It clamps transients to 50V maximum at 30A peak pulse current, making it a solid choice for protecting 24V DC rails in industrial control, telecom, and general-purpose power supplies. The 50V clamping voltage at 30A peak pulse current (10/1000µs) defines the maximum voltage the downstream circuitry will see during a surge event. For a 24V nominal rail, this leaves a 26V margin above the standoff — enough headroom for most DC/DC converters and linear regulators rated at 60V input. The 1500W peak pulse rating is tested with a 10/1000µs waveform, the standard for telecom surge testing (ITU-T K.20/K.21). If your application uses a shorter pulse (e.g., 8/20µs for IEC 61000-4-5), the effective peak power derates upward — the silicon can handle more energy in a shorter burst. ## Package and Mounting – DO-214AB (SMC) The operating temperature range spans -65°C to 150°C junction, suitable for outdoor and industrial enclosures where ambient temperatures can reach 85°C.","metaTitle":"SMCJ28E3/TR13 TVS Diode – 1500W, 28V Standoff, DO-214AB","metaDescription":"Microchip SMCJ28E3/TR13 Zener TVS: 1500W peak pulse, 28V reverse standoff, unidirectional, DO-214AB.
