Application Field and Working Principle of GDZ36B-E3-08

GDZ36B-E3-08 is based on a single zener diode and its associated components. It is designed to provide a stable voltage clamp to protect circuits from voltage transients. This is a 3.6V 6W zener diode, designed to provide a wide range of protection for various circuits. The diode has a low dynamic resistance, low clamping voltage, and low internal capacitance. It also offers high efficiency and excellent RF immunity.

Applications

GDZ36B-E3-08 is suitable for ESD protection, power bypassing, power line transient over-voltage protection and data line clamping. It offers efficient protection of signal lines such as CANbus, Bluetooth and specific communication buses.

It is suitable for protection of I/O and signal line against transient over-voltage. It is also well suited for board level Lightning Surge protection (LSP) in general commercial and industrial applications. It can be used in lids and modular control systems, and is compatible with IEC Class I & II apps.

Working Principle

The GDZ36B-E3-08 is a single zener diode based protection circuit. The zener diode is connected in series between the protected signal line and ground. This prevents voltage transients from exceeding a certain level, clamping them to a safe voltage. The zener diode acts to shunt the negative portion of a transient over-voltage spike to ground, creating a sort of flywheel effect that drains the transient energy.

When a transient over-voltage is sensed, the zener diode reduces the voltage to a safe voltage level. This is aided by the connection of an external capacitor and resistor on the zener diode block. Due to the reversible installation of the zener diode, the device is able to accommodate both positive and negative-going transients. The design ensures that the device absorbs the transient energy effectively and quickly, limiting the possibility of circuit damage.

Conclusion

The GDZ36B-E3-08 is a single zener diode based protection circuit suitable for protecting circuits from voltage transients. The diode has a low dynamic resistance, low clamping voltage, and low internal capacitance, ensuring excellent RF immunity and efficient protection of circuit components. It can be used in various circuits such as I/O protection, power bypassing, power line transient over-voltage protection, and data line clamping.
