Application fields

BZV55-C7V5,135 Zener diode is widely used in many industries, from consumer electronics to telecommunication systems. As a protection device, it can be used in a wide range of applications such as electrochemical sensors, EMI/RFI filters, voltage-translation devices, voltage reference circuits, and in rectification circuits such as voltage multipliers. It can also be used in automotive circuits, power supplies, and solar hot water systems.

Working principle

If the anode voltage is higher than the cathode voltage, the diode allows current to flow through it. This is called a forward bias current. The current then flows from the anode to the cathode, but not vice versa. On the other hand, when the voltage on the cathode is higher than the anode, the diode will take a reverse bias current. This current will not allow passage of the current. However, the BZV55-C7V5,135 diode does not just totally block the current, but rather it limits its passage.

When the voltage reaches a certain level, typically 7.5V, the Zener diode will break down and start conducting current in the reverse direction as well. This ensures an even voltage level on both sides of the diode. This breakdown voltage is exactly why BZV55-C7V5, 135 type of diodes are called Zener diodes and can be used in voltage-translation devices, power supplies, and all kinds of other applications where voltage control is needed.

Conclusion

In conclusion, BZV55-C7V5,135 Zener single diodes offer a unique protection mechanism which helps keep voltage levels consistent in all kinds of electricity-dependent devices, like power supplies and voltage-translation systems. They are quite simple in terms of construction, a diode with two parts – anode and cathode – and have a wide range of uses, from EMS/IR filters to solar hot water systems.
