It clamps a 24V nominal rail at 43V max when hit with a 34.9A surge, making it a fit for protecting DC power inputs, industrial controls, and telecom equipment where a single transient can kill a downstream regulator. ## Clamping window and breakdown margin The reverse standoff voltage is 24V (typical), with a minimum breakdown of 26.7V. That 19V window between standoff and clamp gives a 24V rail enough headroom to ride through transients without the diode conducting during normal ripple. ## Active lifecycle and package availability The base product number is SMCJ24, with the suffix indicating the lead-free / RoHS-compliant finish.","metaTitle":"SMCJ24E3/TR13 TVS Diode – 1500W, 24V, Unidirectional","metaDescription":"Microchip SMCJ24E3/TR13 Zener TVS diode: 1500W peak pulse power, 24V standoff, unidirectional, DO-214AB SMC package.
