The 1SMA70AT3G is a 400W peak power unidirectional transient voltage suppressor (TVS) diode from ON Semiconductor, part of the 1SMA5.0AT3 series. It is designed to protect voltage-sensitive components from high-voltage, high-energy transients. Key electrical specifications include a working peak reverse voltage of 70V, a clamping voltage of 113V at a peak pulse current of 3.5A, and a peak pulse power rating of 400W for a 1ms pulse. The device features a fast response time typically less than 1 ns and an ESD rating of Class 3 (>16 kV) per the Human Body Model.
The diode is housed in a surface-mount SMA (DO-214AC) package, which offers a low profile and flat handling surface for accurate placement. It supports an operating temperature range of -65°C to 150°C and is suitable for soldering at up to 260°C for 10 seconds. The package is void-free, transfer-molded plastic with corrosion-resistant leads. The device is supplied in tape and reel packaging with a standard quantity of 5000 pieces.
Typical applications include communication systems, automotive electronics, numerical controls, process controls, medical equipment, business machines, and power supplies. The 1SMA70AT3G provides reliable overvoltage protection in a compact, cost-effective surface-mount package.
