TVS - Diodes

TVS diodes, also known as transient voltage suppressors (TVS) diodes, are diodes specifically designed to protect electronic systems from high voltage spikes or surges. They are often used in automotive, industrial, and consumer electronic applications to safeguard sensitive integrated circuits (ICs) from damaging electrical transients. TVS diodes come in a variety of package types, such as SMA, SMB, SMC and SMD, as well as various reverse stand-off voltage ratings.

PGSMAJ90AHR3G Application Field and Working Principle

The PGSMAJ90AHR3G series TVS diode has a bidirectional low capacitance design in a small SMA package which provides rapid response and low clamping voltage. This device is suitable for use in applications such as high speed signal line, automotive electronics reciever and high speed backplane systems. It is designed to protect against electrical transients produced by lightning and other electrostatic discharge (ESD) events.

The PGSMAJ90AHR3G contains a Zener diode network which has high surge capability and low clamping voltage. The low capacitance design also ensures fast response to overvoltage transients. The Zener diode network acts to suppress electrical transients above the reverse stand-off voltage by diverting the current away from the protected components. The low capacitance design allows fast response to reduce the peak current seen by the protected components so that the device is not damaged by the electrical transient.

In addition, the PGSMAJ90AHR3G has a reverse stand-off voltage of 90V with a 25A peak pulse current handling capability, making it ideal for high speed signal line, automotive electronics reciever, and high speed backplane systems.

The PGSMAJ90AHR3G has a maximum carry current of 6A and a storage temperature range from -55˚C to 125˚C. It is also RoHS compliant and AEC-Q101 qualified for automotive applications.

In summary, the PGSMAJ90AHR3G TVS diode has a low capacitance design and a high surge rating, making it suitable for automotive, industrial, and consumer electronic applications. Its low capacitance design ensures fast response to overvoltage transients, while its reverse stand-off voltage and 25A peak pulse current handling ensure robust protection from damaging electrical transients. The PGSMAJ90AHR3G is also RoHS compliant and AEC-Q101 qualified, making it ideal for high speed signal line, automotive electronics reciever, and high speed backplane systems applications.
