• Introduction

  The 129NQ135-1 is a unipolarType A bridge rectifier diode with internal current leakage protection. It is used to provide over-voltage and under-voltage protection in applications that involve resistive and capacitive loads. The device is also capable of providing voltageFault prevention and currentFault prevention, resulting in more reliable operation in high power applications.

• Application Fields

  The 129NQ135-1 is used in a wide variety of applications. These include motor control devices, power factor controllers, power line surge protectors, uninterruptible power supplies (UPSs), industrial rectifiers and motor controllers. Furthermore, it can be used as a rectifier in a power system to provide voltage and current stability in critical applications. Additionally, it is used in automotive applications, such as electronic control units, immobilizers, and dashboard electronics.

• Features
  • High-Current Capability: The device can handle up to 1.5 Amps of continuous current.
  • High Temperature Resistance: Operating temperature range of -40°C to +125°C
  • Low Power Consumption: Low power consumption allows the device to run on lower power sources.
  • High Precision: High precision enables the device to offer precision protection against both overvoltage and undervoltage.
  • Low Response Time: Low response time allows for quick response to voltage changes.
• Working Principle

  The 129NQ135-1 has two terminals on its surface; One is the anode and the other is the cathode. When a voltage is applied between them, current flows from the anode to the cathode, allowing for switching of current in both directions. This switch action occurs as the diode moves between two voltage/current points and is referred to as the “forward bias”.
  The rectifier uses a special type of diode structure known as the Schottky diode. The Schottky diode is different from conventional PN junction diodes in that it is formed from a metal-semiconductor junction instead of a PN junction structure. This type of diode can switch between the two voltage/current points more quickly and offer superior protection against overvoltage and undervoltage.
  In addition, the 129NQ135-1 has an internal current leakage protection feature that provides protection against overvoltages and undervoltages. When a voltage is applied to the diode, the internal current leakage protection mechanism senses any current leakage and shuts down the diode, preventing any further current flow.

• Conclusion

  In conclusion, the 129NQ135-1 is a type A bridge rectifier diode with internal current leakage protection that is used to provide overvoltage and undervoltage protection in applications that involve resistive and capacitive loads. The device is capable of providing voltage fault prevention, current fault prevention, and has a high precision that allows for precision protection against both overvoltage and undervoltage.
