Breakdown triggers at a minimum of 83.3V and the clamping ceiling sits at 121V — at the 41.4A peak pulse condition — which means the diode intercepts a surge and clamps the protected node well below the withstand voltage of most downstream telecom PHY interfaces. The CA suffix denotes the bidirectional variant; the symmetric bidirectional breakdown characteristic makes this the correct choice for protecting differential signal pairs and tip-and-ring telecom interfaces where neither side references a reliable ground. ## Junction temperature and board-fit for outdoor telecom enclosures The DO-214AB (SMC) package mounts on the board surface with a soldered thermal pad under the cathode tab; the board-level thermal resistance from junction to ambient determines the continuous dissipation ceiling under surge — not the peak 5kW transient rating, which is a single-event pulse condition. ## Active production — Bourns as manufacturer Listed as Active by Bourns — this part is in normal production and not under an NRND or EOL notification as of the current ledger entry. Confirm Bourns availability at RFQ before committing to single-source BOM positions.","metaTitle":"Bourns 5.0SMDJ75CA-H SMC TVS Diode, 75V / 5kW Bidirectional","metaDescription":"Bourns 5.0SMDJ75CA-H bidirectional TVS diode, 75V standoff, 5kW peak pulse, DO-214AB (SMC).
