This article aims to provide an overview of the 1PMT5947C/TR13 application field and working principle.

Application Field

The 1PMT5947C/TR13 Zener-Single Diodes are often used in automotive, communication, consumer and industrial applications. These diode devices are primarily used for general purpose protection, signal rectification and voltage regulation. In automotive applications, the 1PMT5947C/TR13 diodes are used in ABS systems, airbags, ignition, vehicles seat belts and sensors. In communication applications, they are utilized for pulse generation, modulation and signal rectification purposes. For consumer applications, they are mainly used as voltage suppressors and voltage references.

Working Principle

The 1PMT5947C/TR13 diode works by the principle of the Zener effect. Essentially, the Zener Effect is a phenomenon arising from the Silicon chip that the diode is manufactured from. The main working principle of the 1PMT5947C/TR13 diode is that under reverse conditions where a reverse voltage is applied on the device, the voltage level is made to be clamped at the breakdown voltage, thereby creating a regulated output. The breakdown voltage is the set value at which a breakdown of the diode occurs, thereby releasing the excessive voltage thus clamping the output.

In addition, the Zener effect also occurs in the forward voltage bias condition of the diode where a small current flows through the device when the forward voltage is at or above the Zener voltage. This allows for the device to be used for signal rectification, signal firing and signal protection. It also has the ability to provide a voltage reference to the circuit, allowing the circuit to operate at some continuous voltage level.

Conclusion

In conclusion, the 1PMT5947C/TR13 Zener-Single Diodes are utilised in many different applications and can be used for signal rectification and voltage regulation. The diodes operate through the Zener effect where excessive voltage is released whenever the breakdown voltage is reached.
