The SMAJ28CA-TR is a bidirectional Zener-type TVS diode from STMicroelectronics designed for general purpose transient voltage suppression. It features a typical reverse standoff voltage of 28V and a maximum clamping voltage of 59V at a peak pulse current of 39A (8/20µs waveform). The device can handle 400W of peak pulse power, making it suitable for protecting sensitive electronics from voltage spikes.
This TVS diode is housed in a surface-mount DO-214AC (SMA) package, which is compact and suitable for automated assembly. It supports an operating temperature range of -55°C to 150°C, allowing use in harsh environments. The component does not include power line protection and is intended for general purpose applications such as I/O interfaces, power supply lines, and data lines.
The SMAJ28CA-TR is supplied in tape and reel packaging for high-volume manufacturing. Its bidirectional configuration allows it to clamp both positive and negative transients with a single device, simplifying circuit design and reducing component count.
