Applications

TZX6V8C-TAP is mainly used in AC/DC and DC/DC converters, where its high peak reverse voltage and low temperature coefficient make it ideal for these applications. It can also be used in DC/AC converters, where its low forward voltage drop and high efficiency are key factors in achieving a reliable output. This device can also be used in surge protection applications, such as in mobile phone chargers, and power supplies where the reduced size and cost are beneficial.

Working Principle

TZX6V8C-TAP is a single Zener diode, which relies on a process of break-over when the reverse voltage reaches a certain level. When this voltage is reached, the diode provides a conductive path between the anode and the cathode, allowing current to flow. This process, known as Zener breakdown, is responsible for the device’s ability to maintain a stable reverse voltage between the anode and cathode.

When the forward current begins to increase, the device begins to switch from linear to saturation mode. This is due to the increased current across the junction, which causes a large increase in the junction capacitance, resulting in a decrease in forward voltage drop, a reduction in efficiency and an increase in the device’s power dissipation.

When in Zener range, the device offers a relatively constant reverse voltage, meaning that its internal power dissipation is also relatively constant, allowing for greater stability. This also allows for a greater operating range, as the forward voltage variation is significantly reduced.

Conclusion

TZX6V8C-TAP is an ideal single Zener diode for AC/DC, DC/DC and DC/AC converters due to its high peak reverse voltage and low temperature dependence, giving it an excellent performance and controllability. This device is also suitable for surge protection applications, such as in mobile phone chargers, and power supplies, as it offers a low forward voltage drop and high efficiency at a relatively low price.
