1K SMB 110A is a Transient Voltage Suppressor (TVS) diode commonly used for transient voltage protection. The device is designed with an array of zener diodes connected in antiparallel to a PN junction to provide bidirectional protection. The device also features a built-in electrostatic discharge protection, making it an ideal choice for protecting sensitive electronic components from electrical shocks and other transient voltage events.

The device provides surge current capability up to 1 kilovolt and up to 110 amperes maximum peak pulse current. The 1K SMB110A also features low clamping voltage (Vc) and high surge capability, enabling it to provide up to 110-volt protection. The device has standard packaging with terminals that are Ni-Cu plated for excellent heat dissipation.

The working principle of the 1K SMB110A is simple. When a voltage signal above the breakdown voltage (VBR) of the device is applied, a transient voltage across the diode is generated, causing the diode to turn on and diverge current flow to ground.

When the voltage across the diode reaches the peak pulse current (IP) value, the diode begins to turn off, and the current flow is diverted back to its pre-event level. This allows the device to provide reliable protection against voltage transients. In addition, because of the fast turn-on and turn-off time of the diode, the device is able to react quickly to transients, providing excellent protection.

The 1K SMB110A is designed for use in applications that require transient voltage surge protection. Examples include: power supplies, computer systems, automotive electrical systems, telecommunications equipment, and general industrial usage. The device is also suitable for protecting valuable data lines, such as Ethernet, telephone lines, fax lines, and Internet connections.

With its high surge capability, low clamping voltage, and fast response time, the 1K SMB110A is a perfect choice for protecting sensitive electronic equipment from transient voltage events. The device can provide reliable and cost-effective protection against voltage transients, saving time, money, and effort.
