Introduction

1N958B TR is a single-phase, low-noise, ultra-low threshold voltage of the Zener diode, can be used in high frequency voltage regulator and circuit parts, to effectively suppress various kinds of electrical interference, to reduce power supply peak value and the design of high precision systems. It is mainly used in high frequency voltage regulator, receiver front end and noise suppression, etc.

Working principle

When 1N958B TR works, electrical current flows from the anode to the cathode. When the voltage across the diode exceeds its breakdown voltage (reverse voltage), it conducts reverse current by the mechanism of impact ionization, so as to reduce the peak voltage.It has the ability to inhibit electrical interference and reduce the peak value of power supply, greatly improving the accuracy of the system.

Application field

1N958B TR Zener diodes has wide application field. It is mainly used in voltage regulator, receiver front end and noise suppression.

In the voltage regulator, it is usually used as negative voltage doubler, voltage doubler, three-level voltage transformer, and bias circuit of various circuits.

1N958B TR Zener diodes is mainly used in front end and pre-amplification circuit of receivers, which can effectively inhibit the interference of other signals and improve the input signal to noise ratio.

In noise suppression, it is used as return protection and return discharge circuit. A positive and negative polarity thunder-protective diode series connection is usually used as the return protection circuit of communication and information receiving equipment, which can effectively prevent the equipment from being damaged by static electricity. The return discharge circuit uses the reverse breakdown of the diode to discharge the static electricity of the human body and the charged objects, so as to prevent the electrostatic attraction caused by static electricity.

Conclusion

In addition to the above, 1N958B TR Zener diodes can also be used in high frequency power supply circuits and constant voltage protection circuits. It has good work stability, small volume and other characteristics. Low breakdown voltage and high stability make it widely used in many fields.
