SMP20A-E3/85A

TVS (Transient Voltage Suppression) diodes perform a crucial role in circuit designs, helping to protect against damages caused by electrical surges or overvoltages. SMP20A-E3/85A is a type of TVS diode designed to protect against both ESD (electrostatic discharge) and EFT (electrical fast transients) events. It operates over a wide range of working frequencies, from 100 Hz to 100 MHz.

SMP20A-E3/85A is a unidirectional diode, which means it will only activate in the direction where the zener voltage is lower than the source voltage. Since it is a Zener diode, it can absorb energy to some extent when subjected to an ESD or EFT event. This means it will protect the circuit it is connected to from overvoltage or transient events.

SMP20A-E3/85A has an extremely low leakage current and a low maximum clamping voltage with its reverse stand-off voltage being 7V. It is also UL1449 certified, making it compatible with IEC61000-4-2 Electrostatic Discharge standards. This makes it an ideal choice for use in high-speed data signal lines and communication systems.

SMP20A-E3/85A is an excellent choice for applications which require reliable protection from transients and overvoltages, such as in consumer electronics, office equipment and other communication systems. It is also suitable for use in automotive applications, and works well with other automotive electrical components, such as ECUs and ignition coils.

It is also ideal for applications such as solar inverters and brushless DC motor control systems, as it can function reliably in extreme temperature environments. It is also rated for high surge current discharges of up to 20A. The device is also RoHS compliant and highly reliable, making it a great choice for long-term use.

In conclusion, SMP20A-E3/85A is a great choice for any application which requires reliable protection from transient and overvoltage events. It is capable of operating over a wide frequency range, and is certified for use in high-speed data lines. Additionally, the device is highly reliable and provides excellent protection over a wide temperature range.
