PGSMAJ30CAHM2G Circuit Protection

TVS (Transient Voltage Suppressor) diodes are semiconductor components that protect sensitive circuits from overvoltage transients such as electrostatic discharge (ESD) and electrical fast transients (EFT). Their fast response and low junction capacitance make them ideal for transient suppression applications in consumer electronics, telecommunications, automotive, and industrial systems. Among the most popular TVS diodes is the PGSMAJ30CAHM2G, a low capacitance, unidirectional transient voltage suppression diode intended for protection against ESD. The PGSMAJ30CAHM2G is designed for use in high-performance applications such as wireless charging, ac power lines, and USB ports.

This diode has a maximum clamping voltage (VCL) of 30V for a 5A current and has a lower parasitic capacitance than traditional ESD diodes. Additionally, its reverse stand-off voltage (VWM) is 28V, meaning that it becomes conductive when a voltage in the range of 28V to 30V is applied. This makes it suitable for general-purpose, ESD protection, as well as power line and I/O protection applications. The PGSMAJ30CAHM2G diode is offered in standard 2GHz SMAJ series O-ring packages and has an extremely low operating capacitance for improved signal integrity.

The PGSMAJ30CAHM2G diode is designed to provide a fast response time to protect against ESD and other transient voltage events. It has a low capacitance compared to other TVS diodes and is capable of handling high dV/dt transients. The PGSMAJ30CAHM2G is protected against thermal runaway and is epoxy sealed for robustness. The package footprint is compatible with the industry-standard SMAJRG-40, allowing for easy drop-in replacements in existing systems.

In general, the PGSMAJ30CAHM2G is an ideal diode for transient voltage suppression applications in consumer electronics, communications, automotive, and industrial systems. It is suitable for wireless charging, ac power line, and USB port applications due to its low capacitance, high dV/dt handling capabilities, and fast response time. Its efficient protection against ESD, EFT, and other transient voltage events provides extra peace of mind in critical applications.
