Transient Voltage Suppressors (TVSs) are devices used in most applications to protect sensitive electronics from transient voltage events. The SMAJ24A-M3/5A is a unidirectional TVS diode optimized for operation over a wide voltage range and extended temperature range. It is designed to protect applications from electrical interference such as Electrostatic Discharge (ESD), Switching Transients, and Voltage Transients.

The SMAJ24A-M3/5A has an exceptionally low clamping voltage, which is required for protection of sensitive electronics in consumer, industrial, and automotive applications. The design of the SMAJ24A-M3/5A also ensures protection against particular levels of ESD, as defined by the IEC/EN61000-4-2 international standard. This makes the SMAJ24A-M3/5A an excellent solution for high frequency, single-line protection schemes.

The SMAJ24A-M3/5A features new larger cathode and anode leads. This allows higher power rating and easier handling. The new cathode and anode leads have improved contactability with the PCB and provide more robust stress immunity. The improved stress immunity helps protect against mechanical damage and reduces the impact of unstable conditions on the operation of the device when connected to the PCB.

The SMAJ24A-M3/5A offers superior surge capability compared to conventional TVS diodes. The device provides reliable protec-tion for all common signal levels from flat line to high frequency transients. The SMAJ24A-M3/5A also provides a wide range of applications where common mode surge protection is required, such as signaling lines for bus networks, signal input protection for CCTV equipment, or audio/video equipment.

The SMAJ24A-M3/5A works on the principle of a voltage dependent resistor (VDR), and utilizes a reverse biased P-N junction diode. The device limits its current conduction when subjected to a voltage transient and absorbs the energy by clamping the applied voltage to the breakdown voltage, specified per part number. This helps ensure that the connected electronics are not exposed to damaging currents or voltages, which could lead to permanent damage.

The SMAJ24A-M3/5A is highly reliable under the most severe operating conditions and offers superior clamping performance with very low breakdown voltage. It is also designed to reduce insertion losses, which is important for high frequency applications. The diode also features very low leakage current over its operational temperature range.

In summary, the SMAJ24A-M3/5A is an excellent choice for single-line ESD protection, high frequency applications, and long life TVS protection solutions. It is designed for both consumer and industrial applications, and provides superior protection against transient voltage stress. The device can be used in a wide variety of TVS and ESD protection applications and offers excellent performance and reliability.
