidirectional Zener TVS, 1500W peak pulse, 28.2V standoff, AEC-Q101.
