It can be used to regulate AC power and DC power and is used in various types of motor, heating, and refrigeration applications. Additionally, TLZ20B-GS18 can provide protection from EMI and RFI interference in sensitive electronic circuits.

Working Principle

TLZ20B-GS18 is a Bi-polar diode, which means it can conduct in both directions and is polarized to allow only one direction of current flow. The diode is formed by a P-type semiconductor material and an N-type semiconductor material and connected together. When a voltage is applied to the diode, a small electric field is formed and the electron’s mobility is increased, allowing the current to flow. The direction in which the current flows is determined by the applied voltage. When the voltage is positive, the current will flow from the P-type material to the N-type material.

The TLZ20B-GS18 is a Zener diode, which means that when it is forward biased, it will allow current to pass through. However, when the voltage across the diode exceeds a certain voltage, known as the Zener voltage, the diode will enter a reverse breakdown region and start passing a controlled amount of current in a reverse direction. This reverse current is known as the Zener current and is used for voltage regulation.

The Zener current for the TLZ20B-GS18 is specified at 18V, so the voltage across the diode can be regulated to a maximum of 18V. This makes the TLZ20B-GS18 ideal for use in systems where a precise and stable supply of power is needed. The diode can also be used in series with other diodes to increase the total voltage regulation of the circuit.

TLZ20B-GS18 can also be used in parallel with other Zener diodes to increase the current rating of the circuit, as well as provide additional voltage regulation. This can be used in applications requiring large amounts of current, such as lighting and power supplies. The Zener diodes will also provide protection from EMI and RFI interference.

Conclusion

TLZ20B-GS18 is a single Zener diode that can be used for voltage regulation and current limiting in low and high voltage circuits. It has a wide range of applications and can be used in consumer and industrial applications. The diode\'s Zener voltage is specified at 18V, making it ideal for applications requiring a precise and stable source of power.

Additionally, TLZ20B-GS18 can be used in series or parallel with other Zener diodes to increase the current rating of the circuit, as well as provide protection from EMI and RFI interference. For these reasons, TLZ20B-GS18 is an ideal choice for many applications.
