The P4SMA91A-E3/61 is a TVS (Transient Voltage Suppressor) diode developed and supplied by Vishay Semiconductor Diodes Division. This component safeguards sensitive electronics from voltage transients triggered by lightning and other voltage events, offering 400W power dissipation and a breakdown voltage of 91V.
The P4SMA91A-E3/61 is a surface-mount TVS diode in a DO214AC package. It is specifically designed to protect sensitive electronic components from voltage transients caused by electrostatic discharge (ESD) and other transient events. This diode offers a unidirectional configuration, meaning it can conduct current in one direction while blocking it in the opposite direction. Its specific voltage ratings, surface-mount package, and versatile applications make it a practical choice for engineers and designers needing reliable circuit protection.
The P4SMA91A-E3/61 has a voltage rating of 77.8V, which refers to the standoff voltage at which the diode starts to conduct. This rating indicates the maximum voltage that the diode can withstand without suffering damage. It also has a clamping voltage of 125V, representing the maximum voltage drop across the diode during a transient event.
The DO214AC package of the P4SMA91A-E3/61 TVS diode is a surface-mount package commonly known as SMA or SMC. This package offers efficient thermal dissipation and mechanical protection. It has two terminals for easy connection to a circuit board, making it suitable for automated assembly processes. The compact size of the DO214AC package allows for high component density on the PCB.
The P4SMA91A-E3/61 is widely utilised in various electronic applications that require protection against transient voltage spikes. Its robustness and reliable performance make it ideal for safeguarding sensitive components from voltage surges. Some typical applications include telecommunication systems, consumer electronics, automotive electronics, industrial equipment, and power supplies.
