The standoff voltage is 17 V nominal, breakdown minimum is 18.9 V, and the clamping voltage at peak pulse current is 30.5 V. During a transient event the diode switches from high-impedance to a low-impedance clamp in nanoseconds, holding the downstream circuit at or below 30.5 V regardless of the applied surge magnitude. Peak pulse current is 49.2 A at the 10/1000 µs wave shape. This is the current the part survives when the clamping voltage is at its maximum — the actual let-through current into the protected load is held at the clamped level, not the full surge amplitude. ## DO-214AB SMC package — surface-mount transient protection It mates with the standard land pattern on most power-management boards; the Cathridge bar on the package marks the polarity (cathode). One unidirectional channel handles the asymmetric clamping needed on DC power lines. Junction temperature range is -50°C to 150°C. The upper limit constrains how much self-heating the part tolerates under repeated transients — above 150°C TJ the leakage and breakdown characteristics shift, so the board-level thermal path matters in high-cycle surge environments.","metaTitle":"Diotec 1.5SMCJ17 TVS Diode, 1.5kW, 30.5V Clamping","metaDescription":"Diotec unidirectional TVS diode, 1.5 kW peak pulse, 17 V standoff / 18.9 V breakdown, DO-214AB SMC surface-mount.
