TVS (Transient Voltage Suppressor) diodes are devices that protect electronic circuits and components from the damage caused by sudden changes in voltage. They are commonly used in computers, smart phones, printers and other electronic equipment. Of the many types of TVS diodes available, the SMBJ170CA-HRA is particularly useful for its ability to indicate electronic overvoltage protection and clamping capabilities in one single package.The SMBJ170CA-HRA, manufactured by Diodes Incorporated, is a bidirectional, unidirectional, or bi-directional "transient voltage suppressor" diode used for overvoltage protection. It has a low-profile, surface-mountable design and is suitable for a wide variety of applications, including automotive, computer, and server system, power supply, consumer electronics, and medical electronics.The SMBJ170CA-HRA is a low-capacity diode with a maximum peak pulse power rating of 170 watts, which is ideal for protecting small circuits. In addition, the diode has ideally suited for automated pick-and-place assembly due to its low profile, with an operating temperature of -55 degrees Celsius to 125 degrees Celsius and a maximum power rating of 1.2 watts.The SMBJ170CA-HRA\'s applicationfield includes various consumer, automotive, and commercial electronics. In automotive applications, it can help protect against short-circuit conditions, such as those that might happen when an automotive battery is discharged and then suddenly recharged. It can also help protect from power surges in power supplies, helping to ensure that electronic equipment isn\'t damaged due to sudden changes in current. It can also be used in circuits that require bi-directional protection, such as those used in computers, where input and output current are often reversed.The working principle of the SMBJ170CA-HRA is between avalanche breakdown and Zener breakdown. When a voltage is suddenly applied to the diode, the diode reacts by clamping the voltage and dissipating it as heat. This helps protect circuits from damage caused by overvoltage conditions. The diode also acts as an "avalanche brake" to help regulate current in the circuit, ensuring that current surges don\'t cause costly damage to sensitive components. As such, it is an ideal device for protecting sensitive electronic components from overvoltage damage.The SMBJ170CA-HRA is also equipped with several safety features. It has a wide operating temperature range, a low leakage current of 5 microamperes, a fast response time of 2 nanoseconds, and a low operating voltage of 13.2 volts. In addition, it has short circuit and overvoltage protection, and can withstand over-voltage and over-current transients caused by switching power supplies. Its full-surface mounting makes it suitable for automated assembly, and it is certified for safety standards such as RoHS, UL, and CSA.In short, the SMBJ170CA-HRA is an effective and cost-effective device for protecting circuits and components from the damage caused by overvoltages. It has a low profile for automated placement and a wide operating temperature range, making it suitable for a variety of applications. Its fast response time, low leakage current, and protection from over-voltage and over-current transients make it a safe choice for sensitive electronics. As such, it is an ideal device for any circuit or system in need of reliable and effective protection from overvoltage damage.
