Diodes - Zener - Single > TLZ11-GS18 application field and working principle

TLZ11-GS18 is a Zener single diode, which uses a low voltage Zener regulator with a wide range of voltages and a medium power. Zener single diodes can be used for voltage regulation, surge protection and stability.

The TLZ11-GS18 is constructed from an epitaxial layer of silicon. It is encased in an epoxy that has excellent flame profile and moisture resistance. The device has three terminals, one anode and one cathode, and additional gate or control terminal. It offers good temperature stability and a wide range of temperature coefficients depending on the power ratings.

The operating principle of a Zener single diode is based on the Zener effect. When the voltage across the device is beyond the Zener voltage range, a current flows through the device, creating a negative feedback control mechanism. This mechanism helps to regulate the voltage across the diode within a certain range.

The various applications of the TLZ11-GS18 include voltage regulation, reverse polarity protection, amplifier protection, and over voltage protection in circuit boards. They can also be used for control and sensing voltages in switches and power supplies. It is well suited for clipping, clamping and peak- rectifying circuits.

The TLZ11-GS18 also has a wide range of working temperatures, ranging from -65°C to +175°C. The working voltage range of the TLZ11-GS18 is typically 2.8V to 18V, with peak reverse voltage of 21V to 22V. The Reverse Design Voltage is accurately maintained at 11V during normal operation, with a tolerance of 2%.

In conclusion, the TLZ11-GS18 is a versatile Zener single diode, with a wide range of voltage regulation, surge protection and stability applications. It has a low operating voltage and a wide range of temperature coefficients, making it well suited for a variety of circuits and boards. Its temperature range and peak reverse voltage make it well suited for clipping, clamping and other protection circuits.
