Diodes - Rectifiers - Single

The BY269TR is a Diode - Rectifier - Single one-time surge rated up to 500 Watts. The device is Silicon PNPN rated at 30 Volts maximum forward voltage at a current of 1 Amp. It is designed to provide overvoltage protection, voltage limiting, and short-circuit protection in sensitive and low-cost, line applications.

Applications

The BY269TR is commonly used in commercial, military, aviation, and industrial applications, where high reliability and small size are necessary. It is used in line-level applications such as reversing polarity in LEDs, switching power supplies, telecommunication equipment, high-voltage DC motor controllers, audio amplifiers and mixers, and power measurement instruments. Its surge rating and peak reverse current capability makes it ideal for protection signal transmission lines and preventing dangerous over-currents.

Operating Principle

This Diode is constructed with a special PNPN silicon substrate and has two electrodes: the anode and the cathode. When a positive voltage is applied to the anode and a negative voltage is applied to the cathode, the device turns on and the current flows through the diode in the forward direction. The device also offers a reverse blocking voltage of up to 30 Volts. When the current reaches its maximum rating and the voltage drops, the device turns off, blocking any additional current.

Features

The BY269TR offers several features and benefits, including low forward voltage, high surge rating (500 watts), high peak reverse current capability, low power consumption, and low internal resistance. It also features a silicon substrate which allows for a higher current rating and greater surge protection. These features make the device an ideal choice for power supply and electrical equipment applications that require a reliable and cost-effective diode with high surge protection.

Conclusion

The BY269TR is a compact and reliable Diode - Rectifier - Single device suitable for various line-level applications. Its surge rating and peak reverse current capability makes it an ideal choice for protection of signal transmission lines and over-current protection. Its low forward voltage and low power consumption also make it ideal for power supply and electrical equipment applications. Its silicon substrate allows for increased current ratings, greater surge protection, and a lower internal resistance.
