TVS - Diodes have been a mainstay in electronics for a variety of applications. The SMB8J6.5C-E3/5B is the latest in this growing family of devices. It is designed to protect against overvoltages in power supplies and data lines from over-voltage transients.

The SMB8J6.5C-E3/5B is a high-speed, high-reliability, low capacitance transient voltage suppressor chip, using technology developed by Vishay Siliconix. The device contains a reverse-biased diode array and is typically used in conjunction with a varistor, MOV, or other similar protection elements. The diode array is designed to suppress voltage transients which are over a few volts in magnitude, and typically referred to as "overvoltages".

The SMB8J6.5C-E3/5B device has several important features. It features positive temperature coefficient, which means that it increases in resistance as temperature increases. This helps to reduce voltage transients and therefore protect sensitive devices from them. Another feature is that it has an operating voltage range from -65V to +5V. The device is also rated for a maximum peak pulse current of 20 amps, which is ideal for use in power supply protection.

The SMB8J6.5C-E3/5B is designed for use in a variety of applications, including but not limited to power supplies, data lines, motherboards, modems, printers, and other electronic devices. In terms of power supplies, it provides protection against transients exceeding 100V in magnitude. The device is especially useful in ATX type power supplies, which are used for powering computer components.

The working principle of the SMB8J6.5C-E3/5B is based on the diode array contained in the device. The reverse-biased diodes in the array act as a voltage-limiting element and when a voltage excess occurs, the diode with the highest breakdown voltage is triggered into conduction. This limits the voltage to the device and ensures that any overvoltage events do not damage the protected devices.

The SMB8J6.5C-E3/5B is an important protection element in the move toward more reliable and safe electronic systems. By providing protection from overvoltage transients, this device helps to ensure that Sensitive electronic components remain safe and functioning at all times. The device is economical, reliable, and offers an enormous benefit in terms of electrical safety in today\'s world.
