Those three numbers define the protection window for the downstream circuitry. Raise the pulse width or energy content and the clamping voltage climbs above that 121 V figure; the datasheet curves show the derating. ## DO-214AB SMC footprint — pad layout and thermal housekeeping The DO-214AB (SMC) package is the workhorse body for 1.5–3 kW TVS diodes. Diotec lists the mounting type as surface mount and the supplier package as SMC/DO-214AB, so reflow assembly follows standard lead-free profile. No exposed paddle is specified, so thermal resistance is governed by the tab-to-board interface rather than a dedicated heat slug. The package ships as strip packaging per the listing, which is typical for reel-feeder assembly but does not carry a moisture sensitivity level in this spec block — if the production line runs a bake-before-assembly protocol, verify the MSL with Diotec before committing a high-temperature profile.","metaTitle":"Diotec 1.5SMCJ75CA TVS Diode, 75V Standoff, 1.5 kW","metaDescription":"1.5SMCJ75CA — Diotec bidirectional TVS diode, 75V standoff, 83.3V breakdown, 121V clamping, 12.4A peak pulse.
