The SZ1SMA48CAT3G is a bidirectional Zener TVS diode designed by Littelfuse Inc. for overvoltage protection in automotive applications. It features a reverse standoff voltage of 48V and a clamping voltage of 77.4V at a peak pulse current of 5.2A. With a peak pulse power rating of 400W, this device provides robust transient voltage suppression.
This TVS diode is housed in a DO-214AC (SMA) surface-mount package, making it suitable for automated assembly and space-constrained designs. It operates over a wide temperature range from -65°C to 150°C, ensuring reliability in harsh environments. The component has a capacitance of 135pF at 1MHz, which is typical for Zener-based TVS diodes.
Designed for automotive use, the SZ1SMA48CAT3G meets the rigorous demands of vehicle electronics, protecting sensitive circuits from voltage spikes and transients. Its bidirectional configuration allows it to clamp both positive and negative surges, simplifying circuit layout. The part is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified.
