SZ1.5SMC20AT3G Description

Short technical summary and product information.

The Littelfuse SZ1.5SMC20AT3G is a 1500W unidirectional TVS diode designed to protect sensitive electronic circuits from voltage transients. It features a reverse standoff voltage of 17.1V and a clamping voltage of 27.7V, with a peak pulse current rating of 54A. The device uses Zener technology for reliable overvoltage protection.

 

This TVS diode is housed in a DO-214AB (SMC) surface-mount package, suitable for automated assembly. It operates over a wide temperature range of -65°C to 150°C, making it suitable for demanding environments. The part is intended for automotive applications, providing robust transient protection in vehicle electronics.

 

With a single unidirectional channel, the SZ1.5SMC20AT3G is ideal for protecting DC power lines and signal lines from electrostatic discharge (ESD) and other surge events. Its compact SMC footprint allows for space-efficient PCB layouts.
