1SMA8.5AT3G is a 400W unidirectional TVS diode manufactured by Littelfuse. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, ESD, and other surge events. The device features a reverse standoff voltage of 8.5V and a clamping voltage of 14.4V, ensuring that downstream components are shielded from overvoltage conditions.
With a peak pulse current rating of 27.8A, this TVS diode can handle significant surge energy. The junction capacitance is 1265pF at 1MHz, which should be considered for high-speed signal lines. The device is not intended for power line protection, as indicated by its general purpose application classification.
The 1SMA8.5AT3G is housed in a surface mount DO-214AC (SMA) package, which is suitable for automated assembly and space-constrained designs. It operates over a wide temperature range of -65°C to 150°C, making it robust for harsh environments. The part is RoHS and REACH compliant (unverified) and has an MSL rating of 1 (unlimited).
