| Working Peak Reverse Voltage |
The 1SMC28AT3 is a unidirectional Zener transient voltage suppressor (TVS) diode from On Semiconductor, designed to protect voltage-sensitive components from high-voltage, high-energy transients. It features a working peak reverse voltage of 28V and a clamping voltage of 45.4V, with a peak pulse power rating of 1500W at 1ms. The device offers an ESD rating of Class 3 (>16 kV) per Human Body Model and a fast response time typically less than 1 ns. It is UL 497B certified for isolated loop circuit protection.
The 1SMC28AT3 is housed in a void-free, transfer-molded thermosetting plastic SMC (DO-214AB) package with modified L-bend leads for surface mount soldering. The cathode is indicated by a molded polarity notch. The case is designed for corrosion resistance and solderability, with a maximum soldering temperature of 260°C for 10 seconds. This TVS diode is suitable for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies, and other industrial/consumer applications.
