TVS (Transient Voltage Suppressor) diodes are a type of diode designed to protect electronic devices from high voltage damage due to external electrical surges, load variation or other disruptive electrical conditions.

P6SMB170C is a unidirectional TVS diode device with 5% tolerance for peak pulse current, low leakage current and fast response time. It is available in an SMB package with low profile of 0.75 mm for surface mount applications.

P6SMB170C is a unidirectional diode designed to protect sensitive electronics from over-voltage transients. It provides excellent clamping capability and it is very low profile, making it suitable for handheld and small-form-factor applications as well as for other industries with space-restricted applications such as aviation and automotive electronics.

This particular device has 8 V to 170 V maximum operating voltage range. It has an average forward current of 1.0A and a peak forward current of 5.0A. Its peak forward surge current is 40A. It can stand between 15 A to 150 A peak pulse current, and it has a maximum working voltage of 170V. The clamping voltage is below 6V. Additionally, the maximum clamping voltage at 2A is 8V and the maximum clamping voltage at 5A is 8.6V. The maximum reverse working voltage is 5V. The maximum power rating is 1W.

The operating principle of a TVS diode is that it can quickly clamp a voltage surge within the diode\'s breakdown voltage. This process is achieved through a voltage-controlled diode structure that allows its conduction when the reverse bias voltage exceeds the voltage of the diode\'s junction, thereby forming an avalanche breakdown region. This type of breakdown voltage basically occurs when the reverse-biased avalanche voltage of the junction is exceeded. Once breakdown occurs, the diode will clamp the input voltage to its breakdown voltage level.

The main application of the P6SMB170C is to suppress over-voltage transients and provide circuit protection, due to its low leakage current. It is suitable for telecommunications, automotive power control, consumer electronics, personal care products, industrial and medical equipment, computers, and other systems that require circuit protection from outside disturbances.

P6SMB170C has the features such as low profile body, fast response speed, 8V to 170V operating voltage, high peak pulse current, low leakage current, Clamping voltage below 6V, and maximum power rating of 1W, which make it suitable for various applications.

In conclusion, P6SMB170C is an ideal choice for protection of sensitive electronics from electrical surges and other disruptive electrical disturbances. It offers low profile body with fast response speed and wide operating voltage with a high peak pulse current that make it an ideal option for many applications.
