The SA64CA TVS diode is a high-performance device designed to protect sensitive electronic equipment from voltage transients induced by lightning and other sources. It was developed for use in sensitive automotive applications, such as infotainment systems, cameras, and automotive interiors. The device operates by providing a low-impedance path for transient currents, while protecting against over-voltage events.

The SA64CA TVS diode utilizes a reverse standoff voltage of 14V, and a low stand-off clamping voltage of 10V. Its low clamping voltage makes it suitable for use in 24V automotive systems. The device works by diverting transient voltage away from sensitive components, while clamping the voltage to a safe level. The low clamping voltage helps to ensure that sensitive components are protected from current exceeding their operating voltage. It also reduces both EMI and current stress on the device.

The device is offered in standard SMD package and is ideal for use in automotive and consumer electronics applications. It offers low leakage current and excellent ESD protection. The SA64CA also features integrated ESD protection that is designed to support automotive interface standards such as USB 2.0 and LVDS. The device has an operating temperature range of -40°C to 85°C.

The working principle of SA64CA TVS diode is based on its breakdown voltage. When a transient voltage is applied to the device, the voltage reaches its breakdown voltage and the doping regions of the PN junction become conductive, allowing current to flow. The device then clamps the voltage to its low clamping voltage, allowing the current to pass through but protecting the other system components from transient voltages. This prevents damage to the other components in the system.

In summary, the SA64CA TVS diode is designed to protect sensitive electronic components from electrical transients caused by lightning and other sources. Its low clamping voltage and integrated ESD protection make it an ideal choice for automotive and consumer electronics applications. The device works by diverting transient voltage away from sensitive components, while clamping the voltage to a safe level, and helping to reduce EMI and current stress on the device.
