TVS diodes are specialized diodes that protect sensitive electronics from voltage transients caused by electrostatic discharge (ESD) or electrical fast transients (EFT) by limiting the voltage levels which can reach the circuitry within the device. In many cases, such as consumer electronics, ESD protection is vitally important, as the device must reliably withstand ESD events without the user having to take any special precautions.

The PGSMAJ75A R3G diode is a unidirectional transient voltage suppressor (TVS) part, designed to protect against electrostatic discharge (ESD) and electrical fast transients (EFT). It is a member of the PGSMAJ family of ESD protection diodes supplied by ON Semiconductor. The PGSMAJ75A R3G has breakdown voltages of 12.7 MPa (14.5 V) and 10 MPa (17.5 V), and will protect against ESD events and EFTs up to levels of 30 kV at contact discharge and 8 kV at air discharge, meeting the requirements of IEC 61000-4-2 level 4.

The PGSMAJ75A R3G has an unidirectional breakdown voltage of 12.7 MPa and a continuous operating voltage (Vmax) of 7.75 V, making it suitable for many applications across a range of industries and sectors such as consumer electronics, telecommunications, computing and automotive. When designed into the appropriate circuit, the PGSMAJ75A R3G can greatly improve the protection of essential components.

The PGSMAJ75A R3G diode works by diverting damaging transient voltage away from sensitive components when it reaches the critical breakdown voltage. When a voltage transient greater than 12.7 MPa occurs, the PGSMAJ75A R3G will quickly divert the transient away from the circuit’s sensitive components. Once the transient has passed, the diode will return to its normal state, allowing the circuit to continue operating normally.

The PGSMAJ75A R3G is supplied in a DFN-3 package with an exposed-pad for improved thermal performance. It is designed to operate in both high-temperature and low-temperature environments, and has a low leakage current, so it can be used with a wide range of operating voltages. The PGSMAJ75A R3G also has a high surge capability of 100 A peak and is RoHS compliant.

In summary, the PGSMAJ75A R3G is a unidirectional transient voltage suppressor (TVS) diode, designed to protect against electrostatic discharge and electrical fast transients (EFT), that is suitable for a wide range of applications across a variety of industries, including consumer electronics, telecommunications, computing and automotive. With a breakdown voltage of 12.7 MPa and a continuous operating voltage of 7.75V, the PGSMAJ75A R3G will protect components from dangerous overvoltage transients and provide maximum protection from ESD events and EFTs.
