The BZM55B2V7-TR3 is a single, Zener diode that is part of a broader class of components known as diodes. Diodes are two-terminal components that provide a range of functions in electronic circuits. The diode type selected can influence the operation and performance of a particular electronic circuit, and the BZM55B2V7-TR3 should be chosen and specified accordingly.

The BZM55B2V7-TR3 is a Zener diode, which is designed to pass current in one direction only, with a reverse breakdown voltage that allows the diode to conduct current in the opposite direction at a specified voltage rating. This function is beneficial in applications such as stabilizing voltage levels and protecting sensitive circuitry.

Features

The BZM55B2V7-TR3 diode has a voltage rating of 3 V, with a total power dissipation of 500 mW, and a forward voltage drop of 0.7 V at a current of 50 mA. The rated reverse-voltage breakdown of the diode is clocked at 3 V.

The device is manufactured in a SOT-23 case with a plastic zinc-oxide body, accompanied by a printed circuit board. The Zener diode is sensitive to variations in temperature, so the rated power dissipation must be adjusted accordingly to ensure a reliable operation. The available temperature coefficient is negative and ranges from -5 mV/°C to -0.5 mV/°C.

Applications

The BZM55B2V7-TR3 can be used in a variety of general-purpose applications. It’s particularly useful in voltage regulation and voltage stabilization circuits, often used to maintain a constant output voltage in power supplies, as well as in logic-level switching circuits and reference circuits.

It is also an ideal choice for overvoltage protection circuits, in which the Zener diode is used in combination with a larger power device to regulate the voltage. This type of design helps to protect circuit components from spikes of high-voltage current, which can reduce system reliability and cause damage.

Working Principle

The BZM55B2V7-TR3 Zener diode operates on the principle of breakdown voltage. This occurs when the electric field in the junction exceeds the reverse-breakdown voltage of the device. When this occurs, a current will start to flow in the opposite direction, allowing the diode to clamp the output voltage to the specified breakdown voltage rating.

The diode has a reverse recovery time, which is the amount of time it takes for the diode to transition from the forward to the reverse direction after the source voltage is removed. This feature helps to reduce noise, as well as improve signal integrity, in a wide range of electronic applications.

Conclusion

The BZM55B2V7-TR3 is a single, Zener diode that is suitable for a variety of general- purpose applications. Its simplified design, low power dissipation, and temperature coefficient make it an ideal choice for a number of applications, from voltage regulation and voltage stabilization to overvoltage protection.

The device operates on the principle of breakdown voltage, allowing current to pass in the opposite direction at a specified voltage rating. It also features a reverse recovery time, which helps to reduce noise and improve signal integrity. Taking all of this into account, the BZM55B2V7-TR3 is the ideal diode for many electrical and electronic projects.
