The SMAJ8.5CA is an 8.5 A surface-mounted transient voltage suppressor from STMicroelectronics. This device is designed to protect sensitive electronics from voltage transients caused by induction, lightning and other damaging pulses. It is suitable for applications such as USB, telecom, datacom, computer circuits, and industrial electronics. This device has an operating voltage range of working between 6.5 V and 243 V and a peak pulse current rating of 135 A. The maximum clamp voltage is 10.7 V. The SMAJ8.5CA also features low leakage current (typically 0.1 µA at 25°C), fast response time (typically 8 ns), and is lead-free, compliant with regulatory standards such as RoHS and REACH.
