BZX55F2V4-TR

Diodes - Zener - Single

The BZX55F2V4-TR is a type of diode within the Zener family, primarily used for voltage regulation. It allows a current from an AC or DC source to flow in one direction, while preventing the flow from the opposite direction. Such a diode can act as an electrical barrier that only allows the current to pass through in one direction, thereby controlling the mixture of direct and alternating currents.

Zener diodes, like the BZX55F2V4-TR, consist of a lightly doped p-n junction with a higher doping ratio on the side of the junction connected to the cathode. The advantage of Zener diodes over other types of diodes is that they are designed to operate when a reverse bias voltage is applied, meaning that they become “forward-biased” once the applied voltage is greater than the reverse breakdown voltage. This allows them to protect electrical circuits from excessive current flow. For instance, they can protect against over-voltage and over-current by diverting energy when the circuit reaches an unsafe operating level.

The BZX55F2V4-TR Zener diode has a maximum power type and a power voltage rating of 600mW and 4V, and a breakdown voltage of レBZX55F2V4-TR・. Due to its low power rating, the BZX55F2V4-TR is primarily used in low power applications, including RF generator and voltage limiter, plus also providing output control or low-power signal rectification. It is also suitable for a variety of different buffer and driver applications, allowing it to act as a bridge between AC and DC components in a circuit.

The BZX55F2V4-TR is also suitable for protection applications, such as voltage reference sources, voltage regulation, and circuit protection. When used for circuit protection, the diode works by increasing its resistance as the voltage rises above the operator-defined limit. This then diverts the extra current to a pin or group of pins, preventing the circuit from being damaged from over-voltage or over-current. Additionally, the diode can also be used to limit the voltage to the safe operating level.

Moreover, the BZX55F2V4-TR has a maximum surge power rating and operating temperature of 3W and -20 to 70°C, respectively. Other features include an Isolation Voltage of 500V, an operating frequency of up to 200kHz, a wide operating temperature range of between -55 to 150°C, and a capacitance of 10pF. In addition, it has a wide storage temperature range and a junction-to-ambient resistance of 22.5KΩ.

In conclusion, the BZX55F2V4-TR Zener diode is an ideal solution for a wide range of applications, including RF generator and voltage limiter, plus output control or low-power signal rectification, voltage reference sources, voltage regulation and circuit protection. Its wide operating temperature range, surge power rating and junction-to-ambient resistance make it an ideal choice for many different projects.
