The AQ3118-01ETG from Littelfuse is a bidirectional Zener TVS diode designed for overvoltage protection in automotive applications. It has an 18V reverse standoff voltage and a nominal clamping voltage of 38V. The device can handle a typical peak pulse current of 2A under an 8/20µs waveform.
This TVS diode features extremely low junction capacitance of 0.3pF maximum at 1MHz, making it well-suited for high-speed signal line protection without degrading signal integrity. It is rated for operation over the full automotive temperature range from -40°C to +125°C.
The AQ3118-01ETG is housed in a compact SOD-882 surface-mount package, enabling space-efficient designs. With power line protection not supported, this device is intended for signal line applications where fast response and low capacitance are critical.
