SMF16A-E3-18 TVS - Diodes

Overview

SMF16A-E3-18 is a surface-mounted diode assembly comprising two ultra fast, unidirectional protection devices, a pair of ‘Series’ diodes connected in anti-parallel, designed to protect equipment against short duration and high surge events. They are specified for very fast response, and are ideal for interfacing between power lines, such as AC mains and DC circuits, or when no geometrical isolation is necessary.

Features

• Low dynamic zener resistance
• High peak pulse power capability
• Low leakage current
• High breakdown voltage
• Excellent clamping capability
• Ultra fast response time
• Built-in flame retardant base material

Application field

SMF16A-E3-18 TVS - diodes are designed for protection of sensitive circuits against over-voltage transients caused by AC mains transients, lightning, inductive load switching, static discharge and more. It is used in many different environments including outdoor and indoor AC mains, telecom protection and protection of your equipment from damaging electrical impulses.

SMF16A-E3-18 diodes are also used in high voltage AC and DC power transmission systems, including solar and wind energy systems, and they are also often used alone or in series with other protection devices for board level ESD and lightning protection.

Working principle

SMF16A-E3-18 TVS - Diodes are designed to be triggered by a sharp rise in voltage due to a transient event, providing a very fast response time that is not dependent on temperature. The construction is a pair of Ultra Fast diodes connected in Anti-parallel. When a transient voltage rise is experienced, the diode acts like a high impedance until the voltage reaches the breakdown voltage level, at which point the diode begins to conduct current. This limits the voltage rise going to the protected circuitry, and prevents damage to sensitive electronic equipment. The diodes require a very low operating current, typically in the microamps range, so they can easily be integrated into any existing circuit without consuming power.

The SMF16A-E3-18 TVS - Diodes have a high peak pulse power rating, enabling them to withstand the pulses caused by large over-voltage events. The diodes also feature an excellent clamping capability, allowing them to absorb high levels of transient voltage without damage.

Conclusion

SMF16A-E3-18 TVS - Diodes are designed to protect sensitive circuits from over-voltage transients caused by AC mains, static discharge or lightning. They feature a very fast response time, high peak pulse power capability, excellent clamping capability and a low operating current. SMF16A-E3-18 is an ideal solution for any application requiring fast and reliable protection from over-voltage events.
