BZM55B4V7-TR Datasheet/PDFThe BZM55B4V7-TR is a single-diode Zener diode chip. It\'s used for protection against over-voltage and reverse-voltage applications. It has a maximum continuous voltage rating of 4.7V and a maximum power dissipation of 500mW. It has a breakdown voltage of 4.7V and a reverse current of 0.6mA. Its operating temperature range is between -40°C to 85°C.
The BZM55B4V7-TR has many practical applications. It is used in power supply designs, RF signal processing circuitry and circuit protection. It is also used as a voltage stabilizer, allowing it to regulate or maintain a specific voltage level within a circuit. It can also be used in over-voltage protection, where it will clamp the voltage when it surpasses the rated voltage.
The working principle of the BZM55B4V7-TR is quite simple. The diode is connected in a reverse-biased configuration, with its junction sitting above the anode voltage. A large reverse voltage applied to the diode causes its junction potential to exceed the anode voltage, leading to a breakdown of the junction and the flow of current. The Zener diode is able to self-regulate its voltage, making it a stable voltage source.
The BZM55B4V7-TR is a reliable and versatile diode. Its simple design and low cost make it a popular choice for many applications. Its wide operating temperature range, low power dissipation, and high voltage breakdown make it an ideal choice for use in power supply and over-voltage protection applications. Its ability to regulate voltage makes it an excellent choice for use as either a voltage regulator or stabilizer.
