SM15T22A ST Transient Voltage Suppressors (TVS)

The SM15T22A is a 1500W unidirectional Transil TVS diode from STMicroelectronics in SMC surface-mount package, designed for protecting sensitive equipment against transient overvoltages. For selection, verify reverse standoff voltage of 18.8V, breakdown voltage range, clamping voltage at peak pulse current, peak pulse power of 1500W, low leakage current, fast response time, and operating junction temperature from -55°C to +150°C. Features include planar technology, compliance with IEC 61000-4-2/4-4/4-5 standards, and UL recognition. Ideal for voltage spike protection in 15V-20V power systems, industrial power supplies, communication equipment, I/O interfaces, and any 18V nominal circuit requiring 1500W unidirectional transient suppression.
