Minimum breakdown is 122 V at 25 °C junction, which means the gap between 110 V standoff and 122 V breakdown is a 12 V window — any transient that reaches 122 V triggers the clamp and forces the device into low-impedance avalanche. The unidirectional, single-channel architecture means it protects one polarity only: positive transients relative to ground. For a bidirectionalabus, a two-device stack or a separate part would be needed. Power line protection is listed as No — this is not a mains-suppressor TVS; it is a board-level transient suppressor sized for secondary-side protection in telecom, industrial control, or consumer electronics where the protected rail sits below 110 V DC. Designers should verify the clamping voltage does not exceed the absolute-max rating of the downstream IC under the specific surge waveform present in the end application. ## Operating temperature and thermal margin The junction temperature range is -50 °C to 150 °C — the lower bound covers outdoor and cold-start conditions, and the upper bound is the maximum junction the die sees during a clamping event. For a 1500 W rated device in SMC package, thermal management during a surge is dominated by the lead-frame solder joint and the PCB copper area under the cathode tab; a minimum recommended land pattern should be confirmed from the Diotec datasheet thermal pad layout. The supplier device package field confirms the Diotec naming maps directly to the SMC/DO-214AB footprint.","metaTitle":"Diotec 1.5SMCJ110 TVS Diode, 1500W, 196V Clamp","metaDescription":"Diotec 1.5SMCJ110 unidirectional TVS diode, 1500W peak pulse, 196V clamping, DO-214AB SMC package.
