The SZ1SMA16CAT3G is a bidirectional Zener TVS diode from Littelfuse designed for automotive transient voltage protection. It features a reverse standoff voltage of 16V and a maximum clamping voltage of 26V at 15.4A peak pulse current. With a peak pulse power rating of 400W (10/1000µs), it provides robust protection against voltage spikes in 12V vehicle electrical systems.
This device is housed in a DO-214AC (SMA) surface-mount package and supports an operating temperature range of -65°C to 150°C. It exhibits a typical capacitance of 375pF at 1MHz, making it suitable for high-speed data line protection. The diode is not intended for power line protection and is optimized for automotive applications such as engine control units, sensors, and infotainment systems.
Its bidirectional configuration allows protection of both positive and negative transients on a single line. The SMA package offers a compact footprint for space-constrained designs, and the surface-mount assembly simplifies automated manufacturing. Compliance with AEC-Q101 (automotive qualification) is typical for this series, though not explicitly verified in the available data.
