TPSMP43AHE3/85A

TVS - Diodes

TVS (transient voltage suppressor) diodes are a specialized type of diode used to protect delicate circuits and components from damaging electrical transients, such as those brought on by lightning strikes or AC line surges.

The TPSMP43AHE3/85A is a general-purpose TVS diode housed in a DO-214AA package. It is designed to clamp transient voltages up to 305V peak with a minimum response time of 8ns. The device is suitable for use in high-speed communication, automotive, and medical applications.

Working Principle

TVS diodes are designed to protect sensitive electronics from overvoltage transients. When a transient voltage exceeds the diodes\' breakdown voltage (also called clamping voltage), the diode rapidly conducts current in reverse. This clamping action limits the voltage across the protected circuit to a safe level.

The TPSMP43AHE3/85A is a general-purpose diode that is designed to protect against transient voltages up to 305V peak. It contains two diodes connected in series which enable it to provide ± clamping voltage protection. It also features parasitic suppressor capacitors, which provide additional transient protection.

Applications

The TPSMP43AHE3/85A can be used in a variety of applications where protection from transient voltage surges is required. These include:

• Automotive Electronics
• Industrial Controls
• Medical Equipment
• Telecommunications Analysis
• High-Speed Communications Applications

Conclusion

The TPSMP43AHE3/85A is a general-purpose TVS diode designed to protect against transient voltage surges up to 305V peak. It features ± clamping voltage protection and parasitic suppressor capacitors for added protection. The device is suitable for use in high-speed communication, automotive, and medical applications.
