The SMBJ series of bi-directional transient voltage suppressors (TVSs) are designed to protect low-voltage circuits against voltage surges of up to 400W and 600W peak pulse power. The SMBJ16A is a 16V, sub-miniature, bidirectional TVS diode designed for a wide variety of applications.

Applications

The SMBJ16A is used in a variety of applications, including digital systems, communication and networking equipment, and solid-state drives. It is ideal for use in automotive systems, medical equipment, power distribution systems, and other applications subject to occasional surges. It is suitable for SCSI, ISDN, V.35, LAN and telephone line protection. In addition, it can be used in conjunction with other 25V and 35V TVS diodes to protect sensitive components in automotive, medical, and industrial systems.

Working Principle

The SMBJ16A is designed to provide protection against electrostatic discharge (ESD) and other transients. It works by limiting the voltage spike on the input to a safe level. When a transient voltage exceeds the clamping voltage of the device, the TVS diode allows current to flow through it until the voltage decreases. This limits the amount of energy that can damage the circuit. The protection capability of the SMBJ16A device is determined by its peak pulse power rating (PPP), which specifies the maximum pulse energy that can be dissipated in the event of an overvoltage or surge.

The SMBJ16A is designed to have a fast response time. The device has a low capacitance, which helps to minimize signal degradation. It is designed to have a low leakage current and low device capacitance when in the off-state to reduce power dissipation. The device also has a low on-state impedance, which helps to reduce the voltage drop that occurs when the device is conducting.

Conclusion

The SMBJ16A is an ideal device for protecting low-voltage circuits against voltage surges and transients. Its small size, fast response time, low leakage current, and low on-state impedance make it suitable for a variety of applications. It has a high peak pulse power dissipation and is designed for use with other 25V and 35V TVS diodes. In summary, the SMBJ16A is a highly effective transient voltage suppressor device for protecting against ESD, overvoltage, and other transients.
